Re: Schematic of the SMP-4004C (Image link fixed!)

I don't know if the schematic shows up for everyone else like it does for me or not (part of it cut off), but if it does, just right click on it, and select "View Image" to see the whole thing.

Re: The Radio Information Board Login

Alex, any idea how long new registrations will be suspended? I've got someone wanting to register.

Re: RELM programming adapter schematic

The RH256NB is a mobile radio. Its simply a newer version of the RH250/RH256 mobile.

RELM programming adapter schematic

Does anyone have the schematic of either the IA100 or IA4500 programming adapter? I'll also need the pinout to connect it to an RH256NB.

Re: KPG-4 Schematic

Does anyone who downloaded this schematic while it was still up, or anyone I sent it directly to, still have a copy? Due to computer problems over the years, I seem to no longer have a copy of it. If someone can send me a copy, I'll fix the image link so that it shows up again. BTW, do you have any ...

Bantam/Titan programming cable info

Does anyone out there have a schematic of the Bantam/Titan programming cable? The pinout of the mic connector of these radios, at least?

70-1337B parts needed

I need a power cable for this radio. Can anyone help me out? Used is fine, as long as its in good condition and the wires aren't extremely short.

TK-7180 programming info and part needed

First, what software and programming adapter do I need to program a TK-7180?

Second, I need an internal speaker for the same radio. New or used is fine, as long as its in good condition and works properly.

Re: KPG-4 Schematic

Due to some computer problems here, I'm not sure if I even have this schematic in an electronic format anymore. I'm pretty sure I have hard copy somewhere, but I'm in the process of rearranging everything right now, and don't know for sure where it might be. After things settle down a little around ...

Re: Another Ge Rangr question...

To update my problem, I've "padded" the VCO trimmer caps for a higher capacitance, and can now get the VCO's to lock at lower limits, but the bandwidth seems to have dropped off. I'm trying to run a split of 144 to 162, and it just won't quite cover that far. According to factory specs of a 20 MHz s...

Re: Another Ge Rangr question...

To revive an old thread: I have a 150-174 Rangr that I'm trying to mod for Ham use. I've adjusted the VCO's as far as they will go, and can't get the receive to lock quite all the way to the bottom of the band (app. 145.200 is as low as it will go), or the transmit to lock even at the very top of th...

Re: KPG-4 Schematic

I can send you a copy of the KPG-22 schematic if you'd like, but you'll have to find longer than normal phone plugs, and I have no idea where to find any such. Speaker/mic cables don't have the necessary contacts. If you'd still like the schematic, let me know.

Re: GE Phoenix Programming Help

Glad to hear you managed to find a solution. I never thought of doing it that way. It does sound a little time consuming if you're doing more than a few channels, though. I'm not sure how exactly it all works, but the little programmer I referenced earlier requires no conversion. Just give it the he...
