[TenTec] Argosy I issues as well as Argosy II issues

[Ed - K9EW]

Hi Mike,

Maybe the heterodyne oscillator for 80m has low output, or it may be
far enough off frequency to be attenuated by the 80m filtering.  If
possible, follow the RF from the PTO through the mixer with an
oscilliscope on a good band and on 80m and compare voltage levels.

Good luck - hope you find your missing drive level.
