hi, just out of interest, in the us etc do hams have primary use of 70cms, or secondary like us in the uk?
I think one of the limitations in the uk the mod are primary user, and they get rightly upset when people start using
wide bandwidth signals and frequency hopping techniques.
I still wonder why when the foundation licence is such a doddle, that people wanting long range comms don't take this test.
I think that gives access to 10watts. my wife and kids both passed theirs during a half day course at our local radio club.
one of the problems I found with these low power modules is not necessarily the power limit, but the bad selectivity and de-sensing.
in some areas in Lincoln around our cathedral where the local 70cms repeater resides, the radio car keyfobs don't always work reliably.
ive managed to contact the iss, using around 5mW into a 5 section co-linear. I think with these modules though that more selectivity is required.
has anyone on here looked at the signal from these modules on an analyser?
some of the ones I looked at were not very clean signals at all, and most would not have passed any of the spurious emissions tests.
admittedly the ones ive tried were not all that expensive, with two exceptions.
ii would be interested in other peoples results from various modules, this way it may help select various models to suit differing
locations.
