The RFSpace radios don't seem to like high impedance antennas
directly connected to the antenna terminal Phil. If you have a
Beverage matching transformer handy (for those DXpeditions?) you
could try using that to get something closer to the 50 ohms the
SDR-IQ is looking for. Of course, if your house is anything like
ours, you will get local electrical noise at greater strength using
that method. An antenna outdoors might be preferable, but I
suspect the matching transformer is a must no matter what you do if
you want to use a random wire.
Do you have an old commercial ferrite loop or a Sanserino loop
kicking around? They tend to have low impedance outputs also.
best wishes,
Nick

I have recently acquired a SDR-IQ digital wonder radio.
Right now, I'm in the "playing with" stage... seems to need a bigger
antenna than 30' strung around the house.
Any ideas/tips on operation or antenna welcome.
