[1000mp] LF ad MF reception on a Mark V Field

[Bruno Tréguier]

Hello there,

Yesterday I browsed the low bands between 100 kHz and 700 kHz 
approximately (just wanted to listen to a broadcast program), and my 
antenna selector was on the wrong position, which I didn't notice at 
first, so the band was of course very quiet. However, on certain precise 
frequencies, I could hear a very strong QRM (S-meter going to S5 or even 
S7) like around 240 kHz or around 500 kHz. This phenomenon fades out as 
you climb in the frequencies, and totally disappears around 900 kHz. It 
looks like an internally generated QRM as it takes place even with a 
disconnected antenna. Maybe an internal clock which isn't adequately 
filtered ?

This is of course not a main concern as I seldom use my transceiver for 
that purpose, but just out of curiosity, has someone else experienced this ?

Thanks a lot !

Best regards,

Bruno
