Ron,
The TT311 is still available. It was about $96 when I got
mine about a month ago. It is a box with circuits and gates in it that
convert 10 bands into 7 frequency ranges. Several bands
are combined so the outputs are 160, 80, 60, 40/30, 20, 17/15, and 12/10.
The TT 236 cable is no longer made. Further it only has 6 frequency ranges
because 60 meters wasn't available at the time.
I got a cable from
Riley Accessories (Larry R Riley)
7507 Ledgewood Drive
Fenton, MI 48430 - 9225
810 740 1217
http://rileysaccessories.tripod.com/
that has an extra conductor for 60. This will be especially useful if
that band is expanded. The web site says the cable plus shipping is now
$54.
The TT253 remembers a set of 1 frequency for each of the 7 frequency
ranges for each
of the 4 antenna positions. If you are using open wire feeder as I do,
you may want
to follow Rick Williams' (VE7TK) suggestion:
"The OTHER option is to purchase a good external balun and bring your
doublet
to the balun then feed the coax from the balun to a 4 position coax switch.
Then take 4 coaxes to the 253 4 inputs. Then the 253 will treat these as 4
different antennas. And you can set-up the 4 253 ANT switches for 4
different combinations of frequencies on your doublet."
This could give you 28 total CW and SSB settings by adjusting the
antenna switch on your tuner and the coax switch.
73,
Ed, N5EI
