Just purchased a IC9700 today at Hamcation. It was great to see one in
person. I got it for $1995. Icom said all back orders should be filled by
end of April. They said they should have enough in stock so that anyone that
wants one at Dayton can get it. I was happy to get it for $1995. No tax or
shipping.

FYI - When I ordered mine from DXEngineering (due to the reservation I
placed), they said if the price drops from the $2098 before it ships, it
will sell for the lower price. That also do not charge one?s credit card
until it ships.

Hello everyone:
Has anyone direct experience using ProSistel PST-RR-55D ring or Creative
Design ERC-51D or ERC-5AD (DC motor if there is one of these available)?
with satellite antennas specifically a WiMo WX-220 2m RHCP cross-polarity
yagi 4.3kG and 4.7m long boom, and also Helix 70cm per G3RUH design 16
Turns, 4.0 kG 2.8m boom length.
These will be on a standard cross-boom of fiberglass tube which is 0.250
inch wall 2 inch OD).
Please share good or bad rotator experiences. My personal requirement is to
build major over-design capability into rotators because my experience (in
the upper midwest) includes ice, snow, winds and I don?t climb so I must
rely on hired help for repairs.
What has been your direct experience with these ProSistel and/or Creative
Design rotors please? Thank you
Very 73,
Dave KJ9I

Bob:
I echo Frank?s good input. I would append this with recommendation to use
a linear (not switching) Astron Power supply because they?re electrically
quiet. If your P/S needs to power the radio only, an Astron RS-35M would
be large enough. On the other hand, if you also need to power other
devices (such as linear power amplifier), then you?ll need to go bigger or
use multiple RS-35Ms, etc. Remember the ratings on these P/Ss are
Intermittent Carrier as used in Amateur Service (ICAS) meaning 50%
(approx.) duty cycle.. Great for CW or SSB. However for any full duty
cycle mode such as WSJT, FM? etc, then you need to derate the power supply
so it?s capabilities are not exceeded.
Switch-mode Power Supplies (switching supplies or 'switchers?) are smaller
and lighter weight with the trade-off that they generate electrical noise
(because of how they regulate the output level) and inherently are noisy.
Linear supplies are bigger and heavier (and less power-efficient) but for
those trades, one gets absolute electrical quiet performance because they
don?t hot-switch power signals away from a zero-crossing. If you wish to
see an animated ?how switching power supplies work? video (approx. 14
minutes), here?s one I share when explaining this concept.

Has anyone experienced problems with the Elevation or Azimuth indicator
(meter) of G-5500 rotator ?? The Elevation meter does not move at all.? The
LVB Tracker shows correct Azimuth and Elevation angles and the G-5500
rotator follows the correct angles.? However, the Elevation meter of G-5500
remains at zero degree.? The Azimuth meter works just fine.? Thanks.

George,
Yes, sadly, I have (and currently do...). In time, I get used to ignoring
the meters ;) Seems like a long time ago I took apart the G-5500 box, and
it was a dirty contact/corrosion/grounding issue of the meters/board? Can't
recall...
If you debug, please share what you find...

I have several RS35Ms and they have been trouble-free.
AFter an ARRL review several years back, I tried an SS-30.? (The Astrons
were significantly quieter than anything else that they tested.)? No RF
noise that I could detect.? That said, I have not put a scope on the DC
lines, but will when I get a chance.
I have bought several more SS-30s and had no noise problem with them.?
So, for Field Day and PA QSO Party, I carry a switcher. (Weight!!)
Good luck & very 73,
