From my experimentation, I find the an Eton E5/G5 and a Degen 1103 to
be as sensitive on their whips as an R75 is with about 10' of indoor
wire without coax. Hell, they're probably more sensitive.

With coax and a real antenna, the R75 is many times more sensitve.
Even without preamps on.

I purchased one of these sets and my E10 Eton seems just about as sensitive

The sensitivity is not that good at least in comparison on these two sets.
I wanted a new in-box set but the store only had this one, so they said, and
they rest were on back order.
I've e-mailed them offering to return it and purchase a new "In-box unit" as
well as maybe the E1 plus extended warranties on all. �RadioWorld Canada is

I'll let you know the results.

This is very strange �as over many years of playing with radio's the
good tabletops like your R75 are usually at least 10 dB more sensitive
than a portable off the whip.

So I can only assume that you have not got a properly matched 50 Ohm
antenna attached to the R75. I assure you a R75 with only 50 feet of
longwire antenna terminated into a 9:1 matching transformer and RG58
coax runin will give you superb results, far outstripping any portable
on the market.

Also, have you engaged the pre-amps on the R75?
Otherwise the R75 may be malfunctioning, a most unlikely scenario as
they are notoriously reliable = a great radio.

I agree with John on this; try the pre amps on the R-75;

also usng twin PBT �usually helps clarify the signal

-Since the R-75 is Such a sensitive �/ selective beast, it will pick
up and amplify Any household
interference around.

- so, a good, solid co-ax out to a decent ( 30 foot) antenna is
mandatory with this set.

Living in New York, I have the Worlds Worst Antenna �/ Co-ax set up,
but can , with the R-75

Pick up astoundingly faint signals with it

Best,
