Thanks Nomad, Thanks Nomad, anyone by chance have a clear schematic for this radio the one on cbtricks is blurry and hard to see. Also I looked at the Allignment procedures and was wondering if they are correct? I didn’t try to adjust anything I was more interested in the voltages and...

Radio receive is good all modes. Green power lite indicator on front blinks low to high. I can see some modulation on the radios meter in AM only, I also hooked scope to output and verified have modulation on AM but nothing else. Radio has NO mods is 100% factory. TP7,8,9 I see 6.3vdc RX &...

Guys, does anyone have the 11 meter mod for this radio? Drew

What controls the squelch power? I don’t get any fluctuation in voltage when I go from 0 squelch to full squelch. It’s like the squelch is on full all the time.

Ya nothing at all I checked to make sure external speaker jack wasn’t bad and it’s good. No sound at all or movement on meter when I inject a 1kHz 0db signal on any frequency I’ve tried a few.

Just checked both was with another radio as receiver and with frequency counter. Sounds great in AM not perfect in LSB or USB but not bad in any stretch. Frequency is spot on in AM on counter.

No noise at all with no antenna, volume 100% and rf gain 100% in all modes

Ya I’m getting modulation and some power out. Any help trying to follow the 8v switching T/R circuit that you might be able to tell me? Known test points to look at? Drew

It is a 15 board, I’m not sure it’s the amp because it has no receiver. I put a meter onTP 7,8,9 and in SSB I’m seeing 11.7 - 12.8vdc On AM I’m seeing 3.75 - 7.65dcv Thanks for your help Yes I may have had an old thread but was away for 4 months and thought it may be better to start clean. Drew

RCI-2995DXHP No receive on all modes & when connected to load on USB Signal Meter goes to S9, LSB S3, CW S4. AM FM & PA S0 Unit is only putting out dead key 2.5w and 28w modulated on AM, USB & LSB 26w modulated. That’s with amp in line, when I pull the J22 amp key I’m seeing 0.3w dead key and...

103 capac I was going by this: A capacitor code of 103 can indicate different values depending on the type of capacitor: Ceramic disc capacitor A ceramic disc capacitor with a code of 103 has a capacitance of 10,000 pico Farads (pF). The first two digits of the code, 10, indicate the first...

Guys I found C54 on my radio is NO GOOD and I'm not familiar with SMD type. I see on the schematic its a 103P. I'm just not sure what to order from Mouser or Digi Key? I believe it's a .01uf 10V 0% but not sure on size or if I even looked that up correct? Crambone

Thanks I didn’t forget you I got shipped out for a month

Not so adept on following schematic any suggestions on a starting point and path to follow?

I was using my SR-955HP and it just went almost dead. I tested Q25, 45, 46 & 47 and they tested good with a cheap Chinese tester. Since I had the desoldering I just replaced them all with IRF520’s. I’m seeing the following voltages on them. Any help would be apreciatted. Q25. G. D...

Thanks I appreciate it

Anyone looking to get rid of a Robyn SB-540D let me know or if you know anybody ? Drew

Thank you!

I’m looking for the measurement for the 2 screws that hold the internal board / strip in at the bottom of the base? Center to center
