[Heathkit] Re: [Boatanchors] SB-10 SSB Adapter

[David Thompson]

In late 1959 My Dad and I bought an SB-10 which we wired.  The unit is far
more than an adapter.  All you need is a VFO or exciter and you have a
complete SSB unit.

The exciter we had was a 6146 90 watts CW exciter with a built in variac so
we could adjust power and cutting this down to about 1 watt and feeding that
into the SB-10 you had a 3 or 4 watt SSB unit.

The VFO must be vert stable and the one we had in the 6146 exciter was one
built by W5DYJ, a master builder.
It was very stable for SSB and CW as well as for AM.

I expect you could build a nice QRP SSB /CW reg with the SB-10, a stable VFO
with at least 60 RMS volts. and a
power supply for the SB-10.  You would have between 1 and 2 watts input
which is far more than you need to drive
a 1KW AB1 amp.

We did add the audio filter as per CQ magazine but I do not recall anything
else.  We had no problem nulling the carrier but the best we could obtain
was 20 DB other sideband suppression.
