Oh I guess Lo-Jac must use 500 kHz ?? I guess no cars with Lo-Jac were stolen in Carroll yesterday evening ...
The relic works even better when I tighten the wire jumper on the back (this solved its apparent instability). This jumper was allow the receiver to also serve as a CW practice oscillator -- Heath thought of everything! The rig has a product detector with LSB and USB settings, an impressive AGC (which is more noticeable on broadcasts than ham radio). And if it is anywhere near spec, its selectiving of 6 kHz at 20 dB is decent (of course I wonder where it hits 40 dB !).
According to what I googled, I likely need to modify how the power transformer is connected and bypassed to reduce noise in the longwave band. I'll study this carefully and of course add a modern 3-conductor cord.
Has anyone ever listened to longwave DX ?
Yes my boat-anchor addiction is under control ... only this one of the 2 items is for myself, and with my HW16 chirping again I choose my battles carefully!
73, curt
