The KB6HOH-12 VARA Gateway on 3570.000 kHz is useless due to QRM interference
from multiple WSPR signals in the range 3570.000 to 3570.200 kHz.

WSPR frequencies have been published and used for many years.? Putting a gateway on top of WSPR would be like putting a gateway on top of the FT8 frequencies.

Yeah, that’s too low a frequency to put an unattended automatic station.

Dave,

Why do you say that the frequency is too low for unattended use.

I am planning to setup a Trimode station that runs VARA/HF on 80 meters during the daylight hours.

Study the FCC Part 97:221 a-c carefully.

Automatically Controlled Digital Stations? with occupied bandwidth greater than 500 Hz must be in the defined ACDS sub-bands.

Automatically Controlled Digital Stations with occupied bandwidth LESS than 500Hz can be anywhere data is legal.

Attended stations, such as Peer-to-Peer, may be anywhere data is legal, and may be wide or narrow.

However, that makes the operation LEGAL, but it may still be un-gentlemanly. And, the particular station prompting this discussion is wasting his and others time. Anyone attempting to use that gateway is going to have constant QRM causing failure.

I don't see WSPR as much of problem with VARA though VARA will likely wipe a WSPR signal.? IMHO VARA should move since First Come First Serve or Early Bird Gets the Worm prevails.? Respectfully, Phil
