Good morning....does anyone know what the plastic rivit like fixings for the lid of the 301 are called> I kneed to have 4 replacements for my rig here in the UK. Seasons compliments to By Dave smith (

I will put my notes here for trouble shooting. J10 good radio.? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? bad radio. pin 3-4? ?7.6 k? ohms? ? ? ? ? ? ? ? ? ? ? ? ?103 ohms pin 4

Amp connector pin 4 (tx13.5) goes high to 13.5 volts when attaching a known good amp. Pin 4 on bad radio measures 45 ohms to ground and on the good radio, it measures 7k ohms to ground. there is no

Need one front panel knob such as used on the band switch and others KL7AM

Removing and reseating plug in boards and a de-oxit treatment of switches and controls has cured the issue!Next thing is checking why output power is a little low. I am showing about 85 watts cw on

I would look closely at the VFO/EXT function switch and wiring for continuity.

Well, I have all the crystals on frequency and still have a counter calibration error. It is less, like 1.7 khz with the pot turned all the way to the left. the marker frequency is spot on. that

I have a 301D with the outboard VFO and neither vfo seems to function, I haven't found a schematic that shows how the external vfo output is switched into the radio. Is anybody familiar with vfo

If it’s any help, I recall having to change a trimmer capacitor to a series cap. instead of parallel to pull a crystal which had aged out of limits. Extra parallel capacity will pull it down, series

You are correct !!? 40 meter crystal is 4 khz off and cant get it any closer to 21.5 mhz

It looks to me as there are trimmer caps for the band crystals?

schematic shows calibration pot as 5 k. It measures 4.88k. ..? resistor R14 to ground? schematic shows 1k, I see? marked 820 ohms and measure 798 ohms .. resistor on top side of pot? R15 schematic

On the front of the radio there is an adjustment pot and it is maxed out all the way to the left. That pot works. I don't know of any adjustment for that inside of the radio.

Did the VFO pot adjustment work Bob? Gene

My calibration adjustment is maxed out but the display is 2.5 khz off . what should I look for to repair this. Is there a adjustment inside other than the small knob on the outside? Would the 5 volt

I don't know yet.

Have you found any possible cause?? Mine didn't do it until I pulled the LED board out.? Found out I didn't need to do that to change the LED's as they're socketed (unfortunately I found out AFTER

Hi Forest.? I'll try that.? Any idea about the freq not changing all of a sudden after I replaced the readout board?? And do you know the Ebay sellers ID of the fellow in Italy that had the

Try adjusting the VFO (triggering) resistor in the VFO compartment. It’s a small pot that will stabilize the readout frequency. My readout kept flickering at the tenths of kHz and this adjustment
