Regarding the issue of NR, I know this can be a touchy subject and most will

The logical cure for line noise is to notify the power distributor in the
area and ask them to locate the noise and eliminate it. I have had good
luck in this regard especially if you take the time to narrow the noise to
specific poles, etc.

The hardware setup to use both receivers in RTTY is simple, and no

Yes, if you're not trying to copy both signals at the same time (e.g.,
split RTTY DX), you can use MMTTY's ability to select Left or Right
to select Main/Sub without running two copies.
This is a good example of just how subjective improvement can be.
Sure, the hash is gone, but it's replaced by the underwater warbling
sound so common with highly processed audio.
Personally, I find that warbling variation in the audio far less pleasant
than the noise.

antenna receives only noise, the noise will disappear and only the
