Jim,
Can you post a link where one can find the "self-fusing Silicone tape like
Rescue Tape" that you describe in post #8 below?

I have a Yaesu G-800 rotator on a roof tower and the motor is fine, but I
hate the controller. I know that the RT-21 by Green Heron is an excellent
product, but @$600 is pricey, and I've never seen a used RT21 go up for
sale.
Can anyone suggest an alternative? I am comfortable building, and am
knowledgeable in electronics. I am also OK with building an interface and
using computer software to control the motor.
I have a G-450A and am perfectly fine with the controller- the paddle
switches are easy to control with my left hand while I am sending CW or
tuning with my right.
Thanks,
73,
Dave WB2PJH

The GH RT-21 is the best option I know of. Check out eHam.net for used units.
That is where I found mine. - John Owens - N7TK

The ARCO controller by MicroHam is very nice. But I suspect out of your
range, considering your thoughts on GH pricing.
Since you're OK with building, you might want to look at the K3NG Arduino
controller to see if it fits your needs:

Dave,
I see them used, for $450 plus shipping. As a matter of fact there was
one on QTH.COM with two Everywhere remotes, last week. Good luck in your
quest.

I have purchased a number of used RT-21's for hundreds off the new price.
They are very frequently listed for sale. In fact there is one for sale
right now as well as an upgraded RT-20 on swap.qth .

I use Scotch Super 88 its 1.5 mil thicker than Scotch 33+ and it has
strong adhesive.? I have used this since I was in the Navvy and will
continue to use it.? It has never failed me.? I also wrap the connectors
with Scotch 2228 Moisture Sealing Electrical Tape too.
I really do not care if it cost a little more I stay with what works for me.

Interesting.? I just watched the video, and? to me the tests were
incomplete - it may be impractical to test some of the most important
characteristics such as the effects of sun and hot/cold cycling over a
period of years.

I like Pete's observation about the importance of environmental
extremes. For about 10 years, W6GJB and I have settled on a first wrap
of a self-fusing Silicone tape like Rescue Tape, with an over-wrap of
Scotch 88. This has proved to be excellent in the moderate climate of
middle latitude coastal California.
What we like about it is that it provides excellent waterproofing, while
still being very easy to remove when needed. We simply unwrap the 88,
then slice the self-fusing tape with a blade.
We've also been using a "Liquid Tape" around places where tape cannot
provide an effective water seal, like the in-line and center-insulator
chokes that Glen has built.

I also use Scotch 88. I do not use that much tape a year to be concerned
with its cost. Scotch 88 also works better in cold weather, in a previous
life I have put up antennas in Chicago in January it worked just fine.
