I just got finished building one of these things. It is not quite stock. I
used film caps in the audio chain and the synthesizer loop filter, silver
micas in the RF filters, a Murata CFR series filter in the I.F. strip,
matched hot carrier diodes in the 2nd mixer, and 1N5767 PIN diodes instead
of the stock attenuator diodes.
At 15MHz, MDS is .06uV. No overloading was noted on any band, including 49
Meters. System gain is quite high.
MW performance isn't too hot, but it could be the input filter. I might use
a design of my own and see how it works out.
I had seen this unit in the past, but I didn't want to pay 200 dollars for a
kit..............this radio kit was part of a trade I made a couple of weeks
ago.
Knowing what I know now about this radio, I would say it is worth the kit

Nice. Are you getting the birdies below 7MHz that some people think are
caused by IF from the LED display?

The AGC is reported to be a bit harsh on AM. Have you noticed this, or
is it as bad as the report of eham.com suggests? I wonder if your
tolerance tweaks in the IF stage helped in this regard.

What kind of antenna do you have hooked up to this? I understand
Ten-Tec advises using a long shielded hookup to the antenna. I might be
tempted to replace the phono jack with BNC or coax to make this easier.
Though, I suppose shielded cables meant for audio applications are a
dime-a-dozen.
