[TenTec] WIDER FILTER FOR WEAK CW DXING?

Ah, good!  I remember my second rig with a built-in VFO, the Ten Tec 
PM3A (picked up at a swap meet, the fellow thought it was a cute little 
"monitor" receiver without much value, but he did charge $45 that I 
happened to have handy.)

Same deal as Doc discussed.  Wide as a barn.  Listen to both sidebands 
at once!  I had nice high impedance military headphones and could hear 
the whole band, I swear!  I got good at picking out the signal I wanted 
to hear, sometimes by the intermittent beat note from offending QRM.  
Something I would probably not want to put up with today!

I do remember when Ten Tec offered the passive audio CW filter to go in 
line with the headphones (a couple of big inductors inside!)  I didn't 
like the thing and gave it away (wish I had it today, I've seen very 
few in existence, cool little accessory for the PM series.)
