Fw: [McHUG] Lite+Xtall Beta kit

[Peter Morton]

Hmmm.  I replied to your McHUG email and it went to your home email, not to 
the reflector.

Anyway, I just got confirmation from Tony that my lite-xtall will be shipped 
next week.

Thanks again, Rich.  It looks like an interesting project.  I'm looking 
forward to trying it out.

>> The upgraded SoftRock Lite includes 0.975 inch by 0.525 inch plug-on

>> the desired band. Receiver sensitivity should be equal to the recent
>> performance numbers posted for the RXTXv6.2 RX function.
