[TenTec] OT: Rob Sherwood's impression of the FLEX 6x00

[GARY HUBER]

Carl, I'm wondering what the FLEX 6x00 IM looks like in a three or more 
transmitter environment.  During my working years I often was confronted 
with A+B+C, A+B-C, ..., etc., TX frequencies mixing in the PAs on site.

A one or two TX site may have no problem, three or more simultaneously 
transmitted signals even on different HF bands, can be a big problem as in 
contest stations, or multiple operators in the same neighborhood.

73 & DX,
Gary - AB9M

I get nothing but unsolicited glowing audio reports on my Flex 6500.
And in the simple test I did comparing transmit noise generated on a
band, it was at least 30 db less than my Omni VII.
