Do you have the S9 reading on one specific band or multiple bands? I ask because I'm having similar noise issues but mostly on 40/20. Andrew, KD5CQ

Dan, NM3A, I'll try those settings in the morning and get back to you. NR (noise reduction) setting (menu 049) and NB (noise blanker) setting (menu 063) previously only had the effect of muddying the

Vic, WA4THR, I did due diligence concerning battery operation and examine the mains. I did get some results but not nearly as much improvement as I had hoped for. The Clearspeech or CLRdsp devices are

I feel your pain. I am in a HOA here in FL. I use my 891 for POTA and backyard ops. But I have powelines running through my back yard so my noise floor is high 24/7. So I too operate mobile with the

Have you tried the NR (noise reduction) setting (menu 049) and NB (noise blanker) setting (menu 063)? Also front panel menus MFl and MFp? I agree that finding and eliminating the source of the noise

On the radio display what is the S meter reading for the noise floor that you are experiencing? -- Compton VK2HRX Sydney, Australia

Of couse, the best is to locate the source and eliminate it. Some LED lamp supplies can be pretty bad, but it could be anything. You can try shutting off circuits one at a time while running the 857

At one time, I lived in a basement apartment, I didn't have ANY sort of antenna. I Bought an ATS-120 and a mount, installed it in my car and did my radio hobby from the car, not ideal, but I had fun.

Okay so I have a sub optimal antenna in a sub optimal environment full of frying bacon, embedded in a jet engine, under a waterfall, overlapped by 100 MPH wind noise. Yes it's a FT-857D with about as

Actually, even smaller is the "flip-chip" diodes such as HSCH9251. They are used up to 300 GHz. They are 7 mils long. You can't solder them - you're not supposed to. Instructions state the solder will

I did the same thing once but it was R1426. Lost FM which was working fine before I changed all 3 filters. Those are 0402 resistors which are VERY small (only 0201 is smaller).

Thank You for telling on yourself. You may not realize how useful this information may be.

Follow up.? ?All working normally now. None of the above suggestions made any difference (altho I never did check out the relay and capacitor on the main board.) Thank you for all your replies,

Funny. I just reinstalled my FT-857D in a newer truck. My screen was all zebra stripes. The audio was so low. I check wires and swapped external speaker. I checked the switch on the control head.

FT-857 service manual download. The d model sis also available for download. The control head is the same for both models. http://www.iw2nmx.it/Yaesu/FT-857/FT-857%20Service%20Manual.pdf

Tried exercising the jacks, but no change. Will look at contact resistances. Dan de NM3A at mail dot com -- 73, Dan NM3A
