Re: Low power output on SSB and CW
#857D
I don't thank that there is a ceramic filter in the CW and SSB path. There is a crystal filter, but also there is an if AMP in there. I don't have the schematic nearby right now, but look at the path from the SSB filter to the down stream amp to the left.

Re: Low power output on SSB and CW
#857D
Hi Alex.? ? ALWAYS expect that the 455Khz TOKO Ceramic Filters are a problem.? Always. If they have never been changed, change them. ? And be very careful changing them.? They are not easy to get off.? The ground plane on the 857 and 897 Main Units are a wicked Heatsink.? You need good tools to do it. Not to mention all the very small components around them on the bottom side of the PCB. ? Then test again.? It will most certainly have an effect and likely fix your issue. ? Ronnie VE3NLS

E-mail ? ? ? ??ron@... Mobile?? ??705-791-6634 ? ? ? ? ? ? I wonder if I get the ceramic filter problem on my FT-857D.? TX power on FM looks good, I can see it draws 12-15 amps on the power supply. But on CW and SSB, it does not draw more than 4 amps, and the ALC does not kick in. Any suggestions? Thank you.

Can the FT-847 DSP Board be used on FT-857?
Question: Can the FT-847 DSP Board be used on FT-857?

If yes...how?

Thanks for helping.

Just to close this one out, I had success with another cable.

I can read and look at individual photos much faster than watch a video on Youtube. I'd rather have info in printed form. And Youtube has an awful loot of false info on it.

Zack,

de KM6WWY ? Can you give more info on how you got CHIRP to run on a Raspberry Pi? I have a Pi 4 that I have been putting ham radio applications on.
Zack W9SZ
I have usually found that Com ports and baud rate is what trips up Chirp, and most programming/communication software when using Windows. There is also an R-pi build that I have used with no problems on a pi-4. Selection of the correct radio type is also important.?
You should be able to watch Device Manager ports list when plugging in a programming cable. An alert and a new com port number should pop up. If not, your programming cable chip drivers may not be installed or there is a driver problem. Not all programming cables are created equal either.?
de KM6WWY ? Interesting. I have been using Windows 7 with CHIRP for my rigs. It works fine.

What computer are you using. Windows 10 on some computers will not work with Chirp. There is a driver issue that was fixed in Windows 11. Don Dodge Cell 714-271-7888 W6SNX On Nov 5, 2024, at 7:36?AM, michael.john.slattery via <michael.john.slattery=[email protected]> wrote:

Yes, in both computers I do see the Com port correctly.? Testing various baud rates and settings has not yielded better results.

One thing I ran into was that there were a couple options for the FT-857 I have. I forget what they were, maybe Japanese, European and US. But I had picked the wrong one. I do know my radio is not Japanese but maybe it wanted to use the European version for the software? Anyway, once I had the correct one selected, it worked.

I have a JA FT-857M (50W) and a US FT-857D (100W).
The hidden service menu can be turned on with the US-857 only, not with the JA-857 so I cannot change the RF output of JA-857.
And both US-857 and JA-857 jumpers on the main circuit boards look the same but what happens when modding them are different.
I suppose the meaning of each jumper will vary by the embedded CPU programs or the regions and the models of the main circuit board, but I'm not sure.

I'm asking OY1R which jumper setting he used to get that exact result he reported.

If you have a Japanese version of the 857, there is noting you can do to get that to the US bandplan and the full 100 watt output.
