The ARRL Centennial QSO Party is starting very soon (
http://www.arrl.org/centennial-qso-party )
I would encourage everyone who may be interested in activating your
state/territory/district on the satellites to contact the coordinator for
your state (
http://www.arrl.org/files/file/On%20the%20Air/W1AW_2014_sked.pdf )
While I'm sure that some of the coordinators will make an effort to reach
out to the satellite community, others may overlook us when making their
plans. Let's try to get every state and territory activated on the
satellites.
I will be operating on the satellites as W1AW/3 from the District of
Columbia during the week of July 2nd. I look forward to chasing as many of
the W1AW portable operations as possible during 2014!

Purchased a M2 436CP30. Had a failure of the switching block in less than 5
years. White plastic cracked and allowed water to ingress to the switcher.
Customer service?? No return call.

Can that block be treated with a non corrosive lacquer? Sun and weather
does a lot of damage.
Gulf Alpha is no longer producing their OSCAR antennas.

I'm neutral on this topic, but I was curious if the M2 Manual mentioned
anything about maintenance. Here are the instructions:
http://www.m2inc.com/pdf_manuals/436CP30.pdf
There is no mention of maintenance. Of course, it would be a good idea
to check things out regularly. But, depending on where the antenna is
installed, it could be quite difficult to get to it once it's put up. I
can't think
of anyone that actually does yearly maintenance on their antennas. My rule
of thumb is to anticipate what problems could occur and do what's necessary
to avoid them during the initial installation. I always use Coax-Seal and
spray
the heck out of everything with clear Rustoleum.

Well I look my antennas over each year but they have always been
relatively easy to get at even when they were on a glen martin tower on
the roof, I could see every other year if it is a major undertaking but
based on his call he is in New York, to think you can put a antenna up
and ignore it for years in a area with snow and freezing temps stretches
reason.
I'm also a fan of coax seal and some sort of coating on the
elements, When I look my antennas over I'm checking for loose bolts and
UV damage to plastic parts and coax, out on the west coast it is the Sun
and heat that is the thing to worry about.

I am not a fan of COAX Seal, it tends to migrate into the connector.
In the Hampton Roads area, a NAVY town, we use the old NAVY way:
* Light application of high great Silicon
* Double sided electrical tape rap
* Electrical tape rap
* Spray lacquer over
* Nylon tie on each end
Great seal!

I am breaking with my normal practise of not posting to the amsat-bb:
I have a M2 436CP42 which is even larger than the 436CP30. I have
had it since about 1999 as it was used for AO-40 uplink. I wired
mine in RHCP without the optional polarity switching relay so I have
no direct experience with the relay. My antenna has performed just
fine in the 14-years it has been mounted outside so the antenna is
certainly of good construction. I made no extra protection other
than good sealing of coax lines.
The relay in question is probably not manufactured by M2 so quality
may not be up to their usual standard? The white plastic obviously
was not UV resistant. Instead of bemoaning this just replace it with
a good coaxial relay like the CX140 from Tohtsu (or suitable
substitute) which you can buy from DEMI, RF Parts and probably many
ham dealers.
I wonder if M2 even stocks these relays anymore? No comment on their
customer service. You should have heard back from them.
I have several M2 antennas in use: four 2mXP-20 for eme, 436CP42 AND
2m7 for satellite, 420-450-11 for general purpose UHF, and several
splitters and other components all which perform well for over a
decade in Alaska's wx.

I am prepared to consider that this is an anomaly. Have a look here:
http://www.flickr.com/photos/n3ykf/11312549334/
and feel free to browse the three pictures of the antenna.
Told the people at M squared and got nowhere. This is definitely an
engineering problem.
The issue with the front driven element is that it, too is cracking and it
too will fail. Probably sooner than later.
