[TenTec] Fix Omni-V

[jacrux <jacrux@googlemail.com>]

Note also that band switching is done with reed relays. Check that the 40m 
band pass filter board ones are not stuck, or the coils open circuit.  
(I am just replacing K1 and K2, because of an intermittent return to Receive. 
Sometimes I get signals; sometimes only weak signals, and sending a dot often 
fixes it --- until next time.)
