I have 2 R2000s and a DX398. Radios not known for their wide
danamic range. I use a ~70' wire antenna, with a 9:1 tranformer,
(with another 1:1 for ground noise isolation) and I have very little
problem with overload. A ham who operates at(or beyond) legal
power lives about 2 miles form me and when he fires up, I do
have to leave the band he is operating on. But I used to own a
R390/URR and a R392/URR and both suffered the same problem.
I borrowed a R5000, and a PCR1000 and the R5000 was
slightly better. The PCR1000 was a POS joke. The DSP was nice,
but I guess I'm a "horse drawn man", and a radio must have knobs.
My Heath GR64 doesn't have any overload issuses, but given it
is a deaf as a post, I am not shocked.

I supect that with a decent antenna, a good matching overload
maybe on over blown issue.
