Here's an "illegal" one for the shack-lawyers:
My 13 yr old licensed daughter is going on a backpacking trip and will be
carrying an FRS (for comms amongst the scouts). She does not want to lug
along a HAM radio too. (Every ounce hurts after a 3 day weekend of
carrying everything)... I'd like to keep in touch, but I am 40 miles
What if we put an FRS in a box with her 2m rig and left it in the car in
the parking lot (on a central hill) and put them both on VOX and PL.
The scouts would operate on FRS channel X with no PL. Only my daughter
knows the PL of the FRS in the box. Now, I can transmit from home on VHF
with the correct PL for the VHF radio to hear me and the FRS will key up
and she will hear me just like anyone else in her group. But no one will
key up the return link but her, because she only selects the correct PL
when she wants to talk to me.
Legal? No for lots of nit-picking reasons... and we will let all the
lawyers list them... But then conversly, everything is done more or less
within the spirit of the rules:
1) FRS is operated entirely within the spirit of FRS. No mods to the
radio, no mods to antennas, power, or controls. No non-type approved
interfaces to any FRS radio. No attempts to extend the RF range of FRS in
any way. My daughter and I are using it for family communications over
2) Similarly, We are both licenesed HAMS. We are communicating on 2m via
HAM radio. I am the control operator of my station, and my daughter is
the control operator of her's (left in the car.)
3) You could go one step further if you wanted, and say that she is
operating her 2m rig in the car as an auxilliary station under remote
control on a frequency above 225 MHz... ;-)
4) She has taken extra ordinary steps to prevent unlicensed access to her
station. That is she has a control scheme that reduces the chances of
someone controlling her station to less than 0.0018... pretty darn small
way out in the woods..
Don't worry, I'm not going to do this... but it was an interesting
idea... If you ever do expect to provide emergency communications,
sometimes it is worthwhile to think out side of the box in advance so that
if you need to rig up something under stress, you have already thought it
Having lobbed that one over the fence...
Ducking for cover...
