Davie,

Get crystals and tune up per the manual. No mods needed, the work great on 6 meters. Almost all my repeaters, on all bands are MASTR II's.

You have found the limitation of using a Rangr radio. The radios only supports 16 channels stock. You can add the socket for another X2212 EEPROM and make it 32 channels...But...The 950/990 and 825/830 only support 16 channels per mode for the Rangr. The "dumb" control heads (S-550) or the...

I have used Link-Comm RLC1 controllers to monitor the operation of generators. Gives voice responses, can send quick call, and ID your telemetry station. They have both digital and analog inputs and outputs. Get an old Minitor pager or Plectron and use Quick Call to notify you of problems. Maybe the...

When in CLR, the squelch control will work, but no RX on the programmed channel. The TX lite will come on, but no output, checked with spectrum analyzer. The radios seems to read/write with the suitcase OK. The radios with their original programming do the same thing. I'm thinking that all I have is...

I have a batch of MPS radios here that are low split high band. They have some type of encryption or privacy module built into the back cover. Ther is a RJ45 Jjack for I assume a keyloader of some type. Switches on the top are channel guard and the other one is labeled PVT and CLR. Comb. # P9HMA The...

It can bo done. In fact, I used my MT1000 on 52.525 and 52.540 today. Had to make a codeplug with channels like 42.525, 42.540 and hex edit them to 52 MHz. Don't try to view the modified codeplug with the RSS, it won't like it. Just load hte file and program the radio. Sorry I don't remember all the...

Paul,

Glad to hear you got it to work!!!!

If you go the USB to serial route, be sure you the most current driver for the adapter. I think the only way to do this is to go to control panel>system>hardware>device manager> then select properties for the device >driver and then update driver. Be online so it can search. This took care of severa...

I have a Monogram here that I normally use on just one channel. Now I want to scan and cannot remember how to add and delete channels from the scan list using the front panel. I can change the default list with the programmer, but I think I can change it from the front. Anyone know???

Thanks,
Josh

I guess this is the right place to ask since Uniden is now owned by RELM... I forget the model of the radio, but it is newer production, VHF, with an alpha display. Anyway, it gets alternator noise real bad, especiallly in GM vehicles. The noise in the speaker, and not in the tx audio. Removing the ...

The old Selectone Mobilecall DTMF decoders use the X2212 chip in them. I managed to pick up about 5 or 6 of these units for a buck each at a ham swap. Just another application that uses the device, that can be found very cheap. Also, when one goes to upgrade a Motorola Syntor X9000 to 64 channel, th...

Maybe next time the band opens, I'll have my RANGR on. Any repeaters down your way I should program in for whe nthe DX is in? I only know 2 fellows tha ran RANGRs (100 watt) and they both burned up in a matter of days. Maybe the low power ones still generate the heat, but not enoug to smoke the boar...

What about the mods to the low pass filter to prevent smoking the PA? I have been playing aound with both 163 and 139 radios. Both will work to around 53.5 for tx and rx. Fine for my applications. The 163's seem to need a mod on the TX VCO, the removal of a chip cap to get good lock from 39 to 54 or...

I was wondering how the CHP control head is programmed. The reason I ask is that I know how to program the standard model for use on my Delta or Rangr. I use the PC, RIB, and the cable that plugs into the DIP header. I think the CHP is different because the software I have for them is in my suitcase...

Thanks Eric!

I'll look for it and see what it's all about!
