I just purchased a used ft-857d. According to the store owner, and the manual, it should have DSP and 60m. Neither seem to function, though the radio seems to work fine otherwise. I was told the radio is just under 2 years old. Ser#6D590081. Does anyone know where I can look to see if this rig should have these features, or if it is "baked"

tnx, rob

There's an 'Unofficial Wiki' on the FT-897 as well as a yahoo groups.

First two positions 6 D indicate year and month of
manufacture - 2006 and April.

If it's a 'D', it'll have both the audio DSP and
60 meters.

Actually, I think the "D" adds the TXCO - highly stable
VCO.

Should be a 'DSP' button in the upper right corner.
Pressing it should bring up 3 menu items - DNR, DNF, and DBF - Noise Reduction, Notch, and Band Filter.

For 60 meters, there should be a set of memories pre-programmed in the 'M1' bank - M1-01 thru M1-05.
These would be the preset 60m channels.

I've yet to use 60m, but the audio DSP is very, very
useful. I've found it to be a fun radio to use once you get familiar with the menus.

This morning I pulled the covers off, and sure enough, no DSP unit! No wonder it does not work! The 60mtr option is not important, but given the date code, I thought it should have had both.

tnx, rob, ve7rwn.

Whooops. This is what I get for posting late - very
late.

I missed one digit - you said 'FT-857'... and
I 'assumed' (and we all know what that makes us)
FT-897.

For the FT-857D, the DSP is OPTIONAL (according to
the info on http://www.yaesu.com/).

60m is INCLUDED.

The TXCO-9 (temperature compensated crystal oscillator) is an option too.

Sorry - I'll have to read more closely when posting
at 2:00 AM.

Good radio, though, and about as small and portable
as they get.
