Thank you Arman for coming back with
solution, something to keep in mind (or somewhere on the
computer).

Hello everyone,
Just for information to all that have the problem. I have found
the source of the problem. It is a faulty relay in a power
amplified board. In my case the relay was the one that switches
RX from GND to antenna for 20m band.
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.

CTCSS or PL Tones do not transmit

CTCSS or PL?Tones do not transmit
This will happen if the cable is left connected to the radio and is NOT connected to the computer (it sets up a ground loop that causes this problem).
Solution, disconnect the cable from the radio when it's not in use. ?
Note: ?If using control software that requires the cable to be connected to the radio AND the computer, this is not a problem and everything works properly. ?

Hi Peter,
This is not the case. I have removed all possible RFI from mic by using caps soldered to ground.?Also transmitting with 5w only also causing the issue.? In my case transmitter stops transmitting normally. The issue is with receiver, that does lowering the gain on transmit and restoring the gain to previous stage with delay when transmit stooped.
Thanks,
Arman

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.

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:
- On 10M FM above 35 or 40W (and possibly other bands and modes), the transmitter will not stop transmitting for several seconds or longer after the mic button is released.?Resolved. This is caused by faulty MH-59 mic design. Problem could not be reproduced with original MH-31 mic.?Modified mic by jumpering over ground pin inductor per instructions found googling. This resolved issue. Also made some transmit audio improvements to mic as found on Internet.

Connected Programmer Cable impairs CTCSS Tone Encode Feature
There have been a few threads on this issue, some inconclusive and some resolved. I am creating this thread to provide all the information in one place for the problem and resolution as I experienced it.
PROBLEM: Radio is properly configured for CTCSS tone encoding while transmitting but the radio can not raise even strong nearby repeaters that require tone encoding. Transmissions not requiring PL tone encoding are fine.
BACKGROUND: I had an FT-857D sitting in a box after being removed from a vehicle prior to sale 10 years ago. I recently installed the radio in the center console of a Jeep TJ where the factory subwoofer and amp used to be, with the control/display mounted above the rearview mirror. (The vent for the speaker leaves a large opening for cooling and I drilled some holes low on the opposite side for flow-thru ventilation.) I installed an original ATAS-100 antenna for HF/6M, and a Diamond SG-7500 for 2M and 70cm. Both of these antennas were also on the prior vehicle and stored for 10 years before this reinstall. After the install, SWR and transmit capability were good on all bands but I could not access any FM repeaters requiring CTCSS tone encoding on any band (6M, 2M, 70cm).
TROUBLESHOOTING: I used my Uniden SDS-100 scanner¡¯s ¡°Close Call¡± and CTCSS tone decoding capability to observe what the FT-857D was actually transmitting. The transmitter radio frequency was correct but the encoded PL audio tone was not. While configured for a PL tone of 100.0, 94.8 Hz was actually encoded. I tried a few other tones and, oddly, they did not encode at all or maybe were at a non-standard tone the scanner could not identify. So clearly there is an issue with CTCSS tone encoding on my radio that I did not have 10 years ago when it was last installed and used.
RESOLUTION: Google searching revealed (from this site and others) that increasing the CAT Rate setting (Menu #19) might solve this problem and that this issue might be related to having a programmer cable installed. This is the ¡±Ah Ha!¡± moment. Because the radio is mounted inside the center console and not easily accessed, I permanently installed an RT Systems USB programming cable attached to the CAT DIN interface, with the USB and excess cable in the storage box atop the Jeep center console for easy programming updates. (As an aside, I also wired the brown ¡°low power¡± wire to a grounded push button switch in the storage compartment for convenient all-band low-power enablement.) I did not want to pull the center console out again to verify the programmer cable is causing the problem. But simply changing Menu 19 CAT Rate to 38400 fully restored proper CTCSS encoding!
I find it very perplexing that attachment of the RT Systems Programmer cable, even with the USB end disconnected from any device (and power), renders CTCSS tone encoding unusable. But I am happy that I can now access my favorite repeaters in my Jeep.

Thanks for the tip Arman, if the RF problem comes back should I choose to use that MH36 mic?again I will give your fix a shot

Hello Mick,
I was having the problem with RF getting into microphone. Currently using microphone MH31 with installed BX-184 kit into it with Heil HC-5 microphone element.?So the issue with the RF making distortions in microphone was really annoying. But I could fix this issue. Just solder 220-270pF?caps from microphone terminals to the ground and unwanted RF will be filtered to ground allowing AF to pass to the radio. For now I do not have any unwanted RF in my microphone. You can modify in this way all AF or switching lines in microphone cord to remove all possible RF in the wires.?
But the issue I am having is like delayed and step by step coming back receive sensitivity. It is more looks like the AGC restoring RF gain? to initial after a strong signal on the input, but takes longer. And this happen only on 20m band.?

my 817 and 100watt amp does something similar when I had the mic gain a little too high, it hangs for 20 seconds or so, turned the mic gain down and return to receive was almost instant, that was using the mh36 mic known for rf problems, with the std mh32 mic, the gain could be turned up no problem, so in my case it was rf getting into the mh36?mic holding it back from returning to receive even thou there was no tx light showing. mick, sa4mdn

Hello,
I also own FT-857D and having the same described issue only on 20m band. All other bans are working fine, just a some delay on 20m after TX or band changing.?
Any thoughts what is causing the problem? Have you solved this and fixed the issue?
Thanks in advance,

Re: FT-857D Discontinued By Yaesu - Was a Great Run
I like the idea of an HDMI port on the radio, drooling over the FTDX101MP.? I had my FT857 and FT8800 in my 2003 Silverado with the head mounted in front of the little pooka above the front window with the bodies under the back seat.? Moved the FT857 to a backpack and put the FT891 in the truck. Never did use the FT857 for VHF/UHF.? 73,? Buzz KD4CXI

Re: FT-857D Discontinued By Yaesu - Was a Great Run
I like the idea of an FT-857E -just use the FT-857D form factor and currently tested technology, but program-in the current 160 meter frequencies, install a more durable LCD display, AND add a HMDI port for off-the-shelf monitors/TV sets/projectors. /s/ Richard KI6MYJ.

I still have my 857D in my car (see ) ?but had bought an 891 to replace it.? When I found settings were not saved between bands (CW filter width for example) I sold it.? It's not a 857D replacement
Maybe they'll come out with a 857E ? ;-)? One can dream.

I would love to see a FT891 with 2m and 70cm added.? Not sure it is going to happen, though.? The 891 is an excellent HF/6m radio. Wish Yaesu would fix the software bug where the noise reduction turns off and the bandwidth resets to default with you change bands or VFOs.? You can get around the noise reduction turning off by using the tunable memories and using the MULTI knob like a band switch, but the bandwidth still resets to default.
