[Elecraft] OT - American hamming in UK

[dave]

I'd be interested in hearing if that unit has RFI problems.  I had one 
that looked identical to that, with the brand "Jetstream" on it, on a 
spectrum analyzer a day or two ago.  Appeared to produce lots of RF 
hash.  Might be OK across a battery, but looked really bad by itself 
(hash at -80 dBm or so).  The hash was riding the power cord as well as 
the output terminals.  Did not do a through check, not enough time, just 
a quick look.

In comparison, my MFJ-4125 produces no detectable hash.  The spectrum 
analyzer has a floor of about -100 dBm so there could be noise below 
that that I'd not see.

Usual disclaimer . . . no interest in either . . . just wanting to know 
what is going on . . . .
