Replacing the RL1 Relay with a Magnecraft W67RCSX-12 Relay
|
Hi All,
?
The issue I had with the original RL1 relay in my FT-101 is that the meter circuit was not working due to the relay.? I had cleaned it a few times bit did not correct the problem but it made it worse.? I decided to replace the relay with a Magnecraft W67RCSX-12 relay as per written in an article on the Fox Tango website by Wayne N4YI.? (Thank you Wayne!)
?
I just completed the RL1 modification in which I replaced the original AE-3271 relay with a Magnecraft W67RCSX-12 relay.

The image below is my write up of what I did using Wayne N4YI article.

The original article was for a FT-101E, so I compared the schematics for my FT-101 (late, pre B model) to the FT-101E and found that Yaesu did not change the harness wiring for RL1.? After making the wiring change my FT-101 meter now works.? The receiver checked out and I did a transmit test by loading the the transmitter up on 20 meters into a dummy load and checking the audio modulation on one of my other radios.? It appears the mod with the new relay works.?

I am posting this info for anyone interested, but as a disclaimer you do it at your own risk!
