I think this is absolutely the best group of people on this site. I have learned so much from the information posted here. Thanks to all that have helped me iron out issues with my equipment. Wishing everyone a safe and happy Holiday season!

I have a RCI 2990 that when it is in USB mode the noise level signal is about 3 s units higher on the meter than when in AM/FM/LSB mode on any frequency. From everything I have read the noise level signal reading for LSB and USB should be fairly close so I am assuming there is something up with...

Needing someone with an Original RCI 2970 that can help me with some physical wiring/circuit comparisons. I am working on reassembling one and need to verify 100% where the smaller red and black wires from the amp connect to the radios main circuit board. Needing pictures of both the...

I'm in need of a couple of parts for a HR2510 radio I'm attempting to restore and thought I'd ask here. These are the part numbers/description from the HR2510 Service Manual Y301 - BYYY0548001 Ceramic Resonator YY-548 CSA2.000MK (Blue 2 Pin Ceramic Resonator 2.000 Mhz on the CPU/PLL board)...

I have an RCI 2990 that has very low receive. I can hear strong stations yet there is no signal on the S meter. When I key up a radio on the bench beside it I get signal on the S meter but it's not pegged out and adjusting the RF gain doesn't do anything, S meter stays in the same place. I have...

I've had this mic for a while and finally got around to fixing a no audio issue. Thought I'd share some pics as it's one you don't see to often. It has a the option for a short 1kHz "End of Transmission Signal". Offers Vox compatibility for radios equipped with Voice activated switching and a...

I have a 142GTL with no transmit or receive. Radio powers up. Can key the mic and the transmit light come on but no rf out. I have checked the voltage on pin 6 of the PLL and have 8.25v. Pin 8 is reading 10.238 MHz. There is rf voltage at TP1. There is 4.8v at TP9. The problem seems to be in...

I picked up a Gray 150 A amp that has a burnt inductor/choke on the input. I am trying to determine the value so I can replace. The only schematic I have been able to find for this amp is on CBTricks. http://www.cbtricks.com/Amp/gray/150/graphics/gray_150_sch.pdf It seems to be a redraw and...
