I recently bought an Icom IC-R3 (hand held communications receiver) and a
Yaesu VX-7R handy-talky (can tune .5 to 1000 Mhz). Both of these devices
can't pick up a single shortwave signal. And this is on a long wire antenna,
not the rubber duckies. (They both receive great on VHF/UHF. The IC-R3 even
manages to pick up fringe TV channels.) The same antenna connected to my old
Kenwood 599 receiver brings in plenty of HF signals, both shortwave
broadcast and amateur.

All handheld "DC to daylight" recievers are useless for decent shortwave
reception.
If you expected them to do so, get rid of them or bring them back to the shop.

Hello MRe,

Off course a good HF receiver cannot be compared with the HF section
of a "DC to daylight" receiver, but when you use them with a nice
preselector/attenuator combination, they can work reasonable. I forgot
to mention the MVT7100. That one also works reasonable with my home-
built preselector. I have 3 taps on each coil, so I can change the
bandwidth of the preselector.

Handheld recievers are meant to be used HANDHELD. They are not meant to be used with
all kind of boxes like preselectors and filters and the like.
What is the use of a handheld (shortwave) radio which can only be used with external
boxes on shortwave? Better buy a decent one.

Another reason for using the wide band receiver is the search
function. My R5000 is not designed for scanning/searching.

Scanning/searching on lw/mw/sw is not my kind of thing. You will miss a lot.
Scanning with the before mentioned preselector is useless because most preselectors
don't track with the reciever.

Greetings
MRe


If you are planning to do LW listening, the performance of the AOR8200
is worse (as the manual suggested). The nice thing of the AOR8200
with respect to the MVT7100 is the 3 bandwidths you can select in the
AOR8200.

If you want to listen to SSB with a wide band portable receiver, the
BW of the filter is far to high (there is mostly no separate BPF for
SSB installed [the AM filter is used]).
