Re: FT857D No TX only certain bands
Thanks guys, yep tried the relay cleaning?procedure a couple of times, will try again.?? The pcb boards seem secure, not sure how that would?affect?single bands? But worth a try.? Thanks for the tips, as you say, may need to the find the offending band pass filter and swap it out. Not something?I can do here at the moment, but still plenty of other bands to play on! Cheers
Pop the covers off, check that the PCB mounting screws are still tight, seems some rigs can work the screws loose.

FT857D No TX only certain bands
Strange issue just occurred with my 2 year old FT857D.? Rig operating fine on RX and full TX power on most bands but suddenly stopped all TX on 14Mhz and 10Mhz. Zero power out on all modes on these bands only. TX light comes on, fan starts but zero power out.
So far tried cleaning relays and hard factory reset.? No difference.?
Any ideas? Can't see anyone else talking about a similar fault.?
Unfortunately travelling in Europe with minimal equipment to test/repair.
Thanks for any words of wisdom..

Re: YAESU FT-857 Discussion Group - Digest #494
I too have an LDG Tuner, Z-11, Pro II. Some notes:
[1] I do NOT leave it on full automatic because it will sometimes retune in the middle of a QSO!! Not fun. I have it set on Manual all the time with Auto inhibited. Yes, it's a bit more effort but less work and faster than a full manual "Twin-T" tuner.
[2] I always power way down when tuning. The small relays inside the LDG will have tiny arc's when tuning. The more power, the larger the arc's, which could eventually make the relays fail. That has not happened and I don't have any hard evidence about the arcing. But when you switch an inductor, the voltage zooms.
Just my 2 cents!!

Sorry if this has been "asked-and-answered" but I've been through all the previous topics and didn't find a conclusive result.
I have an LDG AT-100ProII connected to an 857D with a homemade interface cable.
I can only initiate a LONG TUNING cycle with the [TUNE] button on the tuner if I manually reduce the power (menu 75) to 5 watts. The "tx request" function works through the cable but the power is not reduced automatically. I if I don't lower the power it just keys the radio for a few milliseconds and the tuner displays the OVER POWER dance \/ \/ -? /\ /\?
Is this a known "defect" or am I missing something in the config.
I can get the tuner to work in automatic mode .... switch to AM and key up till it's done ... but would like to be able to get the [TUNE] button functionality
Thanks!

Rob, If I remember correctly, you can set the radio to cut the power back but you have to manually key the radio if you’re using an interface cable with the LDG tuner. I think you also have to set the memory 085 to the TUNER setting. Check on page 14 of the LDG manual.
Unfortunately I don’t have my LDG tuner connected to my FT – 875 radio at the moment.

Correction,?
if you use the tune button on the TUNER, with the correct interface cable and power to the tuner, the tune button on the tuner will “Automatically reduce power, switch to the CW mode, and transmit for as long as is needed to complete the tuning cycle, and then will return to the previous operating mode in power level when done.”

You said: “?I have an LDG AT-100ProII connected to an 857D with a homemade interface cable.”
Has your tuner ever operated with your “homemade interface cable” as the manual says it should? ?I have the LDG interface cable and everything works as expected.?
I believe you also need to have menu item #85 TUNER/ATAS =OFF. All of the selections on this menu are for Yaesu ATAS antennas or AH-30 antenna tuner.?
See if you can borrow an LDG interface cable to test the FT-857 and AT-100ProII tuner. If they don’t work then, I’d check try to substitute a known working tuner.?

Re: Uneven power on HF bands.
Try the Radio on a 50ohm dummy load first? before getting any further?
into this discussion . You could have anything from a Plug to a relay to
and SWR unit in line causing a minute amount of + or - j being seen by
the Rig .

Have you set the menu on the radio to use the MH-59A8J? It’s menu 059 and needs to be set from NOR to RMT before plugging the MH-59 in.
?
Also, the MH-59 is a hot mic compared to the default mic. For it to sound good, you need to run through the ALC adjustment in the manual (page # differs between manual versions). For my voice, after going through the ALC on the MH-59, my
SSB Mic Gain went from 50 to 27, and AM/FM went to 25. I also dropped the PROC to 30.
?
For FM I set it to 27 after performing the ALC adjustment and used friends on the local repeater to help me tweak it. It was close with 27, but I got the best sound at 25. I set AM the same, but I don’t use AM, so it really doesn’t matter.
?
The MH-59A8J is a really good sounding mic once configured. After doing the ALC adjustment, I regularly get unsolicited comments on the high-quality sound on my audio. I have also been told I sound great for a mobile station. All of this
only after I added this mic.
?
I have a ham radio website that has a lot of information I have collected for my rigs, hoping to help others out. It is outdated, and I am hoping to rebuild it in the next few months, but there might be info in there that can help. The
downloads such as Chirp are way outdated, so it’s best to go directly to their websites rather than download the installers.
?
Hope this helps,
?

I've gotten complaints that the audio pitch is too high , is there a way to lower the pitch . I am using the MH -59 A8J mic.

Re: Uneven power on HF bands.
The first question is are you measuring
this into a dummy load or into and antenna?? If memory serves me
correctly, you will see a bit of power drop, into a dummy load on 12 and
10 meters, probably between 90 - 95 watts maximum, in CW with key
down.? This is normal with most? solid state radio these days.? I think
my 857 gives me around 93 watts on 10 meters.
