Re: [IRCA] Radio switching network

["John H. Bryant" <bjohnorcas@xxxxxxxxxxxxxx>]

Rob,

Thanks for the tip on the MFJ unit... I wasn.t aware of it.  It does 
do the same thing, but the e-ham reviews question the reliability of 
some fairly cheap switches.  For those who are really short of radio 
time or who shy away from even simple construction, the MFJ unit 
might be the way to go.

I do have a bit of ground loop problem about one time in 100 or less 
with this unit, though I only notice it when I have one receiver on, 
the other off and both connected to the switch.  Its never been a 
problem for me while DXing.
