I realize this is a long shot, but...am looking for a PS-4
polarity switch that was used with the 416-TB, 70CM,
antenna. Any information about this switch would really be appreciated. Tks

Luc,
I have a 11 minute recording that starts about 1819utc. I don't have any
software
except Windows sound recorder. As far as I know, it will only make short
recordings.
(one minute) I can edit out the dead air and make a few recordings for you.
If you
know another option, just let me know.

Hi Bruce !
Can't help you with the original PS-4 unfortunately, but ..
I just finished documenting what I did in the past 3 weeks with my 416TB.
See http://www.pa3guo.com (click on ANTENNAS, click on Cuchcraft 416TB).
Henk
"Modification of the Cushcraft 416TB (2x8 elements) 70cm antenna"
(add switchable circular polarization)
Introduction
Cushcraft provided with the 416TB antenna a polarization 'phasing harnesss'
that allows either fixed LHCP or RHCP. For years I used RHCP and was fully
satified with the performance (AO51, VO52, FO29, Cute-II, ...) Click here
for the original Cushcraft 416TB Manual (pdf):
http://www.pa3guo.com/cushcraft_416tb_manual.pdf
Below a picture of the harness as I had it mounted (fixed RHCP) for years:
http://www.pa3guo.com/cushcraft_416tb_original.jpg
With AO51's 435.150 MHz downlink I had an issue as that applies LHCP.
I could clearly notice the signal strength difference between 435.300
(RHCP, strong) and 435.150 (LHCP, hardly audible). Then when AO51 started
to apply repeater modes on 435.150 as well, which I now was starting to
miss out on, I wanted to be able to switch between LHCP and RHCP.
Design
As I had only one relay available (these projects alway start on Sundays
when shops are closed), the option of HOR/VER/LHCP/RHCP was dropped and
only switching between LHCP/RHCP remained.
>From various sources on the internet and an article of Domenico Marini,
I8CVS, ("Switching four Polarizations on a 70cm Crossed Yagi", AMSAT
Journal May/June 2007) I derived the set-up needed for the Cushcraft 416TB,
which has both antennas at 1/4 lambda distance separated from eachother
(A - B in the diagram below):
http://www.pa3guo.com/cushcraft_416tb_pol_system.jpg
The original Cushcraft harness basically consisted of Z1 and Z2 only, and
RCHP vs LHCP was selected by swapping the conductor & shielding at the
feedpoint
of the front dipole.
In the new above set-up, LHCP is obtained when the relay is excited
(signal travels through Y2), else the resulting polarization is RHCP.
Z1 and Z2 form the impedance transformers, which transform the 50 ohm of each
dipol into 100 ohm, which are then connected in parallel resulting in 50 ohm.
Y2 is the phase shifter: if enabled the signal from/to the front dipol is
shifted 180 degrees (1.2 wave).
Implementation
For Z1 and Z2 I used RG59B/U (75 ohm): V=0.66: ((300/435)*0.66)/4= 11.4cm.
X1 and X2 just need to be identical in length, I have used 40 cm Aircell (50
ohm).
u1 and u2 need to be identical in length, u2 is a small piece of copperwire
between the relay pins (~4mm).
Y1 needs to be 1/2 wave longer as u2, I used Aircell (50ohm): V=0.83:
(((300/435)*0.83)/2)+4mm= 29.0cm
U1 is created by soldering the conductors of the two coax cables directly
together and putting a closed copper shielding around that (by soldering the
shieldings/braids of the two coax cables together and around the conductor)
to form again a shielding. Refer to point 'u1' in the picture of the box
below.
Domenico Marini advices in his article to use proper coax relay and in general
describes a more perfect system, including HOR/VER/LHCP/RHCP options. I have
chosen a much cheaper and simpler implementation, which is most likely also
less accurate. So for those that want to built this system as well, I
recomment
them to read the article of Domenico first and decide themselves how to built.
Do not only refer to my implementation described here.
I have used a simple SDS S2-12V relay, which is expected to work up to 450
MHz.
Key is to keep all wires as short as possible. All coax braids (shieldings)
have
to be soldered together via the shortest possible way. See the yellow circle
in the
picture of the box. Parallel to the relay I have mounted an LED, which makes
it
easy to be able to see without a voltage meter (eg outside standing at the
roof)
if the 12V is present in the box or not:
http://www.pa3guo.com/pol_switch.jpg
Again: using a real coax relay would have been much better. Using a waterproof
metal box instead of my plastic one would have been better as well, but I
didn't
have one and it would have made the construction much heavier. But as I am not
aiming for an EME station I decided to give this implementation a try.
First I stripped the antenna and removed the original phasing harness:
http://www.pa3guo.com/cushcraft_416tb_stripped.jpg
The baluns are carefully removed and cleaned as I needed them also in the new
set-up:
http://www.pa3guo.com/cushcraft_416tb_balun.jpg
Next the actual switch was made and placed in a 220V outdoor box (waterproof)
and mounted in the tower:
http://www.pa3guo.com/cushcraft_416tb_switch_a.jpg
http://www.pa3guo.com/cushcraft_416tb_finished.jpg
Results
Just comparing the 435.150 and 435.300 downlinks of AO51 I concluded the
system works:
- In the past I could not hear the 435.150 downlink. Now I can; by selecting
the correct polarization.
- Signal strength of the 435.300 downlink has not decreased compared to the
past (the fixed Cushcraft harness).
Conclusions
With a few pieces of coax, a waterproof housing and a relay a Cushcraft 416TB
can be upgraded from fixed Circular Polarization (CP) to (remote) switchable
Left or Right Hand Circular Polarization (LHCP or RHCP).
Implementation has been done using spare parts as I needed LHCP/RHCP to become
available quickly. However, a next time, instead of a normal relay, I will use
a coax relay as it is expected to give better mechanical stability and
improved
RF performance.

Hello All,
Just a quick hello from the Atlanta Symosium.?? There were great talks
yesterday (Friday) and lot of informal chatting about satellites over the day,
evening, and into the wee hours of the night.? Great fun and interesting
conversation.? The number of fellow hams from "across the various ponds" in
quite impressive!!? Glad to have them in the US.
Today's schedule looks to include many more excellent talks, and of course
there is the annual meeting that takes place a bit after 10 am.??
"Wish you were here."

Good Morning All:
So, after this last week of ISS fun, I have the bug to upgrade into some
simple satellite work. I will be confined to simple FM untill I can
upgrade to all-mode rigs. My question is on coax and preamps.
I will use a pair of vertically polarized yagis to begin with. One for
144MHz and one on 70cm. I have some LMR 400 I got for the ISS project
on 144 but it is so stiff, I didn't use it.
1. If you use LMR 400, do you add flexible sections at the antenna end
and in the shack, using LMR400UF?
Or, should I just use all UF and forget the additional connections? The
cost of the additional connectors (N) both in loss and $$ is probably
advantage $ for UF. Not sure about the loss potential for adding two
sets of interface connections.
2. With a 5-7 element yagi on 144, is it really necessary to use low
loss coax as a opposed to 8x or 8x mini.
Runs here are 35' if munted at 12' and 60' if mounted to roof tower at
about 20'
3. On 70cm, I plan to add a mast preamp, but will use the yagi
"barefoot" to begin with. With a preamp at the antenna, is low loss
coax still required or can the cost increment be put to better use in
the preamp to begin with? The preamp of course also gives a convenient
place for a connector interface from stiff to flexible if desired.
Anyway...I appreciate input from those that have been there and done that.
Thanks

I built a simple "Arrow-style" antenna using the WA5VJB Cheap Yagi
designs. One on 2m, one for 70cm, at right angles to each other, with
an HB9ABX-design diplexer for the two. I use this handheld with my
Kenwood TH-F7E HT and get into AO-51, SO-50 and AO-27 without any real
difficult. Total time for construction about an hour ;-)
If you've got an antenna analyser or even just a good SWR meter, it will
help a lot with getting the 2m part right. I didn't bother tuning the
diplexer much for 70cm because the MFJ-259 antenna analyser I was using
didn't cover UHF - so I just woke up a 70cm repeater on the other side
of town and tuned until I could hear it best.
I find it hard to get into AO-51 when it's busy and people are hammering
it with huge stacked arrays of antennas. When it's in QRP mode I get in
no bother at all, with good reports from all over Europe. Not bad for
an aerial build out of a bit of scrap wood, some brazing rods and a few
feet of hydraulic pipe ;-)

I use RG213/U for the flexible connections around the rotor and in the shack
and have no qualms about this. However, I do not use LMR-400. All of my
feedlines are either 1/2 inch Heliax or 7/8th inch Heliax except for my 40
meter phased verticals which do use RG213/U. That is, all of my antennas from
1.8 MHz to 432 MHz.
Frankly, I obtained a large number of Heliax runs with connectors on both
ends, most of which were 100 feet long (100 feet just makes it from the top of
my main tower - 54 feet above ground - down into my shack) for absolutely
nothing. As such, I would have to actually spend money to get poorer
feedlines.
The losses using RG8/X (or Radio Shack RG8/mini) start adding up above 30 MHz.
Primarily I only use RG8/X for jumpers or for temporary antennas below 30 MHz.
Now RG8/X is definitely better than RG58/U but not as good as RG213/U and LMR-
400 is slightly better than RG213/U. However, 1/2 inch and 7/8th inch Heliax
are better than LMR-400.

loss and $$ is probably advantage $ for UF. Not sure about the loss potential
for adding two sets of interface connections.
2. With a 5-7 element yagi on 144, is it really necessary to use low loss
coax as a opposed to 8x or 8x mini. Runs here are 35' if munted at 12' and 60'
if mounted to roof tower at about 20'
3. On 70cm, I plan to add a mast preamp, but will use the yagi "barefoot" to
begin with. With a preamp at the antenna, is low loss coax still required or
can the cost increment be put to better use in the preamp to begin with? The
preamp of course also gives a convenient place for a connector interface from
stiff to flexible if desired.

Great satellite but underused and hearing Europeans calling CQ NA with little
results. Many regulars not in any order.
G1WPR,G7NFO,G8ATE,OH8MBN,YL2GC,PA1TNO,EA8HB,ON5NY,I8CVS,EA2BVD,DL5RDI,DH5MK,CU
3EQ,EA4CYQ,YV4DYJ I could go on but you get the picture.
So unlock your fixed frequency (FM) and expand your horizon beyond NA. Feel
the excitement from EU to SA and if you are grid square collector, what prizes
await you. And yes you can have intelligent, fruit full QSO without being
smashed. So pull up your blind and see the big picture beyond your
imagination, old timers know what iam talking about. And yes try AO7 the foot
print is bigger yet and that's a big picture.
Just my observation what you are missing. Why get trampled in a small ring and
no where to go.

Hi,
Well yes... but Carlos G0AKI and I did a beginners session at one of the
large UK radio shows instead.
An audience of at least 100 but they may just have been resting their
feet of course. However, we did get quite
a few people come to see us afterwards. The new RSGB education vehicle
is really well fitted out but it was a
shame it was in a large metal clad hall, so no sat demos :-(
Wet and windy autumn day here, Atlanta does sound good :-)
Have a great time!

Greetings,
Does anyone know if there are problems with FO-29's telemetry system? The
structure temperatures seems to be very cold during the daytime portion of the
passes here, even allowing for the long eclipse periods. All four structure
temperatures are about -12 with one structure temperature jumping to +13 on
one pass.
DK3WN's 6 Oct captured telemetry on his web site blog page seems to confirm
these very low temperatures at least on that date.
Anyone have any other information on this?
Thank you.
Jim (N8OQ)
