Re: Need help
¿ªÔÆÌåÓýAre you using the same inline fuses in each scenario? Many users have reported issues with the fuse holders.?Tom k3tvc On Apr 27, 2020, at 5:19 PM, Carl Moon via groups.io <carl.moon@...> wrote:

Re: Need help
Check the fuses in the fuse holders

?Also use a volt meter to check the voltage at the power supply when idle and under load. Double check all connections. Yaesu also has Tech Support in Ca. Not sure of there hours with the virus. Good luck.

Need help
Carl Moon
I have had an 857D for quite a while which i have used mobile. At some point, I noticed some erratic behavior like screen flashing and someone reported my signal had a chirp and wasn't frequency stable.
So, I adjusted the menu so I could see the voltage reported by the radio. In RX, it looked ok; something like 13.5 or so. But when I keyed down in CW at 100 watts, the voltage reported by the radio display went down to 10.8. I tried making the wires feeding the radio larger, etc. with no change. I also tried it indoors on an Astron RS-50M power supply and note the same huge voltage drop. Power output is about 80 watts. Any ideas of what I should check? This couldn't be normal?? Carl |

Re: problem with pkt mode in 9600 baud
¿ªÔÆÌåÓýHello Miguel,
Ok... got it but a question for you.. when you say "isolated" interface.. is it something like an EasyDigi or Signalink?? If so, you're going to have deep problems trying 9600bps packet as most solutions use transformers that don't offer a wide enough signal on.
Two things here:? Once you change your radio to be "9600", you do realize it's now listening on the OTHER input pin on the 6pin DATA connector right??? This means you WILL need a different data cable going to your TNC, soundcard, etc.? Also note that unlike simple audio or Audio Frequency Shift Keying (AFSK) approach used in 1200bps packet, 9600bps uses audio to then trigger the radio to send the bits in a Frequency Shift Keying (FSK) approach.? FSK will sound like tightly packet hiss to a regular human ear: ?? #Listen to the very bottom one ??
I think there be four issues: ?? - you're using the wrong pin on the 6pin DATA connector ?? - the isolation transformers are hurting your signal ?? - I don't think the FT857's "9600bps" support is sufficient (most radio's 9600bps support isn't btw).? Negative reports: ????? - ????? - ? (view the cached version on say google) ????? - etc ?? - G3RUH 9600bps packet requires near perfect / full quieting signals with almost zero interference to work.? This usually means the other station must be very close, running higher power, and are using directional antennas.? When it works, it's amazingly fast but it's hard to get working.? Instead, consider running something slower like 3600bps or 4800bps packet using Direwolf or UZ7HO soundmodem.? Those modes are far more tolerant of radios and paths but .. yes, they are 50% slower. --David KI6ZHD |

YF-122S SSB Filter - New Design?
Here's a weird thing. So about a year ago when I was buying my umpteenth FT-857D I noticed the SSB filter picture on ML&S's site had changed:
I emailed them to say had they mistakenly grabbed a stock image or something or has Yaesu changed the design. Martin emailed and said they only supply official Yaesu parts and this was a design change, presumably because of Collins ceasing production of their mechanical filters. The CW and CW-N seem to still be of the Collins type. Other sites USA/UK I have checked seemed to have the old picture, either becase they have old stock or they haven't checked inside the box to see the change, or didn't care! Anyway, if you read the spec on the ML&S website, it still shows the same specification as the original Collins one, namely "10-pole Collins SSB Filter (2.3kHz/4.7kHz: -6db/-66db) for FT-817, FT-857 and FT-897." But I cannot see how it can be a Collins filter, it just looks too small for the SSB variant and if its not Collins, surely the spec can't be identical? It looks to me, more like a MuRata ceramic type, like the built-in one but mounted on a board like the 3rd party ones you can get nowadays e.g. Any ideas? I suppose I could email Yaesu/Yaesu UK, but I am not too bothered, Haydon Communications had stock of the Collins one so I purchased that. Just curios. 73 Mike M0SAZ |

Re: FT-857D Discontinued By Yaesu - Was a Great Run
Mike Parker
I was buying the parts in stages to cheaply get back on the air after having a 6-ish month break (I often buy new Yaesu rigs and sell them to fund another - but had a gap in the cycle). I must have owned at least 6, closer to 10 FT-857D radios since being licenced in 2008. I had a new YF-122C and YF-122S and had just ordered the TXCO-9 when I saw this thread. I went to ML&S and they had on the FT-857D product page they had just got their last batch ever from the factory, so I had to accellerate my timetable and manged to get one! So I am lucky to have one of the last ones of the production line and as this radio will certainly go down in history as a classic, I will never sell it.

Re: Delayed RX after TX
Hello everyone, Re-soldering the relay contacts did not help and when listen to the noise and kick the relay, the noise become attenuated and come back within a minute or less. It looks like that there are some internal contact issue in this relay.? Just ordered from Conrad SY-12W-K relays? to replace them. Also found same problem on 15m band but this relay is working more stable, showing the same issue not always. Any case will change it also.? ? ? |

Re: Connected Programmer Cable impairs CTCSS Tone Encode Feature
This is a know problem with the 857 and RT Systems programming cable.
It is mentioned on the RT Systems website in the knowledge base. See below.

Re: FT-857D Discontinued By Yaesu - Was a Great Run
Wish I knew that I could have ordered another 857 control head !? ?I? DID have to open it up and sort of cokes (sp?) the LCD into working better...
That said, I have two of the 857Ds so I'm OK for now. Bought a place near Phoenix, AZ so I bought an 891 for that house.? HRO there said that Yaesu did not put VHF/UHF into the radio because hams would rather have a separate radio for that and can monitor the two areas of spectrum at the same time that way. The little I have played with the 891,? I think I really like it though. boB? K7IQ |

Re: Delayed RX after TX
I had a similar issue and, as noted previously by other group members, it was caused by RFI in the mic holding transmit open. Here are notes from my maintenance log:
