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

I have a 301D doing the same thingKL7AM

Well, after buying TIL306's and TIL308's and replacing them, now I have an FT301D that doesn't change frequency.? Just sits on the low end of whatever band it's switched to.? (3.500, 7,000, etc.).?

Well, I have 6v but still neither the radio VFO or the outboard VFO work. The digital readout changes as it should with the band switch but no VFOI tried to measure the radio VFO output with my scope

Try mouser and look for a 6 volt LDO regulator. There is always a work around.

I read where Yaesu had a workaround for the TA7089M using the DIP version? and that would work for me too. Also a working PB-1436B IF board would work The radio powers up but the VFO doesn't work and

Seems to work. :-) Jim al7fs

i put google translate on my smartphone, selected japanese to english translation. pointed camera to text and out pops english !!

Problem solved. !!? Replaced mixer IC and a couple of diodes. RF board is now working

It takes time for the deoxit to work. now, this morning noise is gone. I tried to measure the output of the mixer Q101 on the good rf board with a scope and I could not see anything. Dont know why. I

pb1433 rf board output of Q104 board pin 14 going into t3 is a beautiful sine wave. output of t3 going to board input pin 15 is trashy noisy. I sprayed the band selector wafers with deoxit and gave it

Problem solved I have the vox board working now. I changed the circuit a little. Now, the MC14011 drives a 2n2222 which in turn drives a mosfet, 2n7000. It works very well now. Q606 is a 2n2222 and

I replaced the receiver mixer and receiver amp mosfets and now the receiver section works. for tx, there is 240 mv of rf output. input to q105 is 95mv. have to check the protection circuit now. SN7400

It was no rx.. didnot test tx
