Re: Newbie question...How important is 1.2 GHZ coverage?



John,

At first glance this looks fine....but...you looked at the 1296/144 xvtrs.
They do not work down at the 1268-1270 MHz satellite sub-band.  This is why
Steve at DEMI offers kits for both 1296 and 1268 MHz.  BTW 50w is probably
overkill for P3E or Eagle mode-L.  Better to get a better antenna.  At $480
for the 1268/144TL + 2330PA you get 30w to play with on satellite.  If you
must transmit at 25w on 2m then you might look at the DEMI AOS-144
attenuator (25w) to interface for another $80...total still only $560!

I got gobs of DEMI stuff!  I paid for it all, too!  Not a saleman :-)
