FT857 WL2K FM not working, HF works, FM works in other apps
Background: Winklink 1.6.2 on Windows 10 Pro 20H2, FT-857D using XGGCOMM Digimode 4 as soundcard/CAT control
This set up worked great on HF and FM as I've been doing Winlink Thursdays weekly as my New Years Resolution until a couple weeks ago. HF modes still work, VARA HF, ARDOP, as well as other nonwinlink apps (FLDIGI, JS8Call, etc.). VARA FM and Packet using UZ7HO sound modem also worked and now they don't. JS8Call on 2 meters also works in all the radio's operating modes (FM, DIG[USB], PKT). I've reinstalled both of the problematic FM modems, fiddled with every setting in the modems and radio I can find. I think this is a problem with the Winlink program itself but can't confirm. Any ideas? -K4SPB |

Re: 440 no transmit power
开云体育Hi Zack, ? Personally I think that the subscription to mods.dk is well worth it. I’ve been a subscriber for many years now and it is always great to be able to find all different manufacturers in one place, and the URL is easy to remember as well. ? I have also uploaded a few manuals to them over the years as well, which extends the subscription. ? 73….Eric VK2VE. ? From: [email protected] <[email protected]> On Behalf Of Zack Widup

Re: Replacing TOKO Ceramic IF Filters
I bought my FT-857 new and have never had the filter problem. It manufacturer info is: July 2003 Lot 10 #192 in lot 10 So it is not one with the problem rather one that had not had the problem (yet) Pat, WA3UOE On Sat, Mar 19, 2022, 1:17 AM Tony <73GUDDX@...> wrote:

Re: 440 no transmit power
The manual is available in several places on internet as a PDF file, free download. This is where I downloaded it: Zack W9SZ On Mon, Mar 21, 2022 at 5:16 PM Jeremy via <kd4kzz=[email protected]> wrote:

440 no transmit power

Is there a service schematic and troubleshooting procedure to figure out what has failed? I used to work on building/fixing radios/electronics and TVs back in the 70s when I first got my ticket but I haven't worked on these modern ones.? Barring not finding any info does anyone work on the FT-857d other than Yaesu? I've heard Yaesu service has recently been taking months to turn a fix around.? |

Hello all. I have an FT857. It is quite noisy, on rx, even with the antenna
disconnected. Is this an indication of the ceramic filter problem? (In RF not
SQLCH mode) Or, just what is the give away for this problem. My FT817 has a
better rx noise figure so, hence the question.

The FT-857D is being serviced at this
time so I don't have it in my possession. However, the FT-897D I
recently purchased has a date code of July 2007 and it has the
same ceramic filter issue. The rig was essentially new in the box
with the sticker attached to the display so it was never used. It
seems the defective filters degrade over time whether the rig is
used or not.
I contacted Yaesu about the ceramic
filter issue and the tech said he wasn't aware of the problem -- I
find that hard to believe.
