Hi Robert,

Would you share the how-to back pack configuration you mentioned of your rig?

All the best,

I guess you've never had one apart? Did you see my other post about the zebra strips? These electrically conductive rubber pads are usually used to make electrical contact with an LCD module?

A lot of LCD displays use zebra strips, which are alternating conductive and non-conductive rubbery material. They get their name because the conductive strips are black and the non-conductive ones are lighter. They do not solder to anything. I could not tell if the FT-857 display used zebra strips or not. Thanks for clearing that up.

Re: CQWW VHF

The FT-857D is not that difficult to work on, but there are limited people who offer the service.
There is one shop that does here is a link to his Facebook page.

I have worked on them several times myself, but I don't do it as a business, more entertainment working on radios for local hams.
Most of the parts are available and Yaesu parts are fairly reasonable.
I assume the receiver works OK and that would mean that most of the transmit chain is probably working as well.
Magic smoke leaking out is a sign that the problem could be visually traced to get near the fault and also indicates a higher power area or perhaps enough heat to char the circuit board.
Good luck with the radio.

Hello Zack;

? ? ?I also sent my FT-857 in for repair.? Two main boards and FacePlate need to be replaced.? It cost $850 for everything.? ?The radio performing like new. I have it installed in my Hummer H3. Also added two Grounding Braids 16 ft long attached to Grounding of antenna and works Great with the ATAS-120A Antenna and tunes on all bands. I also live 30 minute drive to Yaesu in Cypress.

Probably not.? That board is all Surface Mount Technology and repairing the board would require a LOT of specialized equipment, assuming someone can determine what the actual problem is with the board.

Quite some time ago, a US ham had bargain priced FT-857's for sale, they were several hundred dollars cheaper than any of the discount stores had them priced at.

What the bargain hunters didn't realize till too late was that they had just purchased the FT-857 designated for sale to Japanese Novice hams, so the rig had restricted frequency range and only 10watts o/p.

Word got around very, very quickly.
