[Repeater-Builder] Kenwood Radios For Sale - TM-241 (VHF) available, TM-441 (UHF) Sold
Hi All, Update, I have sold the TM-441 UHF radio, thanks to those who were interested. I still have the TM-241 (VHF) available. Suitable to connect to a DHE RBI-1 remote interface for repeater/remote linking. See below for discription if you are interested. Still US$175.00 including shipping to the US. Regards Kevin Thanks to the administrators permitting this message. -Hi All, - -Hope you don't mind this For Sale message. - -I had a Remote interface using a DHE RBI-1 connected to our Link-Comm RLC-3 controller. -We decided not to continue with the install and pulled it from operation. Never actually opened it to the users. -I have recently parted with the RBI-1 interface and now have the 2x radios, Kenwood TM-241(VHF) and TM-441(UHF) SOLD that were being used, now surplus to needs. -These radios have had little use and are still in very good condition. I have checked these recently and are still working fine, power is still 5,10 and 50/45 watts. -Condition is in good condition, I can supply photos to those of you interested. -These radio have had a couple of mods done to them. -1. They have been frequency expanded -2. I removed the SO-239 sockets and replaced them with bulkhead BNC connectors. These gave us a fix connector for extra support. - -They will be sent in the orignal boxes with manual and non-DTMF mics (came with them). - -The only missing item is the power cable. I had these connected in the repeater system and they are missing. I have included the power connector to the radio, will only need the fuses put in line. -Any further questions would be best sent direct to me. - -I will ship these to the US if anyone wishes. Please contact me directly at sparczn(No-Spam)@gmail.com - -Of course price US$150.00 plus US$25 to ship each - -Thanks -Kevin.

Re: [Repeater-Builder] Adding Extra Cavities to Duplexer
Dave, I'm not familiar with that particular duplexer, but I will take a stab at this. I have had some experience adding to duplexers, re-cabling, etc. I am assuming the additional cans are identical to the ones used in your duplexer and that if there is a difference between high pass and low pass cans that you have one additional of each. You should be able to get at least 100 dB with the additional cans. If the original is really giving 80 dB at your frequency separation, theoretically you may see 120 dB. The cabling will have to be exactly right to see that much, and you'd better have very well shielded cables everywhere or leakage may spoil the 120 dB notches. Insertion loss should increase about 50%. If it is 2 dB now, it should be about 3 dB with the added cans. I would duplicate the cable type and length that is used between the existing cans. Use the same connector types also. And if there are T connectors on the cans, use the same type. Good luck and let us know your results when you're finished! 73, Paul N1BUG David Struebel wrote: I have a Phelps Dodge 506-1 four cavity duplexer.

The cabling between the cans is still 1/4 wavelength in coax, right?? since I will have to add some cabling...I have seen some discussion in the duplexer info on the site about maybe using a diffrent length cable when adding more cavities...

Sounds more like one or both of the radios have a microphonic VCO. If you're *really* confident with hot-air rework of surface mount stuff you can try fixing it yourself by very carefully reflowing the solder in the VCO section without dislodging or overheating any components. I can't remember exactly if the GM300 has clip-on or soldered VCO shields (it's been around 7 years since I was last in a Motorola service shop). If they're soldered you'll have to remove the shields first and then resolder them afterwards (without damaging, dislodging or overheating any components under or around the shields). Alternatively, send them to your local Motorola service shop for repairs. Cheers, Rodney. -- === Rodney Baker VK5ZTV rodney.ba...@iinet.net.au === Alternatively

Thanks for the info. My surface mount warfare skills aren't what i would call the best. I think i am going to leave them how they are for right now for the test phases of the set up . If and when it becomes something of a permanent install , Ill either send them out for repairs OR ill switch them out for 2 CDM 1550ls+ i have in the shack and mobile.

Thanks everyone for their feedback. I have two reeds on order from MDM and will just go with that.

[Repeater-Builder] Re: GM300 repeater build ?2
These radios are out of depot service, so Motorola probably won't touch them. Usually you just get a blank 8-pin RJ-45 and short the hangup pin to ground so that PL will decode correctly (I don't remember the exact pin numbers at the moment - sorry). It could be just local mic audio being injected since your likely keying the TX using the accessory connector. If your convinced that its an internal problem, I'd try seperating the logic and RF boards to reset the interconnection between them (could just be oxidation or something acting like a pickup).

Re: [Repeater-Builder] Re: Two questions
The connector you are looking for is on the IF-Audio-Squelch board. The connector is numbered with pin 1 below the notch and pin 5 opposite the notch. The signal you want is present on pin 1. It is also present on the interface connector for the module on pin 4. This is the signal level at the output of the second crystal filter and is very low until the signal is very strong. The documentation for an IF-Audio-Squelch board is available on the Repeater-Builder.com site. Look for LBI 19D417707. --- On Wed, 5/13/09, w4sef w4...@localnet.com wrote: From: w4sef w4...@localnet.com Subject: [Repeater-Builder] Re: Two questions To: Repeater-Builder@yahoogroups.com Date: Wednesday, May 13, 2009, 3:15 PM OK Jim, THANK YOU for that info!

Lots of signals can be copied full quieting before the first limiter starts to show a reading. On the P S controller, you have to hook up to the CTCSS input on the GE exciter board to get the signal from the controller into the system. Look closely at the instructions from P S to see what connections have to be added. Just plugging the controller in does not get the CTCSS signal to the exciter. 73 - Jim W5ZIT --- On Sat, 5/9/09, w4sef w4...@... wrote: From: w4sef w4...@...

I would like to be able to monitor the signal incoming. Also, be able to see if there is any rise in meter reading with no signal coming in to check for desense with the transmit on and off. I had a Micor and knew where to tap the second limiter for a meter reading on signals but can not find the right place on the Mastr II. Also, I am using the Pion Controller board. I love the controller but I can NOT get it to transmit the CTCSS tone. I have tried every setting I can think of using the computer to program it but no luck. It will DECODE fine but will NOT send the tone! Any ideas? Thanks Steve W4SEF
[Repeater-Builder] Re: GM300 repeater build ?2
All connections were done via the 16 pin connections on rear . No mics via front panel , just a rj45 jumper in front for hang up. I switched the radios out for my cmd1550's and problem disappeared . I reprogrammed one of the gm300's for general use and when i turn up the volume i get crazy feedback with and without a mic while RCVING any signal. Im in the process of reprogramming one of the other ones to see if it does the same thing.

Sets on the left side top as viewed from the front. Has a toggle switch extending through the front panel with three positions. Fast, slow and center not scan.
