My suggestion is use a classic link coupled balanced antenna tuner. If you
cannot find one to buy the cost of building one for 6m at the 100w power
level should not be very high. The third edition of 'The Radio Amateur's VHF
Manual' (ARRL) contains a couple of examples for use at other

Do you have the sub-receiver installed? If not, the right channel will

The Gamma box is ideal supply for K3 outdoors.
K3 is light and this power supply is incredible light and small.

Wait just a minute. Those old units should be kc and Mc to be correct.
The proper units multiplier designations and their abbreviations are:
kilo = k = 1000
Mega = M = 1,000,000

That is why the capitalization/non-capitalization of M/m is so important.

No way to easily assign the main to both line outputs, and I am not
certain why you would want to do that. Most soundcard applications for
digital modes use only the left channel anyway.
