I am looking for an analog display for the FT-101Z in excellent or better condition. ?Please send a direct message. Thank you. 73, Michael Smith, N4KZO

I am looking for a YO-901 Multiscope with the optional band scope, all in excellent or better condition. ?Please send a direct message. Thank you. 73, Michael Smith, N4KZO

Thanks Jim for your help! I fully agree with you, that's the obvious way to go; I only quoted the transistors because I believe this is going to be the main source of difficulties (substitutions,

The next step SHOULD be troubleshooting with test instruments (and your eyes) to locate the defective part(s). Replacing parts just because they are there can lead to more problems than you started

Hi Joseph, Good luck with the repairs! There could be little information on the web as the TS-288A was not made in great quantities, and this is the first time that I have heard of a board that

Thanks Peter,?I really appreciate your reply! I was very surprised about the lack of any information on the web about that board. I even asked a few Swiss OMs, but somehow nothing came out!!! The

Hi Joseph, Attaching that schematic to my message didn't work as the quality of the image was degraded. I have placed a copy of the P04-004 schematic into the Files section of the group. The file

Hi Joseph, That is very interesting! The P04-004 is a valid Sommerkamp board number and is the IF board from the Sommerkamp TS-288A transceiver, which was the Sommerkamp version of the FT-101 with

On Ebay, someone in Japan has a lot of 4 slide switches for the 101 series, you might look at see if one of the lot is what you are looking for? Chuck N4IYQ

Hi Everyone, I just joined the group, and am already posting a question, hoping somebody would have some information to share... I just acquired (salvaged/got from somebody who wanted to get rid of)

Funny enough, I'm looking for the same thing. Love to know of sources without having to measure and search. Phil, VE4STG

I'm looking for the slide switch labeled in the schematic as "S8 - SLE12301". This is for the P.O./I.C./ALS Anyone know of a replacement part number or would happen to have this part I would be very

I double-checked the scope settings and found I had the wrong measurement selected. The actual output of the 78L08 is just a hair over 8V, and the switch, Pre-Mix Local socket and the board itself

I'm trying to diagnose a problem with the higher bands where the VFO display will change to random frequencies while transmitting. Specifications for the PB-2153 are 300mV output on Pin 3, where I am

Rewiring the RL-1 socket is not something I want to do; but the Potter & Brumfield relay is so tantalizingly close to what the FT-101 uses... Luckily for me, my OM likes to make electronic gadgets

Thank you Jim. That sounds very plausible. I’ll give it a try.

This sounds like an analog problem. You may be losing too much signal amplitude of the LO signal feeding the counter at the higher frequencies. Glancing over the schematic I think i would look at the

I still have a couple of issues remaining with the "Parts" FT101ZD I'm restoring. It looks like I have a frequency counter issue. ?The counter works 100% on all bands except on any of the 10 meter

Even after a careful online search and checking with my ham friends, I was not able to find the female Jones plug for the AC input to my newly acquired FT101ZD. ?There are six pin Jones plugs out
