[TenTec] Frequency difference in dual receivers

[Dudley Hurry]

Ken and others,

Having phased locked VFOs is very handy,  but the QST article on the K3 
was a little miss leading, there are other radios with phased locked 
identical receivers,  such as the Flex 5000.   Dual diversity is great 
if you have the distance between antennas.
