[TenTec] Corsair II knobs ?

[Carlos]

Hi Barry,

You are absolutely right. I have been using the Corsair to monitor
local traffic in 40 meter, where signals are so strong that any
off-frequency parasitic response due to the spurious tones generated
in the DDS seem to be negligible.

What I'll do next weekend is to make proper screen captures of the
spectral distribution of the 5 MHz PTO Vs. the 5 MHz DDS. The stuff I
have at home does not have much dynamic range (probably 75 dB at
best), but I'm sure that the differences are easy to notice.

73,
Carlos VK1EA
