[TenTec] Tentec QRP rig--20m

[Simmons, Reid W]

Allan;

I just completed my 1320 a couple of weeks ago.  My tuning range is 
about 72.5 kcs.  I have mine set to tune from 14.002 - 14.0745.  It was 
painstaking work to get the VFO just where I wanted it.  I hit the coil 
with a dab of hot glue here and there, and then carefully squeezed or 
spread the turns (using a plastic stick) until I got the above results.  
I then "drowned" the coil in candle wax.  It has held these settings 
even after final assembly.  Note: after dripping hot wax on the coil the 
frequency will drop about 25 kcs but then slowly move back up as the wax 
cools and hardens.

The VFO coil was fabricated per the instructions and turns were spread 
as evenly around the toroid as was possible.

My 1320 has astounding receiver performance.  I have never heard a 
receiver as quiet as this one.  The background noise is virtually 
nonexistent and the sensitivity is great.  It beats my Omni VI/3 for low 
background noise (but the Omni is slightly more sensitive).  I took it 
on vacation to my in-laws near Pittsburgh.  Using a slightly too-long 
dipole about 15 feet high, I heard and worked stations all over the US 
and Canada, as well as Europe and Japan.  I used a battery pack made up 
of 8-D cells in two Radio Shack D-Cell holders.  I had about 2.5 watts 
output.

Reid, K7YX

Has anyone any suggested mods to up the power out of the 20m TT QRP rig 
(their 1320 kit). Also, is there an obvious way to slightly increase the 
VFO range (to, say 65 or 70 kHz?)
