I operated Winter Field Day with a small group yesterday. The TX500 handled itself well.
There was one issue that came up.
I was operating 15m and another op was on 10m. I was clearly picking his signal up as if he were on 15m.
This morning I did some testing with a signal generator and I could recreate the situation.
I could clear it up by initiating the DIF function.
I could clearly see the small spurs that I was picking up disappear when DIF is engaged.
The only reference I can find in the manual is in the RECEIVER SETTINGS page.
It describes IF DSP, which I am assuming I am assuming is the DIF setting.
From reading it I take it that the receiver performs better with this function engaged.
It states that if it is disabled the radio has soft reduced performance.
Can anyone elaborate on this? Should I have DIF engaged all the time?
Why be able to turn it OFF?
