The R-10 has all the sensitivity and frequency agility
you'll need, but it lacks the selectivity required for
SW broadcast.  It's AM filter is 15KHz wide.
The SSB filter is 4KHz wide.  There's no synchronous
detector either.

I am thinking of getting into shortwave, I have a R-10 on
lay-away at a local store, I know it covers the shortwave
Freq's but does it do a good job?

I also do not have a way to put up a dipole, how well will
a end-fed longwire (approx. 50') work for general shortwave
coverage?

thanks for any input.

The R10 is a good SW receiver for a handheld unit. It
represents a good mix between sensitivity and strong
signal overload protection.

50' will work well but you'll run a larger risk of overloading
the R10. If you stay with 50', I would also have another
antenna handy that is half this length or shorter.

Good luck!

It has to be better than the R-1, probably adequate for strong signals.
But no DC-daylight receiver can be as effective as a SW-only tabletop
receiver such as the Drake. The usual shortcoming in such receivers is in
the adequacy and choices of bandwidth filters.

R-10 with an external antenna is more than sensitive enough for shortwave
reception. However the AM filter is 15 khz wide.  Not nearly selective enough
to pull intelligence out of a crowded band.  On the upper bands however, it is
a very nice radio.

As much as I respect Rich's reviews of scanners and his information-packed
webpage, I must disagree with him on this.

I purchased an R-10 and tried it out -- it seemed to be off a little in its
tuning, so I went to SSB mode and tried to zero-beat WWV.  The tuning was
off by 1.3kHz and wandered all over the place, i.e. the hetrodyne wandered
up and down frequency quite a bit.

At the store where I bought it their demo model did exactly the same thing,
so I got my money back.

I wasn't expecting W-J-level perofrmance out of it, but an AR-8000 does
far, far better.

Hi Eric,
   Sorry to hear you weren't pleased with your R10. Perhaps you got
ahold of a particularly bad "batch"? Did you happen to compare the
serial #s on your model and the demo you tried out? Did you happen
to notice any settling after the unit was allowed to "warm up"?
   I have heard few complaints about the R10...granted, not everyone
can agree on a radio due to vast personal differences...but the R10
is quite popular and does a decent job on SW. I have not heard of
any drift problems on the R10, but then again maybe the rest of us
aren't quite as demanding or the SW afficianado you appear to be! ;-)
   While I did recommend the R10 as a decent SW radio, I probably
should have ranked it amongst the other contenders. You are correct
that the AR8000 does better. In my tests, the R10 typically comes
in third in my overall HF testing behind the AR8000 and MVT-9000.
It does do much better than the X10 and WS1000/2000 though.
