Good evening all, I'm having difficulty reading two (very dirty) Icom FR-4000-3 repeaters that I recently acquired for rehab. My software is CS-F3000 version 1.1 and I am using a genuine OPC-478

I have both of these duplexers available to replace an existing system. The site itself is a water tower with an existing DB224 that has been made available to me. It is mounted at the very

I think they should be on the same side of the tower 12 feet apart. My frequency is 53.050 input is 52.050

If the coax to the T is 50ohms, then yes , an electrical 1/4 wavelength of 35 ohm coax from the T to the feedline. You could less ideally alternatively do two 1/4 wavelength 75 ohm coaxial cables

Got a picture? Is it a DB212-2 or home brew or what??? [email protected]> wrote:

Yes.? The TKR851s (and 751s) were developed and manufactured after the TKR850 Ver 2s were developed.?? In other words, all of the x51s are Version 2 radios. Between the shop and several local ham

And, (it bears constant repeating) original Astro CPS will launch/run on both 64 and 32 bit Windows but it will only physically talk to the radio on 32 bit. Astro Tuner lets you select higher com

The original modules are roughly 4" X 6" and about 1.25" tall, not sure how you would fit anything bigger in there. Then you would have M100s running off a badly designed 35 year old power supply with

I am using a Kenwood D700 radio with MMDVM STM32 hotspot I tried using it as a repeater for the local area for emergency and regular use I putting the radio in packet mode 9600 baud open modes

Question:Has anybody replaced the original radios in a R100 with M100 radios ?Wd0biaGary

Yes, Bob, compared with the Grey KMC 27 mic, the black KMC35 mic does sound good. I am being picky. To me the gold standard mic audio is a Motorola SyntorX/ X9000 with the cap closest to the mic cord

The KPG-91D software is valid for the 750/751/850/851. And it is backwards compatible with pre Version 2 TKRs as

After 8 years of working with them, and thousands of radios, Ive never noticed any issues with audio quality on those out side of faulty mics that had bad cords or were otherwise broken. Yes, the new
