[chirp_users] CHIRP and the Yaesu FT-857D

Hi all,

Just wanted to let you know that I successfully loaded a custom CSV in my radio.

Thanks for your help (Marco especially for his great step-by-step
which in my opinion should be added to the FAQ).

I have my CAT cable now working in my virtual Win7 (running on
VirtualBox), so I don't have to use a separate computer when working
with the radio.

I also run Linux Mint on the same host but because HamRadioDeluxe
doesn't run on Linux (I know CHIRP does), I have to use a Windows

Anyway, now I can fully explore the new hobby of ham radio!

Hi Antoon
the correct operation sequence to download from ft857 is:
- switch on the radio while pressing both <- > buttons to push it to
clone mode
- prepare chirp for download selecting menu Radio - download from radio
and setting the com port and radio type then press OK
- start send on the radio pressing C button
download (should) then start immediately and both radio and chirp show
the operation via a progress bar.

For upload the sequence is:
- switch on the radio while pressing both <- > buttons to push it to
clone mode
- prepare chirp for upload selecting menu Radio - Upload to radio and
setting the com port (do not press Ok yet)
- start receive on the radio pressing A button
- press Ok in chirp dialog to start upload

You can find some info on the clone procedure at the end of ft857
manual, chirp simulate the second radio: the receiving one when you
download and the transmitting one when you upload.

I also must destroy the myth that the CAT speed have to be set in any
way: in clone the ft857 the serial communication always take place at
9600 and there's no menu that can influence the protocol in any way.

This question must have been asked a million times already, but as I'm a
new HAM in the Netherlands (since last Monday), I ask it one more time.

I have a Yaesu FT-857D (US model) and a cheap Chinese USB cable that I
bought from Ebay.
I have insalled HamRadioDeluxe and this program can communicate with the
radio over COM3. The cable is recognized as USB-SERIAL CH340 (COM3) in

Now I installed CHIRP and I get the error 'Failed to communicate with
radio: Unable to read block 00 expected 4 got 0'

I searched the internet and found some hints:
- Press the send button on the radio after clicking OK in CHIRP (I
wondered what is 'the send button'? This radio has a million buttons)
- Press the A button under the screen after cliking OK in CHIRP (the A
button has manny functions on the 857, so which menu should be selected)
- Set the CAT speed to 9600bps (did that)

So basically the question is which menu I should select before pressing
the A button. Or a step by step for the FT-857D is also welcome.

Thanks for your help!
Antoon (PA2AR).
