We started out with a nice Soney portable short wave receiver only, and with a modem
connected to the laptop
, it was able to download Weather
Fax as well.
You may get better reception
by connecting the wire to a chainplate or mast
bolt. Since it can't transmit, it can do no harm. It also "might" be better (IF it's a portable with LONG telescoping antennae), to receive in the cockpit
, & swivel it for best reception. Experiment
22 years ago, I have used an "either / or" switch to share the VHF
with a FM radio
, and it had some form of protection for the VHF, should the mike get keyed with the switch in the wrong position.
WARNING... You will blow out the VHF to key the mike with no antennae attached!
Also... a simple splitter will not work. When using the VHF, it would send it's transmission
into the antennae AND the short wave radio
, which is bad for both.
I would therefore avoid the VHF option as too risky.
with the rig option, it can't hurt...
