[TenTec] weird thing

[Ron Castro]

If there is a problem in the radio, it would most likely be on the A0 board, 
but would be hard to diagnose.  It could simply be that the radio is at a 
'hot spot' on the beverage transmission line.  A quick test would be to add 
a quarter wavelength of transmission line in series with the RX antenna 
input and see if that has any effect at all on the situation.

A couple of questions:

    Have you looked on a spectrum analyzer or checked otherwise to see what 
frequency all of that power is at when the drive is at 2 Watts?
    What happens when you turn the transmit power off by pressing the PWR 
button or from the menu?
    Do you have the same problem when you use different antennas on the RX 
input, or even no RX antenna, but RX still selected?
    What kind of transmit antenna and how far from the beverage?
