Author Topic: Grounding a FT-857??  (Read 1633 times)

I`m probably going to feel stupid after asking this question.

I recently obtained a Yaesu FT-857 as part of an estate purchase, and I`m in the process of setting it up for testing, prior to listing it for sale....When it came to grounding it, I couldn`t find any normal way to attach it to the ground system.....The manual refers to a "rear panel ground lug"....There isn`t one...In fact, the only screw back there are the miniature ones that attach the SO-239`s....

Is there an FT-857 owner out there that can solve this mystery for me?

Grounding of equipment is a controversial subject - many hams choose not do, other hams wouldn't dare go without....  but if you are planning to ground the 857, you can attach the ground to one of the 4 mobile bracket screws.  Just slip the braid (or ring terminal, or whatever) under the mobile bracket screw before you tighten it.

Hi Dan...Yes, I know..That`s why I said I could`t find the "normal" way.

I`m puzzled by the manual saying to use the ground lug on the back panel when there isn`t one on the back panel.

Hopefully a FT-101 owner will chime in and solve the mystery. I`d like to be able to alert the new owner before he buys it.

Thanks

I just checked my FT857D and also no ground screw.  not even a place for one.  I think yaesu just likes to mess with us, haha.

An easy fix.  Remove aerial from radio.  Slip a jubilee clip over the PL259 plug and refit the aerial. Put the earth wire between the clip and the plug then tighten the screw.  Good tight fit will result.

Here's what I did and it's easy.  I bought a cheap "Coaxial Spark gap" arrester.  I screwed it in the back and used the grounding screw on it to go to ground.

Plug it into a dummy load to test output, use a signal generator to test input. Far more valid than hooking it up to an antenna and making a contact.

Pretty much a waste of time since it will still be a Yaesu & have that pathetic excuse for DSP filtering & a poor at best receiver.had one & it's hands down the worst Amateur Transceiver I have ever owned or operated.I have said many times that I would not have another one even for FREE if I was required too actually keep & use it because i found it made Amateur Radio Very Very much NOT FUN.

I hear ya, they're nothing special.

The receiver is better than the one in the FT-817, but the FT-817 is actually quite a useful radio!
