Where to start?
Hi, I bought an FT-101E "for parts or repair" on ebay. It's not here yet, but I need to start collecting data, manuals, etc. I bought an FGR-7 a few years ago which I completely realigned and

Re: 42 years for a dry joint from manufacturing to cause a problem!
Perhaps I can beat your 42 years now Gordon!. I've just had another dry joint on my early FT-101 (FT-277) fail after almost 52 years. I had been working on the radio on the bench and was just doing

Re: FT-101 deaf above 40m
Update - I’ve replaced the 20m crystal and it’s now working well! I have a question though. I’ve been aligning the clarifier and the tx/rx with the Zero adjust. I noticed all the guides online

Re: FT-101 deaf above 40m
Yes, by all means and there are plenty of YouTube videos on how to do that.? You can also use the probe with an analog voltmeter if that's all you have.? The manual wants you to shoot for 300mv

Re: FT-101 deaf above 40m
Richard thanks. No I don’t have any test equipment other than other radios receivers, DMM (not much use here) etc. I used a nanovna as a signal generator for the other bands alignment and that went

Re: FT-101 deaf above 40m
Hi Carl, As you've already discovered, the caps have just the two connections.? The right side is the rotor connected to ground. The small lead on the left connects the stator to the xtal.? Three

Re: FT-101 deaf above 40m
Ah yes noticed on the schematic, thanks. No 20 meters wasn’t working before. I tried adjusting TC18 during the alignment and first found it did nothing, then broke completely.

Re: FT-101 deaf above 40m
Carl, With the 3 leg trimmers, 2 legs are the same connection, the other is the variable connection. Was the 20m receiving before you tried adjusting T18? Regards, TF Sent:

Re: FT-101 deaf above 40m
Thanks Tony, this is what I suspected. I’ve ordered one off eBay so fingers crossed it’s a working one and it solves the problem. TC18 also shattered when I was attempting to tune the crystal

Re: FT-101 deaf above 40m
Carl, The 20m oscillator xtal X3 (20.02 MHZ) on the heterodyne crystal oscillator board may be bad. Regards, Tony VA7TF VE7ACF Sent: April 15, 2023 6:50 AM To:

Re: FT-101 deaf above 40m
Well I’m still no further with this. Every band working but for 20 meters. When transmitting a carrier at 14.250 on the 101s display my SDR showed the signal at 9.320. So I presume that’s where

Re: FT-101 deaf above 40m
Thanks Rob I’ll do that. I’ve managed to get every band working now other than 20 meters which will not align at all. In fact I’m hearing LSB signals around 14:400 and FT8 at 14:450ish! Could

Re: FT-101 deaf above 40m
Another thing is to take photos of each of the boards before you start so you have a reference plus only change one at a time making sure of the polarity.?That way you should not go wrong.? All the

Re: FT-101 deaf above 40m
It may be advisable to change the electrolytic capacitors. This can fix a lot of issues without having to realign. You have cleaned the band switch which is another common problem. Don't worry too

Re: FT-101 deaf above 40m
Well I’ve received the 101 today. The first job I did was to spray all the crackly pots including the band wafer. I’ve got 15m working so far. 20m is way way off frequency. I hear FT8 signals

FT-101 deaf above 40m
Hi all, new to the group. I’m about to receive a poorly 101 (original) tomorrow which I have been advised only works on 80/40m. It’s deaf on anything above those bands. Does it sound like a dirty
