Re: [Discuss-gnuradio] Cheap portable antenna for SSB + CW w/ USRP1?

[Mark Cetilia]

Thanks Marcus,
I realize I'm asking for the impossible at a certain level—"adequate but not 
stellar" should be fine :)
Glad to know that the roll-off is not so steep as to make >30MHz / <50MHz 
unusable as well…

Btw, I finally managed to get UDP between my external app 
and GnuRadio up & running—thanks again for all the help!

Cheers,
Mark
