Nothing like watching Buddy go through one of these radios and bringing it back to life! Thanks for the post!!

I watch your video with a lot of interest. Thank you for doing it. I recently acquired a TS940SAT which has a broken RF Final unit; I’m trying to figure out how to go about fixing it. Since the new PA board is elevated by the new, additional copper heatsink, washers or stand-offs need to be used at its 4 corners and 4 additional mounting holes else the board might be bent if the screws are over-tightened. At minute 24’, the thermistor wires are cut and there’s no longer a thermistor hooked up to the fan control circuit (IC1 and Q7, Q8 on the LPF unit board), I suspect the cooling fan is permanently disabled.

I used to have a Kenwood 430S but gave it away when I got my new Yaesu 991a. Love my Yaesu. Cheers from K9POW in eastern TN

interesting about D51, it also lights in my Radio and it works fine, I saw that glow and thought it was a LED in an early special package so never checked it farther

Thanks for the video, I have always enjoyed using this series of radios, I have owned my TS930 since the mid 80s. I must have thousands of hours on it.

Woo hoo, a Labor Day Buddy video. 😎

Awesome video Buddy. Always a pleasure to watch your videos.🙂👍

Buddy if you look at the picture of the board on the heat sink it tells you the black washers are for spacers 👍

Thanks for showings the install Buddy...I've replaced the power supply in my 940 along with all the other updates...been waiting on the PA board just 'cause the radio isn't on the radio bench anyway. Look forward to see how you resolve the issue(s)! 73 - Dino KLØS

very good, thank you

The carrier board

D51 appears on page 20 of the service manual in Figure 12. Looks like it is in the ALC circuit, specifically the area that drives the meter.

eliminates all the filtering. Should work great!

It's a shame about the PA transistors for I have 20 of them made by ECG new in the original packs of when I ran my Communications business. I'd be willing to trade for some repairs.

The new RF Transistor is not MRN101AN it's MRF101AN they cost about $27 + shipping from Mouser RF MOSFET Transistors Wideband RF Power LDMOS Transistor, 100 W CW over 1.8-250 MHz, 50 V

Is this radio really worth the new parts and repair costs which exceed its initial price?

Hi good evening, I have a Sony CRF-320, could you review and align it for me, I'm waiting for your response, thank you.

i have 5 of those radios and none of those work 😭

I put my money on the coax from the rf unit being in the wrong place
