[amsat-bb] PSK31 Satellite Uplink on 10m (final plan?)

[Bob Bruninga <bruninga@xxxxxxxx>]

Here is a new bit of information about the Small
Wonder Labs $89 PSK-31 5W Transceiver Kits.

"The crystal can actually be adjusted over about
 a 10 KHz range, mostly to the high-frequency side.
 The 'stock' PSK10 is configured to display a
 range of about 28.120 (carrier) to 28.1235
 onscreen.

So this solves two problems:

1) A switch could be added to slew the bandwidth up
   from 28.120 suppresed carrier to 28.124

2) This gets it outside of the normal PSK-31 band

3) It takes Peter's suggestion about avoiding the
   CB operators on the 10 KHz raster

4) The transceivers are cheap, readily available
   and usable by Novice Tech+ operators in the US.

5) We can even use one as the satellite receiver
   and save development time..

So the proposal now on the table is to suggest 28.124
to 28.128 as the PSK-31 uplink band for this one
year experimental PSK-31 uplink <==> VHF or UHF FM
downlink satellite transpnoder...  with a possible
launch data of this summer...

Any comments on the current use of the 10 m band
between 28.124 to 28.128 that would be problematic?
