just out of blind curiosity, is a rs handheld freq. counter worth
having? have op to get one cheap. I have a heathkit im2410 in mint
condition but it only goes to 225MHz.
tnx

I've had one since they first came out.  It works well and is priced
right.  Mine seems to be pretty much dead accurate.  If its frequency
snooping you need then there are much better units but for the bench it
works well...73

They're dead accurate to about 500Mhz.  I've tried it at both 800Mhz and
900Mhz, and at times the RS counter has been off as much 5Khz.

The initial calibration of the Radio Shack counters seems quite accurate.
I've checked two of them against a GPS-based timing reference, and both
seemed to be within about 1 PPM.  They don't drift much either, since
they run quite cool.  They seem to be more accurate and stable than
a couple of bench frequency counters costing several times as much as
the RS ones.

Of course, the RS counters are good for RF only, while the bench counters
cover a much wider frequency range.  And the maximum resolution of the
RS counter is 100 Hz for the least significant digit, so you can't even
measure frequencies under 100 MHz to 1 PPM resolution.  For checking VHF
and UHF transmitter or VCO frequencies, it's great.

I'll use it for everything from freq. snooping to bench testing/freq.
aquisition of radios I aquire. Any freq. snooping I do will be blantant
as I will probably have access to the transmitters up close as far as
police, fire, ems goes. I'm a Medic in a small town, so everyone knows
everyone but not all the freq.s  My handheld radio does my pl snooping
and all so just need something to confirm hf  to uhf operation of unk.
freqs and probably nothing higher.
Thanks all!

alrighty, due to the overwhelming responses with a 'thumbs up' I have
decided to buy!! Now how much can I get for a MINT (needs a led number
block on the fourth kHZ) heath IM-2410? Pristine condition.. Looks like
it was build 4 hours ago. really.
tnx,
