Menu #46 selects low frequency cutoff.? Menu #47 selects high frequency cutoff. Or, multifunction row "p", mash and hold the DBF softkey. Operating Manual page 30. 73, Mike N5MJ

Agreed on the difference it made.? ?I think I'll try turning it on and off in various modes to see its effects. Another learning moment. Dennis N1TEN? On Sun, Jun 7, 2020 at 6:59 AM, ROBERT

Re: AM Broadcast Stations Distorted
Sorry i thought it was posted.? Short version is the AGC was turned off and RF gain needed adjustment. Probably most of the problem was related to the AGC being off. Dennis N1TEN? On Sat, Jun 6,

What was the solution? I didsn¡¯t see it on here. I had the opposite problem when my mode mysteriously changed to AM while I was on FM. Bob, W7SCY Sent from Robert's iPad 2

Good catch! ? It was off. That improved signal even more than messing with RF Gain knob. Thanks to all for the teaching moment. Dennis? N1TEN

Re: AM Broadcast Stations Distorted - Found IT!
Gents, Thanks so much for your suggestions. ?? I just found out that the RF Gain was not right for the AM broadcast signal level.? I must have adjusted it during SSB operations, when moving from FM

Re: 857 stopped powering up; NOT a 12v source issue
Jason, I've had this with mine as well.? One instance was a sketchy fuseholder (the inrush current I-squared-R loss dropped the input voltage below 11.5VDC). Was the car running and VDC > 13 VDC at

Re: AM Broadcast Stations Distorted
Dennis, Check the receive bandwidth - AM broadcasts are often "wider" than SSB settings.? If I listen to AM I jack the low limit to 200 hz, and the high limit to 5khz. 73, Mike N5MJ

Re: AM Broadcast Stations Distorted
1070 kHz is on the AM band Los Angeles. Is it a typo or you are definitely saying 1070 is not on AM? Try listening to WWV on 5, 10, 15 or 20 MHZ on SSB and AM. Is the AM signal clean? If so, then
