[Icom] AT-150 with other manufacturers rigs

Hi Gary,

That is an excellent interim solution. Here is a table of bandswitching
voltage range vs. band:

Band MHz    Input Voltage
10               0.0 ~ 1.0V
28 or 24      2.0 ~ 3.0V
21 or 18      3.0 ~ 4.0V
14               4.0 ~ 5.0V
7                 5.0 ~ 6.0V
3.5              6.0 ~ 7.0V
1.8              7.0 ~ 8.0V

You should be able to build a logic circuit to decode the band data (if any)
from the Jupiter, and drive a DAC  which in turn generates the Icom
band-selection voltage.

Cheers for now, 73,

I don't have much information on the Jupiter yet.

I did dig out my IC-745 and AT-150 manuals and take some measurements.

My plan is to build a voltage divider network in order to produce the 7
required
signalling voltages and the 8V reference.  I will then run these through a 7
position
single pole rotary switch and 7-pin DIN connector so that I can put the
AT-150 on the right band manually.   I believe the AT-500 already has this
feature,
but the AT-150 does not.

That will be my first cut at this project.  Once I have more information
on the Jupiter, I will try to devise something to do the bandswitching
automagically.
