Review Summary For: Commtel Com 104 Reviews: 1 MSRP: discontinued (90 when new) Description: This Product Comtel Com 104 is handheld, has the Ref.-No. B110H and the Products Barcode is 5 021196 067122. Features: 20 programable Channels plus 1 Monitor Channel, Search Function, Lock-out Function, Keylock, BNC Antenna Conector, flexible Rubber-Duck Antenna, two Second scan Delay and built in Charging Circuit for the six nicd rechargable Batteries. This Scanner has two Power Conectors, one is stated as for Charging the Battiers and one for an external Power Supply. Frequency Coverage: 66-88Mhz, 137-174MHz and 380MHz-512MHz in FM only. A Soft Cover made of Plastic is provided together with this Product. Product is in production More Info: Today that money would be about 90 Euro. Mine has the Serial-Number C004212. Stronger Signals nearby the listening Frequncy give a lot of QRM and on a Hilltop when the Signals come in even stronger, this Problem becomes MASSIVE (even with that small Rubber-Duck Antenna). A Scanner even in this Price class shouldnt be that bad. The Receiver is not sensitive like the FT-817ND and fails to pick up Signals the FT-817ND can hear strong and clear. However, I could hear a local Repeater with this Scanner and some other local Stations. The pin in the external Power Supply Slot broke long time ago, although I handle Equipment carefully, CHEAP JUNK !http://ceibsmobi.com/UploadFiles/bravia-ex650-manual.xml

Distributed by Commtel UK Ltd www.commteluk.com I rewired mine to use it as a master socket, and I have connected the other extensions to the filtered output. This can improve broadband speeds: see Weirdly, when I put my hand over the LNB the signal strength improves! The keypad doesn't work. Not a lock-out, it won't work at all. Pulled the back, loosened the bulk, to the pad, cleaned and reassembled, still not working properly. Any ideas? Answer questions, earn points and help others. The COM203 is identical to the Realistic or Radio Shack PRO-39 and made by the same company (GRE), although the band coverage may vary (see coverage below).The later COM204 and PRO-43 models have the same operating controls but different frequency bands and the ability to switch between AM and FM on any band at will (the COM203 uses FM on all frequencies apart from airband where it switches to AM). Performance Its not a particularly sensitive scanner. On airband my cheap Maycom 108 scanner is much more sensitive.The Commtel also suffers from breakthrough on airband from strong local amateur radio transmissions on 144 MHz.On the plus side, the Commtel and Realistic scanners are very cheap second hand, the batteries last a long time and they can stand a lot of abuse.My Commtel also has a matching carying case which gives it some protection against light rain.http://el-master.ru/userfiles/bravia-kdl-40v2500-manual.xml

Coverage and model variations 68-88 MHz (US version has 30-54 MHz instead) 108-174 MHz (Switches automatically to AM on airband frequencies) 380-512 MHz 806-960 MHz (US version has gaps from 824-851 MHz and 869-896 MHz to prevent access to analogue cellular frequencies) It is possible to modify the coverage by adjusting jumper diodes. This can enable the blocked cellular freqencies or swap the 68-88 MHz for 30-54 MHz and visa versa. If you have the skills you might be able to add a switch to allow coverage of both 30-54 MHz and 68-88 MHz by switching the jumper diodes over. There are modifications and jumper information available elsewhere on the internet: Memories The scanner has 10 banks of 20 channels where frequencies can be stored.200 memories in total, plus 10 Monitor frequencies which act as temporary memories when looking for new signals.Normally the scanner will scan all 10 banks of memories, but when it is scanning you can press the buttons on the front to remove any of the banks from the can process. The scanner can scan up to 25 memory channels per second. Programming the memory channels Press MANUAL Key in the memory number you want to use Press PGM (PGM will light up on the display) Enter a frequency (using the number decimal point keys) Press ENTER to store the frequency in the chosen memory. Repeat this process until you have programmed in all your chosen memories. Scanning the memories To start scanning the 200 memory channels press SCAN. Pressing DELAY will cause the scanner to pause for 2 seconds at the end of each transmission so it does not start scanning and miss the other side of the conversation (DLY will be shown in thew display). If the scanner stops on a signal you do not want to listen to press SCAN to continue the scan. To stop scanning press MANUAL. You can remove any block of 20 memory channels from the scan by pressing on the appropriate button. You will see a bar in the display under the blocks you are currently scanning.

This allows you to have all your aircraft frequencies in one block and all your amateur radio frequencies in another so you can scan one without the other. Selecting memory channels manually Key in the number of the memory channel you want to listen to and press MANUAL To move through the memory channels keep pressing MANUAL and the scanner will switch through the 200 memory channels one at a time. Scanning using the limit function Press PGM Press LIMIT Enter the lowest frequency you want to scan from Press ENTER Press LIMIT Enter the highest frequency you want to scan to Press ENTER Press the up arrow and the scanner will start to scan from the lowest frequency set. The scanner will stop on a transmission. If you want to keep a note of this frequency you can store it in the current temporary monitor memories by pressing the MON button. If you have stored a frequency in the monitor memory you can return to the limit search by pressing LIMIT followed by the up or down arrow. You can also scan up or down manually from any one of the 200 memory channels. Using the Monitor channels To listen to the memorised monitor channels press MANUAL then MON and then the number of the monitor memory you want to listen to. The monitor channel you are listening to is indicated by the bar under the memory number in the display. You can move stored frequencies from one of the temporary monitor memories to one of the permanent 200 memory channels like this: Press MANUAL Enter the channel number you want to move the monitor memory frequency to. Press PGM Press MON Select the correct monitor memory Press ENTER Priority Channel To program the priority channel do this: Press PGM Enter the channel number you want to use as the priority one. Press PRI P appears in the display whenever you are on the priority channel. To turn on the priority channel function press PRI (PRI will appear in the display).

The priority channel will be checked every two seconds and the scanner will switch to it if a signal is present. To turn off the priority function press PRI again.

Not saying anyone is lying, I've just been there and done that with the LW-150 and hated, I repeat, HATED to let it go, but I did. I do, however, still have my 1975 Penetrator. What can I say?. I tried it.. I WANTED it to be better!.

I had already used the Penetrator for at least 6-7 years and HOPED I had finally found a better antenna than the Penetrator that would upgrade my station performance, and look oh-so-cool while doing it.. I loved the build quality of the LW-150 and was proud to be the first in my area to have one.. I thought it was beautiful and if anything, I was biased in IT'S direction.. I conducted tests for a month and finally, tired from all the hopeful but fruitless attempts to find that magic formula that would cause the Penetrator to take a backseat to the LW-150.. I had to concede that the LW-150 was just not going to beat or even approximate the performance of the Penetrator and reluctantly,. I sold it. Now I wish I still had it just for testing and posterity sake, and to show off the build quality. I'd probably have it up just for a 2nd monitor rig, but it's gone and I've never really missed it. I would compare it's performance to a Maco that was installed maybe 10'-20' higher than the Penetrator. It was good but just didn't hang in there for the distances that the Penetrator did. I also recall a few others in town who later installed one of the copies and just couldn't keep up with my Penetrator station. I read their claim of 1-1.7dB more than a.64, and I fully believe that is possibly correct, I just doubt the angle of gain. Near-field tests may have shown gain, but my far-field tests showed loss. Thank you again for such a well-written and researched article, you actually had me considering trying one again,.until all the memories came back at how disappointed I remember being. It was a beauty and I sure wanted that to be THE antenna of choice. If you have one, use it and enjoy it, but I still believe a.64 will get your signal farther, ground wave. My Sigma 4 was the best performing omni I ever owned.

Although to be fair, I lived in a relative hole, and my range didn't extend much further than about 30 miles, and the people who noticed my increase in signal all lived within 5 miles of me. I now live at a much higher elevation, but I can't do the same A-B comparison to see how it works at different distances. Radio Shack's.64 wave found it last summer NOS. I also have a Penetrator put away but it needs to be overhauled. I had it on a 30' push up pole but took it down because I didnt like the way it waved around in the winds.I was wondering if you could possibly scan the manual you have for me.I used the sigma 4 to check into a 10 meter net Saturday night (using the internal tuner in my Icom 746) and i managed to talk to a few locals.However!?!?! If you live in a flat area and want to do the best ground wave signal possible, there is only one way to do it.I would expect that there is a set length for a certain frequency of choice, and a certain gamma adjustment which will be the only length providing a 1:1 resonance for that specific frequency of choice. Is there more to it than that, and if so, please explain!?! I set my LW-150 BY THE BOOK and tuned it to as near a 1:1 swr as possible. So are you saying I did something wrong.Where the story begins.I spoke with him about two years ago at length about this very antenna and the shocker of all shockers was that he told me that this antenna was designed by a guy at Avanti who had no formal technical training at all and was 100% self taught (nothing wrong with that but just giving the background). Your quoted article while interesting has several fatal flaws in it. This antenna is one half wave above that cone. I relay this story for two reasons, One is that I LOVE that antenna and used one for years and always wanted to know about how it worked, and number two is that I get upset when technical errors get propagated among people who are trying to learn and they are taken as gospel truths.

That is an extremely inappropriate statement, given that if you disagree, then you must be unbelievably dumb. I have been into this hobby for over 30 years and I know just enough to be dangerous, but I am posting this because the write up is in error and very misleading. The only thing worse than no information is disinformation and it is my one big pet peeve with the radio hobby.I talked to one of the guys that was on the design team at Avanti back in the day. I spoke with him about two years ago at length about this very antenna and the shocker of all shockers was that he told me that this antenna was designed by a guy at Avanti who had no formal technical training at all and was 100% self taught (nothing wrong with that but just giving the background). The only thing worse than no information is disinformation and it is my one big pet peeve with the radio hobby.If that is the case, and they knew it, then why did they rate the S4 with a higher gain value. Also I find the part about the designer having no formal education to be interesting. It brings me back a number of years, to when educated people were always telling me that the things I was building would never work. Heck I didn't have enough formal education then to know any better. But my lack of education allowed me to build them, and the funny thing is that often the things I made DID work. And only after analyzing them and figuring out why they worked was it understood. So many times knowing too much makes people say no to things before they ever try them to see if, in fact, that they might just work pretty well after all. I know I've said it before when the subject of this antenna comes up, but I owned one and for me, it was the best performing omni I ever owned. So if any (or all) of this is true, then what accounts for my superior performance observations.

Maybe it is in the angle of radiation, and the fact that I was in a relative valley compared to many of the others in the area may have played a part in this antenna being ideal for me (An Astro Beam on top of a 40' tower finally bested it). But one thing's for sure, it's no A99. And don't blame the hams. CB'ers also stick to some strange theories.I'm not the one who doubts the S4. Unfortunately, I no longer live where I did in the 70's and 80's when I did my signal comparisons, so anything I might do now, would need a new set of reference data for a proper comparison. Initially impressed because those of you who replied kept it polite as the day is long, and secondarily because I'm now interested when you begin to imply that known physics can be manipulated to achieve positive results rather AGAINST the book. OK, so, who has done this and what exactly are your measurements. It would seem it's time for someone to begin to market a real Skelton-pole. Thank you for your time, energy and patience, I'm just now beginning to imagine plans for renewed antenna testing enthusiasmismz.I have at this very moment a total scratch built Sigma IV laying out here in my yard. I too would like to see some guideline dimensions to help me optimize this antenna. It does tune up fine but before I put it up I would like to see some details which may help. The 6063 reinforced really makes this antenna stand up nice. I never did like the super flexy versions and especially the Sirio as the thing was like a fly rod with a 15lb fish in even a light breeze. I think what I need to do is see if I can call the guy on the phone and ask him to answer again all these questions and give the background for the antenna and then post the audio file here on Grumpy's. I think it would be informative and interesting for everyone to hear this for themselves.

He did not deny that it was a good antenna at all, in fact he said it was very good, but he also said the dimensions were super critical for good performance (as has been said for many years). Frame alignment is considered lost when the bit B2 in the received time slot TS0 is in error three times in succession in those frames that do not contain frame alignment signal. Signaling information is transferred in time slot 16. TS16 can be used for Channel Associated signaling. The multiframe consists of 16 successive frames, numbered 0.15. The multiframe alignment signal 0000 indicates the beginning of the multiframe. The subrack chassis is made of stainless steel. The subrack must be situated in a weather-proof location, either indoors or in an outdoor cabinet. By using mounting accessories included in the product it can also be installed in 500 mm ETSI-type racks. Air deflectors can be mounted above and below the subracks as required. Each section consists of four unit locations. The section borders are indicated with a dashed line in the figure above. By using jumpers the sections can be joined to create larger sections. The subrack allows installation up to 4 x DB2 Multiplexer. It is therefore possible to split the 17- slot motherboard into two, three or four sections. 8 -slot motherboard can be split into two sections. 19 NDM SUBRACK T37870.01 Commtel Networks Proprietary14 DB2B with 2 Ch. Comprises a common multiplex unit (MUX) and a variety of tributary units (VF and data). Allows adding enhanced features simply by adding tributary units, without having to upgrade the multiplex unit's existing software. Has a time-division multiplexed bus structure (ITU-T G.704) that allows flexible utilisation of the equipment's transmission capacity. Allocation of time slots is independent of the physical placement of the unit.

With VF channel units, provides an analogue interface with signalling adaptations ranging from subscriber signalling to various types of junction line signalling. Supports both channel-associated and common channel signalling. Allows the use of subscriber line testing in subscriber applications. All units are managed through the multiplex unit's service interface. Most of the controls and settings can be done without any jumper modifications. Software settings are used to set, for example, the following functions:- Time slot selections- Level settings- Impedance settings- Signalling and data interface parameters- Loopbacks- Alarm functions. Functions of DM2 In the Receive Direction are: Convert the input signal complying with ITU-T rec. G.703 to agree with equipment logic sections, disassembling the line code, generate the Rx direction clock signal. Synchronise to the incoming signal frame Control the demultiplexing occurring in the channel units Monitor the error ratio of the received signal and recognise AIS. Barista Training Manual - wavescoffee.com. and Training Manual - gkspl.in training manual.Training Manual Solar Water Heater Consultants. This is an antenna few US residents are familiar with or will ever buy. First off, the instruction sheet, is 1 page. With 4 diagrams showing stages of completion, virtually no step by step instructions. But not that hard to figure out. The antenna is very flimsy. Imagine holding a 31 foot whip antenna, and you have gotten the idea. The completed build quality is of POOR construction. The J-pole section (similar design to the old Avanti Sigma 4)is also built rather shabby. Also carrying a unbalanced 31 foot whip-like antenna around your yard isn't the most fun you could have. This was a small percentage of the time however. However still not as good as a Hygain Penetrator or an Imax2000. Although it has lower recieve noise than the Imax. If it lasts a New England winter I would be surprised.

My opinion is its not worth the trouble. It would probably out-hear any other vertical in that situation, and you may be able to hear distant DX sooner and better as well. MAYBE. The Sigma 4 or BT104 will outgun your Golden Pentrator by 1 S point on RX and TX. Its a shame all these Italians are not made like they perform. I will be in RX all day.Im hearing east coast all day at the moment. Whats your call sign? 73 Tim 26 OP 141 If I find a Avanti Sigma 4, I will let you know. I will be on Friday and try to shout you, although I have been very bust lately and haven't been up there. Thanks for your comments. The Leonid Meteor shower is taking place the next few days, and I have one of the few automated radio meteor listening stations on the east coast. Meteors reflect radio signals as the ionize in the atmosphere. Thanks Again. The Vector 4000 wipes the floor with the IMAX and A99. As to standards of construction, once again I am surprised to say you found it poor, its at least as well made as the other antennas you mentioned. Its a strange world when two people can have the opposite opinion of the same products, but I guess thats what makes life interesting.Broke three times in the wind and alumunum split in half on the big hoop. So, had to save what i could salvage and scrap the rest of it. Performed good though. At one point several years ago, I had a neighbor 6 blocks away who had one of the good old Larry's LW-150s. It weighed about 25lbs and used high quality collars with allen bolts which joined each section to the next. Very high quality thick wall aluminum construction, definitely the BEST BUILT vertical I've EVER seen. He was running new 9913 coax, I was using 15yr.Our ground elevation was identical, his 4 section mast was on the top of his two story where my 5 section with Penetrator500 was only on a 12' flattop roof.But, that thing did perform well. I had one years ago, but, didn't know how to set it up correctly, so, i sold it.

Kicking myself now for sure. Taking one antenna down and putting the other one in its place. This was repeated several times to see that signals remained constant. The 6 RX stations giving my TX were reports were all at least 35 miles away in 4 different directions. I noted their TX also.No RX station knew which antenna was being used. They were referred to antenna 1 and 2. (Its surprising how many people are bias over different brands!) I know it’s not the most scientific way of seeing what’s best. I don’t have any field equipment or meters to do this but at least its a good comparison. There are so many variable factors that can change what you believe is to be the best. I’ve yet to compare the two antennas back to back. 73 Tim 26 OP 141 Oreint Pirate Radio Group Some of us like such reports. Maybe i'll try a new vector and a new penetrator500 just to see if the new ones do any better. The antenna was so quiet when I first put it up in place of my A99 I thought it was broken, I turned the volume up to check the rig and swr then somebody gave a call, I got such a fright I dropped the microphone. It was a realy good antenna both rx and tx but the physical size was a problem with my neighbours so it had to go. Sadly missed antenna. 73s Phil M6MRP Yaesu FT817nd, FT840 FT51R.
