Re: [IRCA] SDR-IQ

[Nick Hall-Patch <nhp@xxxxxxxx>]

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
