Help with TK-5820 and P25 in general

[garretcanter]

I have a TK-5820 that I am trying to program for P25. I am new to P25 (very familiar with DMR but not P25). I am trying to access Motorola HAM repeaters that are in conventional mode. It should be RX and TX frequencies, NAC, my unit number, and talk ground number strapped. Are the talk group numbers supposed to be in decimal or hexadecimal? I cannot hear any repeaters, although it looks like they might be coming up due the strength meter showing a signal. I changed the receive NAC to F7E to eleminate the NAC, but that did not seem to work. What am I missing? Sorry to bother folks, but I am just trying to learn.

The talkgroups are entered as HEX in KPG-112.

Why are you entering TGIDs for a conv HAM repeater?

They're commonly used to segregate traffic. One near me uses TG 1 for local traffic and TG 10 to route traffic across a V.24 bridge.

Got it. I guess my point was to simply test with TGID 1 before doing anything else. It's not that complicated.

$FFFF talk group ID will open/hear on ANY talk group ID. Think of it as the group ID version of F7E nac. When you TX All talk groups will receive/hear you—it’s universal in both directions. Mainly for testing since ultimately you want to steer traffic. My guess is that a lot of the users are ignoring the steering and just using a talk group of one. I’m pretty sure you can set your radio up to ignore the incoming talk group and only qualify on NAC.
