A deal has been struck for PARA to purchase the Sinclair duplexers which we are currently using on the 146.640 repeater. These duplexer cans were recently re-tuned and should be trouble free for at least the next five years or so. The purchase price was $400. We will be paying this out of the PARA club account.
As you will recall, the .64 repeater had been operating with borrowed equipment for some time now. About two weeks ago we replaced the borrowed TX/RX RF deck with PARA owned equipment. This makes the process of finishing out the .64 with PARA owned equipment much easier. The only remaining issue is to replace the borrowed power supply. PARA officals will be watching on eHam for a deal and that too shall be taken care of soon.
The 146.640 repeater FINALLY works the way it was suppose to! Earlier today the PARA antenna crew Dave AA3EJ and Filip AB3HK took down the temporary antenna they put up last week and replaced it with a new Comet GP-3 antenna. All indications are that the repeater is back up to the same coverage area it had before. The only remaining issue is that the audio level is a little low. With a little luck, this situation will be corrected on Sunday.
Thank you to Filip and Dave for putting the time and effort in to get the .64 back up and running. The weather today wasn't too bad temperature wise, but when they put up the temporary antenna last week it was around 20 degrees with a strong wind. They were certainly determined to get this done!
If you haven't given the .64 a try yet, please do so. We're anxious to get some reports so we can see how it is working from the Chester Hill Boro location. The PL is normally turned off, but if it becomes necessary, the correct tone would be 173.8 Hz.
The 146.640 repeater is back on the air.
Filip AB3HK and Dave AA3EJ were at the repeater site today and installed a replacement antenna and feedline. Unfortunately the ladder they had on hand was not quite tall enough to reach the existing antenna, so they decided to mount the replacement antenna below the old antenna. The repeater's coverage will suffer as a result, but this is a temporary situation until the weather is a little more agreeable to antenna work. Can't say that I blame them. Considering that the temperature is 10 degrees outside, I'm just happy they got as much done as they did. Thanks guys, for a job well done.
PARA officials have determined that the recent "deafness" of the .64 repeater are due to a fault in the repeater's duplexers. This is most likely a dirty contact within the cans and would be easy enough to service, but duplexers currently in use are borrowed equipment. It was decided that the best course of action would be to purchase our own duplexers and return the borrowed equipment to its owner. It is believed that replacing the duplexers will return this repeater to normal operating conditions. PARA officials are currently in negotiations to purchase a new set of duplexers. Information will be posted here as this project progresses.
On Friday August 14, 2009 PARA Memebrs Filip AB3HK, Lou WB3AAI and Dave AA3EJ
completed the installation of .64 repeater at its new home in the Chester Hill Boro
building. The repeater is now fully functional from the new site.
After being rained out on Friday July 31st, the PARA antenna crew made another
attempt at installing the new 146.640 repeater antenna at the Chester Hill Boro
building on Saturday August 1st. This time they were successful and the location
is ready to go. Lou WB3AAI even wired into the power panel a circuit breaker and
outlet for the repeater so the power source is solved. The coax is attached and
is ready for the repeater. The contact
person stopped by inspected the site and was VERY MUCH SURPRISED at the
professional job done!
The next step will be to remove the existing .64 repeater from it's present site
in Decatur Township and install it at the Chester Hill Boro building site.
On May 12th the Chester Hill Boro Council approved a request by PARA officials
which will result in the Philipsburg 146.640- repeater being relocated to the
Chester Hill Boro building. Being at nearly the identical elevation as the
existing .64 site, this move is expected to have minimal impact on the repeaterís
coverage area. PARA initiated a search for a new repeater site due to RF
interference at the existing .64 site. Attempts to track down the source of the
interference were unsuccessful and it was decided to find a new location for
PARA will be working with the Chester Hill Boro grounds crew to iron out the
details of installing our antenna and equipment at the site. Details will be
made available as the situation develops.
The Philipsburg Amateur Radio Association returned the Philipsburg 146.640 repeater
to the air earlier today. The repeater is a modified Motorola Micor with a NHRC
controller installed and a set of Sinclair duplexers. All equipment is borrowed
which will allow PARA some time to acquire its own equipemnt.
Filip AB3HK, the PARA Repeater Trustee, has received official
paperwork from the Western Pennsylvania Repeater Council. The transfer of
the 146.640 repeater frequency coordination from Ed K3EDD to the Philipsburg
Amateur Radio Association is now official.
As you may recall, we have made arrangements to borrow a complete repeater to
use on the 146.640 frequency as a temporary measure. As soon as the equipment
is tuned up and ready to go, we will transport it to the repeater site and
On June 7, 2008 Ed K3EDD, the owner of the 146.640 repeater in Philipsburg, and
PARA officials agreed on a plan which will transfer the Philipsburg 146.640
frequency coordination and any remaining usable equipment over to the Philipsburg
Amateur Radio Association.
The 146.640 repeater was originally constructed and placed into service by PARA
on August 25, 1996. The repeater trustee was Dave Posmoga K3MGC, and the
repeater carried the club's previous call sign KB3CLZ. In 2005 a club financial
crisis, and lack of interest from club members at the time, forced PARA officials
to consider alternatives for the continued maintenance and operation of the
repeater. Ultimately it was decided to sell the repeater to Ed K3EDD.
As most area hams are aware, the .64 machine has had its share of problems over
the years. The most prominent problem has been an ongoing noise problem. At times
this rendered the machine virtually useless. For this reason, Ed K3EDD turned
the machine off back in March and it has remained silent.
With the .64 repeater returning to PARA control, the club is now in a position
incorporate the .64 repeater into the PARA network of repeaters. The other PARA
repeaters include the 146.430 (Philipsburg) repeater which will soon be relocated
to a mountain-top tower site and the 444.750 (Philipsburg) repeater which is
expected to be operational by July 30, 2008.
PARA officials have made arrangements to borrow a complete repeater system through
the end of 2008. Our only obligation was to purchase crystals for use in the
borrowed repeater. This arrangement allows PARA to return the .64 machine to
regular amateur use as well as provide the club with some time to consider equipment
options. As soon as the crystals arrive and the borrowed repeater is tuned up,
the .64 will be back on the air. This is expected to occour before July 30, 2008.
