You weren't the only one listening on 80 last night with an HBR -- 
boy, it really was open, wasn't it?  I was listening to the EAs 
working each other in the DX window, about 5-6 GMT.  

These receivers aren't second rate to anything out there except in 
'menus' and suchlike.  Anything anyone else hears, I hear, and I'm 
listening with a 160M fullwave loop with the highest point at about 
20'.  

Okay, so the guys with the Sterba curtains and the five-element 
80M rotatable beams hear things I don't ...

*Next* winter I'm gonna be working people with HBR & HBT.   The 
TX is going slowly due to too much else to do and a lot of time-
consuming mechanical work for the plug-in-coil unit.  

Yes, 160 is practical with the HBR designs.   I did it on the 1MHBR 
and it works just fine.  You put the oscillator above the band, just 
as for 80 meters.  I found I had to pile up the turns to get enough of 
'em.  Unfortunately I can't give specifics because my set uses 
command set coil forms ~3/4" diameter.   

Someone, surely, has the data.
