I am "loosing" repeater offset

 

After initially setting and successfuly testing 440 MHz repeater access I subsequently loose the "offset" setting.
The little and hard to see -+ sign above "O" of "VFO" just goes away.
Mostly and at random (?) when I turn the power off / on.
The "offset" is set / alternate by pushing "RPT" .?
Since these mini sign are hard to read I also check? the main frequency display and it SHOULD change on transmit.

Is there option / setting I have missed to have the "offset" permanently? per frequency ?

Doug,

What is your callsign and location. I'm certain someone could help with the appropriate equipment.?

Re: Lost RF in middle of Tune

 

No I have not found the problem.? I dont have a watt meter so I cant try the watt meter and dummy load idea that everyone seems to say.? I am trying to reach out to my local club to see if anyone have one.? Thanks for checking.

I alwsys start at the beginning. First, take the tuner out of line. Hook the radio to awatt meter and dummy load.
Put it in the AM mode. With your power set to maybe ten watts. Key it. You should see 10 watts and 1:1 swr.
If you do, the radio works, you may have a tuner, or antenna problem.?
What antenna are you using, is it possible your antenna just isnt being "tuned" by the tuner, that it is just way off?

Doug, have you resolved your LDG tuner issue? ?My LDG AT-200Pro (connected to my 857D) has a similar malady. ?It has not been used for a while and I thought the relays might suffer from not being used but I can hear them click when I manually tune with the C UP / C Dn / L Up / L Dn buttons. ?No output on a cross-needle SWR / power meter. ?Antenna is a 135¡± dipole fed with 450 ohm and is tunable using another rig (KX3).

Lost RF in middle of Tune

 

I have my 857D hooked up into a YT-100 LDG tuner.? Now, when ever I try to tune on freq, I dont hear the relays clicking anymore and the the LED on the LDG flashes 4 times.? According to the manual that means that RF was lost in middle of tune.? So does that mean my finals are out in my radio?? Or something else?? Help.

857D LCD repair

Mike
 

I have two 857D LCD assembly's I have replaced I would like to find someone that would/could try repairing them as I have read that with the right equipment (which I don't have) the ribbon cables to the screen can be redone with some success.

Wanted FT857D LCD

 

AFTER you have replaced zebra striped LCD for your FT857
what are you planning to do with the OLD? one ?

Can you send it to me before you toss it into the? landfill ?

I''l pay shipping and reasonable "finders fee".

Private reply preferred.


Re: FT857D Replacement Panel Screen

 
Edited

I ordered from Radio World. Excellent customer service and received quickly to Virginia (by way of CA for customs inspection). Yes, desoldering the 4-pin connection was troublesome - I am not very good at soldering/desoldering. I went ahead and ordered replacement 4-pin connectors and the Pot/PC board assembly from Yaesu (pictured). The 4-Pin connector connects from the replacement board to the AF/Squelch Pot assembly. The pot assembly is easily removed from the face-plate with the typical knob retaining nut. Here are the Yaesu part numbers:
Description? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?Item ID? ? ?? ? ? ?Notes
Wire Assembly AH007M? ? ? ? ? ? T9207024? ? ? ? 4-pin wire assembly with connectors
VR-UNIT? ? ? ? ? AH007M00? ? ? ? CS2592101? ? ? AF/Squelch Pot with integrated PC board?

Yes, I ordered several spares knowing how bad I am at soldering...but it went very well.?


In this view - the ground connection is all the way to the right and is noted by a line next to it. Likewise, on the replacement screen board - the same - ground noted by a line. I connected with the yellow going to the ground connections.

If you look closely at the attached parts diagram - there is also a foam "Sponge Rubber" border that goes between the screen and the case - I ordered that too and used alcohol to remove the old adhesive from the window.

The parts were inexpensive and the entire transaction was conducted via email with
b.velarde@...

I 'killed her with kindness' and received relatively prompt replies and responses - but not much in the way of friendly dialog! No complaints!

With these replacement components - the screen replacement is super easy! I agree - seating the display board assembly back into the panel requires a bit of finesse but take it slowly and it will snap/pop into place. The 2 screws will properly seat the board and ensure the Select pot/knob works properly.

Hope this was helpful, 73, Howard, WZ4K


Re: Fuzzy white stuff on TOKO A55GV

 

I hadn't used my 857 for a few years and noticed constant static after powering it up. Sure enough, the 3 ceramic filters had the white crusties. I sent the radio to Yaesu in Cypress, California and they replaced the filters for less than $75 for parts and labor and about $25 for shipping. I bought a set of the filters to do the job myself but after watching a couple of YouTube videos on someone actually doing the work, I decided I wasn't confident enough in my soldering skills around surface mount parts to do the job myself. I also had them do a tune-up while they had it. The turn-around time was about 3 weeks due to the virus. Well worth the price to have it done by the experts. The radio works great now.

Script for mode 80 RFG/SGL

 

Does anyone have a script for Ft 857d that will run with DXLabs Commander needs to change menu mode 80 to SQL when in FM mode and back to RF Gain when in any other mode.

Re: 857 stopped powering up; NOT a 12v source issue

G0MBV
 

Try plugging the little separation cable in, (the supplied 4 inch one) just to check the longer cable hasn't got damaged.


Re: 857 stopped powering up; NOT a 12v source issue

Merlin, K3MEJ
 

I had this problem and contacted Yaesu. It's caused by low in rush current. I had to heavy up the power cable from the battery to the radio. My old cable some how lost its ability to handle the current. Merlin K3MEJ


Re: Scanning HF frequency standards of WWV.

 

You can¡¯t really ¡°scan¡± the WWV time signals since the scan would stop on the first one that breaks squelch and stay there, usually 10MHz. You could configure Scan Resume (menu 077 and 078) to let the scan continue but this would apply to all scanned channels which may not be desirable. Even so, do you really want to listen a few seconds of every received WWV channel every scan cycle through your channels?

I have all the WWV frequencies in consecutive channels and set them to NOT scan. When I am interested in propagation I just manually scroll through the channels. Of course, if your antenna is a screwdriver or requires a tuner, all of the WWV frequencies may not be in your receive bandwidth without retuning for each.

Add to your frequency list 20MHz and 25MHz which are also being broadcast by WWV (and have been below propagation MUF the past few days).

Set them up in memory channels then scan those memory channels.

What I know
I can scan SPECIFIC band for presence of signal , setting SQL etc...

Can I setup a scan of standard WWV? frequency signals? - 2.5MHz / 5MHz /10MHz /15MHz ?
