[Elecraft] K3 Poor RX on 17m

[Chris Page]

GM Bill and many thanks for your two emails. 
First, yes the sub-RX also exhibits the same loss of 
signal. 
Looking back at my 2025 log (I am QRV every day) for 17m, 
the problem appears to have started at the end of January 
and was perhaps more sudden than what I first thought. Up 
until then I was having 17m QSOs (some with DX stations) at 
least every two/three days, but since 28 January, only with 
two strong European stations. So, please ignore my earlier 
remarks about the problem coming on gradually. I ought to 
add that I only run 5W CW QRP but this wouldn't affect the 
receiver would it? 
I cannot think of anything I did to the K3 around 28 
January, changing the settings, etc, that might account for 
the problem. BUT, just after I typed this (I am working my 
way through your email), I came to your paragraph about the 
KXV3 module and, lo and behold, that is what I must have 
done - accidentally pressed the RX ANT button while on 17m! 

I hadn't noticed the RX on the display, probably because it 
was right above the PRE display that I had also switched in 
on 17m, and I (wrongly) thought it was one display of RX 
PRE. 
Thanks ever so much for pointing me in the right direction 
and a big feather in your cap for diagnosing the problem 
for me.
