Hello All, ? So far, my 857 keeps on tick’n, however, we used to utilize some old industrial power monitors that developed stripes on the lcd displays and found that if the Zebra strips were just replaced, the displays would work without the stripes.? Zebra strips are used in place of wire conductors between the glass Indium conductors of the actual LED display and the PCB that drives it.? ? Fluke meters a while back also had the same problem.? I’ve had to get them replaced on my 87 from time to time.? Age tends to shrink the Zebra strips so the contact will become intermittent. ? This link is the first page that showed up on Google.? I don’t represent the company or its products in anyway. ? Zebra strips: ? ? Your mileage may vary though. ? --jeff Wb7aht

Re: CAT update blocked during TX
And, if I'm not mistaken, you're supposed to keep transmissions very short when working satellites.

This is what it looks like inside the FT-857 Display Panel
|
Zack,
The short answer is, NO, there's no EASY way to solve this problem, except replacement of the assembly.
Here's the longer answer, and the reason why.
The failure is a poor or decaying soldered connection between the display screen and its mating circuit board, inside the control panel. To the best of my knowledge, no actual parts have failed, so replacement of components shouldn't be necessary.
HOWEVER, re-soldering the pads requires a fairly complex set of soldering skills, and likely, specialized equipment. Not a trivial job, certainly not quick and easy.
Do some searching, and you'll find lots of other threads about this around the Web, and huge amounts of mis-information and superstition-based answers.
Good luck sorting it all out!

I am sure this has been asked before, but is there a fairly easy way to get rid of a few vertical stripes on the FT957 display? The seem to come and go.

Hy. I Had the Same,...
After master reset. Everything was fine...
Check ist Out..
Good luck

Re: CAT update blocked during TX
Peter: This behavior for several Yaesu radios (857, 817, 897) is mentioned in the SatPC32 documentation.? (Hints->Yaesu, see the Reame(Yaesu).txt file).? Manual tuning (front panel) works, but CAT-controlled Doppler correction disabled when PTT pressed. Recommendation is to keep transmissions short, especially when Doppler shift changing rapidly.

Re: CAT update blocked during TX
Yes that is a limitation of the 857 when using for satellite operation.? It really isn't a big problem if you keep your transmissions short.

Re: CAT update blocked during TX
Hello Yono,
I tried it here, and indeed, the 857 will not accept frequency change commands by CAT during transmit. I am pretty sure the CAT interface itself functions, as I use CAT command to switch between transmit and receive. So I guess it is designed this way.

CAT update blocked during TX
Dear all,
While qso with a friend that uses a FT-857 thru a linear satellite, I noticed he always drifts upwards. He said GQRX was not updating the freq while TX and he has to release the PTT button between syllables so the radio catches up.
Is this a known bug (CAT port is disabled during TX), or the CT-62 cable got RF interference during TX.
Let me know your thoughts,

Re: Quickly change power levels
Thank you everyone. I learned a few things. I'll pass the info on to my Dad.

<Announcement> 2M 440MHz added to the 100W 10-80M loop
There is now a 2M & 440MHz loop integrated into the model 100W 10-80M MagLoop. A most excellent choice for the 857 that also supports VHF UHF & HF.?

Re: Quickly change power levels
You should be able to program one of the screen menu buttons (Menu 065 - 067) or the mic buttons (068 - 070) as RF power set (Menu 075).? It would make it easy to quickly bring up that setting.

144 MHz: 20W
430 MHz: 10W

Re: Another newbie question - programming frequencies
Eric,
I must be losing my mind.... I've got this thread being started by VK2DHV (who according to the ACMA database is David).
All good - Stay safe.

Hi Cameron,

Stuart is the person who originally asked the question! Simple ACMA lookup.

Eric, Zak et al (although I'm not sure who Stuart is)...

This legal situation is actually much more onerous than it appears on the surface - hence why my response included specific reference to the Act (an Australian legislative document found ) and the applicable clauses.? Even being in possession, especially if the rig was made capable of transmission on those frequencies (even if only programmed as 'receive only') would like be deemed as 'with intent to operate'. If the radio was found to be functional (and especially given that the question has been asked in a pseudo-public forum) then there would be little in the way of a 'defence' (I can think of one but I'm not placing it into the public domain).? This is a specific issue I have asked our National Representative Body to have addressed in future revisions of the legislative instruments.

Re: [FT-857] Another newbie question - programming frequencies
Hi Zack,
?
Agreed, however, Stewart was also mentioning about transmitting using the radio hence Compton’s, and my, comments about its none type approval here in Australia. One of the requirements for type approval here for non amateur band equipment is that it not be programmable, on transmit, from the front panel.
?
73….Eric VK2VE.
?
?
Yes, but if he wants to listen to various frequencies? without having to tune to them each time, the rig will accept any frequency in its range for receive only. I am never going to transmit on LF NDB frequencies or AM BCB frequencies, but I have quite a few of those programmed into the radio with CHIRP.
?
Although technically possible your amateur rig, FT 857, will never be permitted to Tx on those commercial frequencies, sorry, you will need a commercially approved radio.
