[Alinco] DX-70 relay questions

[Tom Bates]

>>My DX-70 has developed an annoying habit of losing sensitivity during
receive. It's very irregular, the rig may operate normally for a while, but
occasionally after a transmission when it switches back to receive mode the
sensitivity is greatly reduced. I think it's a relay problem. It might be
more than one relay. Sometimes it's cured by turning the rig on and off a
few times, or tapping the key or the PTT a few times. The loss of
sensitivity is quite severe.



Hi there Al.  I had the same problem in my DX 70.  It was the "TR" relay.
Can't remember what the circuit designation for that relay is, but can look
it up in my service manual this weekend.  When I replaced mine, I'm pretty
sure I bought two of them--I'll check that too.  Is this that DX70 I sold
you a couple of years ago?

Regards,  Tom  -  AA1NZ
