This topic might be a little personal preference to some people.????? What I'm looking for is the following.
?
1. Which models of Motorola gear will work best in the ham radio DMR space.?? Example: Motorola model 5000E with Serial number X to Y works well.
2. Which models are most likely to show up in the used market for ham use.
3. Which one will hook up to DMR network without having to jury rig everything.??
?
I'm not as familiar with the Motorola gear as I as I am with Hyteria and Kenwood.
?
Thanks!

Re: Motorola R2600 VGA Output
Wonder if it's the only one supporting that 66.6Hz MAC speed.

PIctures, John please.?? Did I remember to post that the OEM whip replacement for the TH-F6 is about $134 ?? And it is a special order from Japan.? Yikes.
Also, I've posted my tests on four more brands on the web site. Under tech, under RF projects.
I've got the last three or four coming from Amazon in about the next two weeks. They take a while to get here.

<-- Great! - I located Jared's diagram and made up a cable this
morning.? One correction to the diagram (at least for my R2660A Test
Set), the DB9 on the test set is a Female, so the DB9 on the cable
should be a Male.? I can draw up a nicer diagram and post it to the
files section.
So once I made the cable, I tried it with the VGA input on my old 19"
DELL monitor.? The encouraging news is that the monitor does detect a
video signal (since the DELL RGB screen saver disappears), but I get a
message "cannot display this video mode".? So now the hunt is on for an
Acer V196WL.
Thanks for the info, and nice work Jared!

I have several of these available. They look to be very clean and test well at 100W out with 1-4W input. I tried them down to 440MHz and there was no change in power output. Crescend makes these in a variety of input power ranges but the only change is
the value of the attenuator at the input stage of the amp. In the past I have ordered different value attenuators from Crescend and changed them to 10W input or 25W, etc. $400 each including shipping to lower 48.

Dr 3000 /xpr8300 VHF no RX no Tx
good afternoon I have a problem with a Motorola Dr3000 vhf (xpr8300) the repeater turns on, goes through its entire control cycle and goes into standby, the problem is that it does not transmit or receive, I checked the programming and everything is in order, it does not transmit or receive in either digital or analog. I checked the cables but it does not seem to have any problem, the LEDs remain on in standby, the Power ones and the analog and digital ones, the tx and rx LEDs do not light up when I try to excite it with a radio. do you have any advice? thanks

Re: Reality check on capabilities of GRMS repeater
Larry,
?
I'm trying to build a GMRS repeater using CDM1250 radios, ID-O-Matic IV and one of the inexpensive six bay duplexers. While I'm waiting for the ID-O-Matic delivery, delayed for weather, I quick-shipped an interface cable to me and connected everything. I believe the radios are 'repeating' and I hear audio in the Rx CDM radio when I key-up/use one of the HT's I'm testing the system with BUT I don't get any audio out of the HT's. It seems like I'm getting some COR with the HT's - but no audio/voice. I'm stumped.?
One more thing I just don't understand is the below.?
In red is says 'programmed for pin-8 COR'. Where is pin-8? Is this something I modify in the CPS?
- With two 16 pin rear accessory connectors wired to the controller (one for TX radio, one for RX radio) for plug and play to make an instant repeater from any two compatible Motorola radios (Any Motorola radios with 16 or 20 pin rear accy connector, programmed for pin-8 COR active low (or high changed in programming). For CDM radios, use center 16 pins.
- WITH VOICE AUDIO IDer board wired to and tested with above.
?
How about the below? I don't 'get' what or where these pins are and how to modify them if needed and unfortunately, I don't have anyone to help me with this. I hope you, or someone on the thread, can & will help me muddle through this. When I 'get it' and I'm sure I understand it all, I will create a .pdf guide with pictures and explanations to help the next person who attempts it. I'm freshly retired, have a lot of time to do these things now and this is one I had 'shelved' for when I had the time..? Thanks in advance. gregg at wardlow.org
Gregg N4RGW - WQLY786
Motorola radios using 16 or 20 pin rear accy connector?pins
TX radio pins:
Pin 2 Mic Hi (audio in) (WHITE to pin 11 IDOM4)
Pin 3 PTT active low (GREEN to pin 3 IDOM4)
Pin 7 Ground (BLACK to pin 1 or 12?IDOM4)
RX radio pins:
Pin 7 Ground (BLACK to pin 1 or 12 IDOM4)
Pin 8 COR (active low is default for IDOM4) (BLUE?to pin 7 IDOM4)
Pin 11 discriminator audio out (YELLOW to pin 8 IDOM4)

Re: Reality check on capabilities of GRMS repeater
Buy an all in one package ready to go? You got everything and your GMRS license.? Wait you will regret it if you don’t get a very good quality Lightning arrestor & a nice run of copper wire and a couple of ground rods with nice copper nuts to ground things and please remember to ground the hardline LDF 4-50 before the lightning arrestor. ?

Next up is build or buy? Personally I went the "build" route last year and built several ham repeaters out of Motorola CDM radios. I've done both straight FM as well as DMR.

And then I had to spend a lot of time figuring out how to disable "VBS and Credential Guard" so that VirtualBox would run with reasonable performance on my modern machine. You'll need a spectrum analyzer to tune the duplexer. You'll want a nano-VNA to check the feedline/connectors/antenna. You'll need crimpers to attach the connectors. You'll want a power meter to check the transmitter.? Lots of little rabbit holes to go down before getting to the end. In the end it took months. But I learned a lot and am happy with the experience.

For the controller an MMDVM board with the raspberry pi will do FM. But the audio quality of that solution on FM is not perfect, a little noise gets in there. The MMDVM/rPi is what you'd want for a digital voice mode repeater, but not for FM GMRS. It is also a much more complex solution. For a GMRS repeater I'd use a simple ID-O-Matic board. Cheaper and much much simpler to set up.

If you decide to buy then a local radio shop will happily sell you the equipment, program it, tune it, and install it.? Or take up Jonny on his offer, that sounds like a good deal to me.?
