Old 10 Meter RCI Radio Question
I have a Ranger (Mirage) 2950, this radio does not like the cold. This radio resets itself to 28.000 Mhz or, will turn on and be stuck at 31.999 Mhz until I go to the "Manual" mode and tap the transmit button.
CB Tricks says that there is a battery for the cmos in the CPU but, I do not see it; it does not seem to be accessable from the inside of the radio without removing the front panel from the display AFTER the display unit has been separated from the chassis.
I must be missing something......
I like this radio alot and, I am wondering if there is someone Trustworthy and reliable who has repaired RCI radios. I am looking for someone with knowledge of the quirks of these radios.
My service monitor / scope crapped out so, I am kinda like a row boat with only one oar in the water.
The CPU board in this radio is is the DPT295042z, the same boards are in the 2527, the RCI 2950, 2970 and, the RCi 2990. The CPU / PLL goes crazy and thre radio has to be reset to the desire operating frequency when powered back on.
The is no visibile battery backup for the CPU ROM so, it seems to be erased every time it is powered or or off.
this is the board
Dallas/Maxim and other IC manufacturers are actually placing SuperCapacitors and/or batteries within the RAM or uProcessor die itself!! You would have to replace the uProcessor or RAM!!
CB Tricks says that there is a battery for the CMOS in the CPU, BUT I do not see the battery
I have one here a fairly new RAM device that Dallas/Maxim sent me for testing -- replaces 3 separate parts and a lithium coin cell on the PC board (everybody wants a smaller device these days).
Since the parts list and PC board layout X-ray does not show a battery -- that would be my first guess. Planned obsolescence by Ranger with a specially made uProcessor?? Cross-check the uProcessor numbers. Possible!

Greg may be right on that.
I do know the EPT295043Z board has the coin sized battery mounted on the other side on the board. Right behind the CPU.
It is not very hard to get to.
You do understand that RCI junk is intended for the CB/Freebander crowd?
Oh please. They are garbage marketed to the freeband crowd that 10 meters is simply an excuse to try to elude the FCC. They are not intended for ham use, and a short Google search will confirm just what they are being used for.

What... you mean to tell me "real hams" don't shop at the local truck stop? They don't order their top-end radios from Copper?

junk? for some of us on limited incomes, its about all we can afford (and mine si strictly 10 meter thank you very much). for a "junk" radio it has a very nice receive (not as good as say yaesu or kenwood, but in a pinch it works nicely).

I purchased mine at a local radio shop (HRO didn't have any in stock at the time) and I probably paid about $50.00 more than I should have, but, its mine and it woirks.
anyway, calling a specific radio that is actually FCC type accepted for the US market as a freeband/11 meter radio when there are others specifically made for that market (and are highly illegal) is a farce. you want a freeband radio, try the cobra 148gtl-dx (24-30 Mhz with switchable banks) or the Thunder 2000fm (with 6 banks for 40 channels each plus FM mode) or a few others.... There are many others....
I wish I had the 700-900 dollars for a kenwood or an icom or a yaesue, but i don't. so I went with what I could get. you don't like it? TOUGH!.
funny, mine came from apollo communications and it was factory spec only. no mods. care to try that again?
