[Premium-Rx] Help choosing HF receiver

[Joseph Pistritto]

i have one of these (Ten Tec RX340) that i acquired from another collector
who passed on.  Ive used it a lot to receive longwave signals and its the
most capable receiver ive personally used for this. (example: the
Differential GPS longwave stations) as well as a lot of shortwave utility
monitoring.
I really like the way the receiver looks in the rack i have it in (there's
also an oak cabinet available which i have too) and its extremely easy to
use.
I have an SE-3 (that i got with the receiver) but i havent actually used it
with the receiver.

So second the motion on the RX-340.  I do see them for sale from time to
time on Ebay.
