Re: Ft-101b. Resistor R12

 

Yes..
I think if you look at the characteristics of this wire, it might work..
?

?
CW VOX not keying transmitter

 

Good afternoon group.
?
I am still becoming familiar with a new-to-me FT-101E.? I am a regular CW operator of both new and old hybrid Kenwoods, so understand the basic principles of CW operation.
?
My issue is that I can't get the radio to transmit when in CW & VOX mode, short of flicking the MOX/PTT/VOX switch to MOX.? If the mic is plugged in however, a clap or other noise trigger activates the VOX and it switches to TX despite being in CW mode.
?
I have tried the following:
  • Unplugging the mic.
  • Check the keyer continuity at the key plug.
Some questions to help further diagnosis:
  1. Should the radio emit the side-tone even with VOX isn't enabled (the switch in the PTT position)?? As it is I get no side-tone regardless of settings.? If so, it suggests the issue may be the jack on the back of the radio.
  2. Are there any common issues with these radios and areas to check with respect to CW keying?
  3. Any further tests you can suggest to further narrow down the issue.
Attached is a photo of the rig face, just in case I've got a setting wrong.
?
Kind regards,
? Lance, VK7TO

You mean this one?
Re: Ft-101b. Resistor R12

 

Hi Kevin,
?
I would like to know too!??
?
If I had to guess, it would be nichrome resistance wire which is non-magnetic, but that is my guess.? Hopefully someone in the group that is familiar with R12 will fill us in.

Hello,
I have to replace the 6:1 Ball Drive in my Yaesu FT-101E , produced by Mainline Electronics Ltd.
Does anyone know the exact model? and code for this replacement?
Many thanks,
73 de ?IU1AHB, Roberto
Re: FT-101ZD Tubes

 

I will check into the tubes, Jacques, thank you.? If the relay has to be changed, rewiring the socket will be much easier to do than with the older 101s.. finding a socket that will fit the opening in the chassis might be a problem though. Good to hear from you Jacques.? 73.

Thankyou Jacques.? 6883B is a far better price and not much re-wiring to do under the final box.? Now if I can find a source for the relay; several places the relays are listed but no stock.? I will keep trying. Nice transceiver, I had never had my hands on one until this one came in for repair. 73

I guess you guys know this, but I was told the 101 output tubes are the sweep tubes used in the old tube TVs. ?I suspect it was a smart move as Yaesu probably figured these tubes would be around for a while.

Just a note to ask if anyone is using 12 volt versions of the 6146B tubes in the "ZD"??? The 8298As have served well but getting pretty weak.

WOOT!!!!!!!
?
Diodes have been replaced....what a chore that was. And the radio is receiving again and, more importantly, not popping capacitors! ROFL.?
?
However, it needs more work and I believe discretion is the better part of valor at this point in time. I am going to reach out to Lee and request his services.?
?
Some things are better left to the professionals. Besides, I did replace all the caps, and got it back working again with a nudge from Lee. I'm gonna take a victory lap and call it good.?

Dave,

Lee had me check the diodes on the rectifier board (PB-1076B). Both D6&7 were cracked. They control the 13.5vdc circuit. So, replacements have been ordered. Hopefully this will fix the problem and this rig can be back up and running again very soon. ?I checked all the other diodes on the board and they all checked out good.?
?
Thank you again for Lee's contact information. He was/is very quick to reply and I greatly appreciated that!

I have run out of ideas at this point as to where the problem lies with the 101B. I'm at a point to where I need someone a whole lot smarter than I to resurrect this old lady.?
?
I have reached out to FT101repair.com but have not heard back from the gentleman and am wondering if he still repairs 101's.?
?
Soooooo, If anyone can recommend a person that does repair them, I would be grateful for their contact information. I so very much want to get this radio back on the air.?

I was so close a week ago and now much further from the end than the beginning.?
