Ronen,
I know you are in a different country, so you likely don't have the
same ridiculously outdated rules pertaining to data that we have here
in the US. So I'll spare you the arm chair lawyer stuff.
I had a chance to try some competing cards a few years back. I use
them on an unused amateur television channel in the lower part of the
band. I locked them to 5 MHz wide and transferred live streaming
video just to appease any arm chair lawyers.
I was hoping to use these at modest heights for home to home ham use.
So 50 feet up, etc.
Things I didn't take into account with that scenario; 1 watt at 5 MHz
wide is not the same was 1 watt at a few kHz wide for normal voice.
The using your HT range as a comparison is no good.
I will tell you one thing I didn't really think about with 70cm is the
Fresnel zone is huge. The radius is about 80 feet, where as on 2.4
GHz its about 30 feet. So line of sight is only part of the
equation/problem for most folks. When you only have a watt, all the
path losses tend to be a big deal; be that not true line of site or
Fresnel zone obstructions.
They do work quite far, further than I have achieved with other bands,
if you can get up 100 feet on both ends, etc.
If there was an easy way to do more than 1 watt, I'd expect the would
have been a lot more useable for me at modest heights and or mobile.
I am presently looking into some Friedcom radios for some slower speed
applications (under 192000 bps). I am learning the FC-301 that I have
heard many good things about is now discontinued and replaced by the
FC-302. If anyone has any experience, I'd appreciate hearing about
it.
