Hi Tom, Most certainly, they should be replaced. Everything electrolytic in the station should be replaced, IMHO. SSCB/SCB, uniboard, injection amplifier, ICB, IPA/ regulator. Cheers, Sam KJ6QFS

Good evening all- Thanks to the recommendations of the group and the great write-ups on RB I have completed the recap. One more question- I don't see any mention of replacing caps on the control

If you scan pieces of the Kendecom documentation and upload them as files to the group's FILES section, they can be moved to the repeater-builder Kendecom area for all to benefit.

Yep? I could use that? also. Currently working on a KRP-5000 UHF..?? this Model has? no? Docs. on the RB?? Kendecom page.Neal Ka2CAF?The back plate with the Terminals.

Hello Frank, I think I built this before the Pi days. Also, with the ID-O-Matics, I don't have to be concerned about powering up or down and only need them to ID. Good luck with your project. Mick -

Thanks Mick, I had a pair of Maxtracs with an Id-O- Matic4. Worked very well. I later replaced the controller with a Pi3. Frank N6CES (TARRA) <tarra@...> wrote:

Yes, the M1225 setup would be similar. I have a pair of them next to my desk for a test repeater. I also have a VHF/UHF set up for a portable cross-band repeater. It uses a pair of ID-O-Matic ID'ers .

Hi Don, Not the logic board, I have that doc. I'm looking for the back board, the one that the logic board connects to and has the terminal blocks on the back of the unit. I know it is mostly an

Scott If you mean the KRB 5000 logic board document, that shows the interconnection between the other boards, Yes I have a copy and will reply to you via private message with a scan of it attached.

Hi Lloyd, I've been thinking about using a pair of M1225 radios. Are the characteristics similar?? Frank N6CES wrote:

I agree with what Rick said... All audio should be normal, no companding Make sure each channel is set for 25kHZ not narrow 12.5 Lloyd KO4L

We will try these settings, Thank you!!!

Hello Aron, This can be very controversial and I am not familiar with the CDM1250, but let's assume it is the same as say the Vertex Standard VX5500/ VX6000 radios which we joined together for a

Yes Preemphasis/deemphasis should be done in the radios (i.e. Rx audio should be "filtered" which includes deemphasis, Tx audio should be preemphasized, or "mic" audio). The RICK should be set for

Bingo! And THANK YOU. I don't think I'd have ever thought to enable that feature. Makes sense, now that you point it out. It is now working properly with the MMDVM modem acting as controller,

Hi and good evening, we have two CDM1250s that we made a Repeater out of, we are using the Motorola Rick HLN3333B, for whatever reason the audio sounds lousy and I can’t get it to sound normal, can

Jim, I have never played with a motorola xpr8400. I'll make this suggestion just in general as I had a problem setting up an icom fr-4000. It turned out that the mmdvm board didn't like a narrow

Hi,?Yes, I Always used something like RG213 or RG214.?On some rare cases I would run directly to the antenna if there was a couple feet of free cable that could take up if there was flexing.? Best

Do you have "Disable repeat path" enabled? It needs to be enabled for it to operate as a duplex base rather than repeater. If you are able to select "External PTT" under audio priority, that tells me
