Hi, All of the sudden my ft857d won't power on. I already checked. Front Panel is OK. Voltage is OK as well going into the board inside. Any idea what went wrong? Thanks, Edward 4F1OZ Yahoo Mail: Search, organise, conquer

While driving yesterday and monitoring my 857d, it randomly performed a factory reset without any input from me whatsoever. I contacted Yaesu and they asked if I used CHIRP to program it and they indicated that can cause problem, even years later. While I did use CHIRP to program, it was about 5 years ago and have had no problems since then. Has anyone else ever experienced a random factory reset like this? Any other potential cause? Tim K6TW

I have a Heil Traveler that I used with my ICOM-706 (since sold). Worked fine there, but made up a wiring adapter for the FT857 but no TX audio. Everything else fine including RX audio, PTT, up and down. The only thing I can imagine is that the mic element needs power to run thats not being supplied. Yeah, I know I could just buy a HSTA-YM adapter but I dont want to buy it just to troubleshoot and there is some satisfaction in making my own. Should I be doing something with that 5V sitting on pin 6 of the FT857 RJ45 connector? Mike WB1AAT

Dears, I wish to all of you Happy Holidays and healthy year 2025! 73 de Petr OK1RP

I've had variants of this problem where on power-up, the panel either does not come up, or flashes on and off. Today the computer was up before the radio, but that may or may not be a factor. The power button may not even work and I need to disconnect the power supply. I can always recover full operation by disconnecting antennas, digital cable, and CAT cable. Seems like all must be disconnected but there might be some combination that also works. After disconnection and reconnecting the power supply, press of the power on button and the radio comes on normally and works normally for hours afterwards. Any ideas?

Is there a plug-and-play method, system, or device available for the FT857? I'm moving from a home we built 17 years ago on a rural 5 acre plot into an apartment in a small city. My son lives 10 miles away on 10 acres. We have measured a couple of locations for trap 80-10 or 80-40-20 dipoles. I want to put my FT 857 in his workshop, connected through a remote device to his wifi and then connected to my end through the Internet so I sit in the apartment and operate the FT857. At my age, I'm just not into spending days tweaking this and that and the other . . . just looking for a simple plug-and-play interface . . . fi such a thing exists. Thanks.

There is an undocumented control pathway for the FT-857 and FT-897. The radio can be controlled by command signals received through the microphone jack once the menu 59 setting for the microphone is set to CAT. This may be useful to people devising mobile control settings for the FT-857. There are several schemes posted on line for making use of the microphone jack in a variety of ways to receive serial commands to control various functions of the radio. Tom Horne

I need to replace the whip on my Atas120a. There are two screws holding the whip in place. Can anyone tell me what size wrench I need in order to loosen the screws. Thanks Andrew KD5CQ

All, If you are not aware there is a free Yaesu FT-857 memory programming software by G4HFQ (silent key). This used to be a pay version of the software but since he is a silent key they have made it a free version. You still may need a license key but it is freely available. Lots of other Yaesu software here as well. https://www.m0lxq.com/g4hfq/download.html best N7KBC dwight

I have an older FT-857d. Recently, the radio stated coming on in VFO mode when in was in memory mode when turned off. Did a bunch of searching but have not found anything on this issue. Ideas anyone ? Thanks. 73 - BILL KA8VIT

Question: Can the FT-847 DSP Board be used on FT-857? If yes...how? Thanks for helping.

Can a japanese version 857 be modified full tx coverage and 100w ? I tried to open one, but it limited the power to 10w. Regin, OY1R

Hi all. In need of the Tech supplement for the later series PA Deck on the 857D with the MosFet for the V/U Final. If anyone has it. I checked the files section. Doesn't seem to be there. Unless I missed something. Thanks. Ronnie VE3NLS

Inrad 500 Hz mechanical CW filter #705-F has been listed for sale in numerous ham gear for sale. Find it, if is still available.... hihi -- Rafael / NN3RP

When using menu 75 to set the output power level, I've noticed some odd results When it is set to 5W, I see miliwatt power on 2 different meters (LDG FT & SureCom 102 HF) When I increase this setting to 10W or more, the expected power output on the meters match what I expect... Not sure why the radio seems to be doing this. The radio has the Collins 2300 Hz SSB and 300 Hz CW filters installed. I've also connected the SureCom meter to my base rig (FT-710) to confirm it read power correctly at 5W, and on that radio it is fine. Any suggestions ?

I have a Signalink with a Data Cable and CAT Cable connected to the FT857 - trying to TX from Winlink / Ardop. The CAT cable successfully (automatically) switches Band and Frequency when a Channel Selection is made. I tune successfully by way of CW key - with Red radio TX light showing, and the crossed-needle tuner shows Power out, and I tune down to 1:1 SWR. The radio works fine. Upon Start command from Winlink, the Signalink device clicks on the PTT light, and the Ardop waterfall shows a brief TX waterfall gap. The FT857 Red TX light turns on during the TX. HOWEVER, there is no Power Out from the rig going through the Tuner. This is perhaps an internal FT857 Menu Setting, but I'm unsure which one to adjust. It COULD also be on the Windows Sound side, but that seems to be functioning appropriately. The Playback : Speakers : USB Audio Codec indicates "Ready" . When the Signalink is sending to the 857, the Windows Playback Tab Output side indicates a few Green Bars of output. I would appreciate ANY input - particularly from someone with a functioning Winlink/Windows/Signalink setup. Thank you, Kevin VE7KHI
