RE: Questions about TS-2000

Hello Frank

I've used both the Kenwood and the Yaesu and whilst there are relatively
tiny niggly things and small feature differences about both radios, in my
mind the TS-2000 is the better radio: I still have both, but the I haven't
used the FT-847 for months... I'd say that's the acid test.

I can't explain why people have such strong feelings about the TS-2000. True
there's the annoying AO-27 birdie, but I think to myself 'how often did I
work AO-27 anyway'.

Nope. I don't know why this can't be fixed as it's a firmware bug to my

Yes but the gain's way too high. Consider some attenuation in the 144MHz and
28MHz IFs. I do this all the time to save my down converters. I've lost
downconverters, but never by shooting RF up the wrong end (cross fingers).

If your external TNC has two AF inputs and two AF outputs [1200 + 9600], or
you have two external TNC's, one for 1200 and one for 9600, YES. You run the
1200 through the Mic and speaker connections, and the 9600 thru the ACC2
with menu 50F set to 9600.

Assuming you're using the COM port to do the Doppler correction, I'm not
aware of any software which will also change menu 50F to auto-switch between
1200 and 9600 on the ACC2 port.

The FT-847 has a similar but not identical logistical problem in this

Although it'll run KISS, there's not enough buffer memory on any of the
Kenwood TNC's to do a reliable PACSAT implementation. Of course, as on the
D7 and D700 the single COM port works in only one mode at a time and you
can't get it to work unattended Doppler and TNC KISS simultaneously
[although a very clever program was developed to do this for UI frames on
SUNSAT and UO-22]. But then that's another can of worms and another project
of mine which went on the back burner a while ago.

Other folks will have to comment on this.
