It's in the manual, page 41. It represents a key in a keyhole and it means you have some level of panel locking enabled. Read the last sentence. 73, Kent K9ZTV

I have a small symbol in the bottom riight hand corner of my display.? It looks like a tiny box with an F on top of it.? Does anyone know what this is?? I thought perhaps it was the running man but

Oh, yes, I did. I forgot to mention that. It didn't change anything regarding the performance. Zack W9SZ

Hi Zack, As you have said that you lost both 6m and 2m, which come out of different PAs (Q3022 & Q 3023 for HF/6 and Q3024 for 2/70cm) the only thing common to both of those is the 13.8V supply to

Hello, I don't think Yaesu is repairing the 857D any longer. WD8BWW has been mentioned here as "the man" for display replacements. I visited him near Kansas City when he replaced my display. It turns

I recently had a similar issue with another non-857 radio. Everything looked OK voltage wise, but no power out. I put together a simple RF probe and was able to follow the signal to where it quit,

This might be a stupid idea but have you tried the factory reset?

Well, I'm completely stymied by it now. I make a living repairing electronic equipment, some of it rather exotic and with no service manuals or schematics. But I can't figure out what's wrong with

That's reassuring. I can't find anything wrong with that part of the circuit. And I did have the Tuner/ATAS (menu item 85) set to OFF. I want to check the HF TX, V/U TX, VTX, UTX and 50M AMP lines

Hi Zack, I believe that the circuit is actually protected against shorts as Q3013 and R3045 work as a current limit to prevent it putting too much current into the antenna. I think that Q3008 and

That could be. I did come to realize something. My 6 meter Yagi has a hairpin match across the input - and the coax. At DC, that would look like a short to whatever the coax is connected to. If the

Hi Zack, Looks to me like it’s the circuit which supplies the two voltages to the HF antenna socket to drive the ATAS antenna up and down. The line labelled ANT ends up at the antenna connection on

I have been looking at the service manual for the FT-857D and I may see a potential problem. I am not at home now, so I can't check things out. But on page 8 of the service manual, under the PA Unit

I have all homemade beans. They have been optimized with Yagi Optimizer. I built them so they can be transported in a car disassembled and then rapidly assembled on site. I have been using them for

Man, that's really a bummer.? When the magic smoke comes out it never feels (or smells) good.? Please share the failure with pictures when you get it figured out. Were you using some homemade beams

I went to my favorite hilltop in EN50rl for CQWW VHF, managed to get the 6 and 2 meter Yagi antennas set up in the hot sun (the 6 meter Yagi is BIG), hooked everything up and it seemed to be doing

Thanks for the reply I found the instructions and yes it is a Chinese knock off... as of now it works fine with swr setting but will calibrate it later..73 Russ ???Russ Ouellette rjo601@...
