Re: FT-101B Will not go into transmit with the mic or MOX switch
I bet its the switch, try using the other side of the switch that is not used, boom... works

Re: FT-101B Will not go into transmit with the mic or MOX switch
Keith,
I would make sure the contacts on both relays are not corroded and making good connection. I assume you know how to do that?
Does the 'VFO' red LED stay lit when you key?

Thanks Mike, I checked pins 1&2 and they are shorted.? I did pull out the other relay and it looked good, i didn't pull it apart.? When i key up or put it into MOX mode it sounds like it's still in Rx mode, I can hear the noise still.? I don't hear either of the relays clicking or engaging.?? KN6WNE Keith.?

Re: FT-101B Will not go into transmit with the mic or MOX switch
Sorry about that I put my call sign in my profile and thought it would be visible on my posts.? KN6WNE Keith.? I do have schematics, I'll check what you've written.? It won't go into transmit with the MOX switch engage either.? I replaced C13 like Buddy says to do in his youtube videos.? His channel is called the radio guy.? I'll pull up the schematic and start tracing.? The Mic was tested on another 101 and it worked.? Thank you very much Tony

Re: FT-101B Will not go into transmit with the mic or MOX switch
Hello, ? Not sure who you are. No name or call sign at end of your message. ? Download a schematic and start tracing from pin 3 of the microphone connector past the MOX switch. (Does the radio TX when the PTT/MOX/VOX switch is placed in MOX? MOX… manually Operated Relay.) Path then goes thru RL-1 coil and on. ? You do not mention you have a schematic. The “light bulb” acts as an RX fuse in case of too much RF injected into the receiver. Make sure it is the correct type bulb,it has nothing to do with TX. ? Regards, Tony F. VA7TF? VE7ACF ? ?

Re: FT-101B Will not go into transmit with the mic or MOX switch
Also check the other relay in the audio section (not just the antenna relay)
Make sure pins 1&2 on the accessory jack are shorted.That allows heater current to flow.

You might also want to post your query on the
Facebook group dedicated to the FT-101:
They have over 1800 members and plenty of experience to draw on.?
They helped me get my 101EX back up and running.
Good luck,

Re: FT-101EE component question
Ok I think I found the answer.
My manual, in Section 6 "MODIFICATIONS", page 6-21 & 6-22
describes a fix for "Hum Problems", and calls for the addition
of a 1000uf/25v electrolytic on T12 to ground (which is what I have)
So some owner in the past probably made this mod.

Perhaps some boards where swapped in the past.

I'm a bit confused in the manual where it tells what variation you have

Re: First visual inspection on my newly acquired Yaesu FT-101E. How's it look?
I've taken tube radios to the car wash, but a bit leery of doing that with the PCB arrangement in this case. Which is the only reason I didn't suggest that myself.
