Skyler, Simply: The FM transmitter and receiver have to pass data at 9600 bits per second. And, stay within the channel bandwidth limits. This is for the Digital modes DMR, P25, D-Star and

Something I haven’t seen mentioned in the thread below so far: a proper digital repeater will apply error correction to the received signal before retransmitting it as a clean digital

One other requirement comes to mind in that the receiver IF response curve is different for digital , in that the top of the curve needs to be flat, with rounded corners, not bullet shaped as in the

Hi Skyler, You are correct on the disc > FM audio. And correct about no filtering. I am suspicious on requirement of the frequency tolerance to be +/- 150 hz. That may be more for the potential

I don't know anything about the GM600 but I would say try it and it may very well work. I am using a pair of M1225 and they work just fine. Your bigger challenge will be getting the levels set

Hello everyone, I have some GM600 from an old trunking network, and I would like to use them to build some D-Star repeater. I had read some information about but I can't get decent audio from the

Skyler, On your last point while this is an issue for subscribers on DMR the repeaters do not rapidly key/unkey. They transmit full-time whenever there is valid activity (local or remote) on either

Sounds good, Mike but I did not get a reply. I take it you did go to the web site to see my current email address?? Link below in all my signatures. -- Regards, Karl Shoemaker To contact me, please

Well first, you need flat audio. Directly or as closely tied to the discriminator and modulator as possible. Filtering will prevent digital signals from making it through. Correct me if I’m wrong

Well, you can, and if the repeater audio is good enough (like simplex is) it actually works (Fusion does on my system, even through the remote base). But that will probably make the repeater owner

Here is what it looks like, located somewhere in Tennesee?? Still don't know how much you want for it?

There’s at least one nationwide network of 900 repeaters on Allstar. Easily 75 nodes. Mine is one of them. GeorgeC W2DB

No one can normally not just transmit digital voice thru a FM analog repeater. For DSTAR the receiver side of making an analog repeater work is easy, just take the digital signal off the recvr

I would, but I'm a "freeloader" at the tower.? I'm allowed space there because I'm the local "caretaker" - I check in on the place from time to time and let workers in when needed. There is internet

Hi Karl, I sent a reply.... about $25 for shipping to the USA. Will send Canada Post . Etransfer $$ once I have shipped the unit and have receipt from the Post Office and can tell you the exact

Have you looked into adding allstar and linking with other repeaters? Works good here.

Curious as to why you're selling?? Is it because you don't have any users? That seems to be the biggest issue with mine - I have *very* few users.? Fortunately, the site I'm at is very accommodating

Frank- I have had 2 of those fail... 2 different applications.. See my other post here for my recommendation.

I can't say for sure, but one reason for carbon composition is that they're inherently non-inductive, hence non-reactive, and wouldn't affect the tuning or add inductance or capacitance to the

What makes a digital voice capable repeater dv capable? Is there nothing special about it and hence I can just transmit digital voice such as p25, dmr, c4fm, or d-star to the analog (fm) repeater and
