NoBarc's 147.03+ 

UP/development

as of 06/28/2008
This project is currently in progress.

Repeater repairs (06/28/08):

As promised I restarted work on 147.03 after the ARRL VHF Contest. All my bands, 50mhz thru 5ghz worked well this time!

Some of you know we had two problems with the 147.03 repeater in May. The IRLP card I have hung things up a bit. Nothing illegal but not to usable. Also its PA was pulling way to much current for the power out. I had a look at it tonight and it looks like the exciter was in oscillation.  One of the final transistors is blown as a result so I  plan to run the repeater on just the driver stage which puts out 20 watts.  I also do not like the audio into the controller. Always the painful part. I have a deviation meter. As soon as I borrow the calibrated deviation source I will get this all set up and back on the air. For now WITHOUT IRLP.  K1JAW and maybe KB1HZL will be helping me get the repeater back on the air soon. When you hear the VOICE ID the repeater will be up and running but only with 20watts. If it works good for awhile I will need to pull the controller down for the IRLP connection. More on that later.
Work and family are taking up a lot of time this weekend. My 1st granddaughter is 4 years old today. Her biggest wish was to go fishing with grandpa! She caught a fish and had fun!

Signal reports for the 50watt transmitter(04/09/08):

K1JAW/m  Jim Icom Rig, 1/4wave antenna on vehicle reports:
At Kimbal Farms Lenox at traffic light       S7
On Mass Pike at top of first hill East of Exit 2  East Bound  S5
On Mass Pike West bound between hill and and exit ramp for Exit 2 WB  S3 (S3 is barely communication quality)

K2WG Wayne from Canaan, NY at home reports S3 !

WT2Q Bob in Stockbridge, MA reports loud and strong antenna unknown.

WA1ZHM John in Pittsfield near coatsville reports full scale, Ant unknown.

KE3HT/m Tim reports S3 on RT 9 near Dalton VFW with ICOM 706 and 1/4 wave antenna. Not heard at home with HT in Dalton.

PL is supposed to be 162.2 BUT at times it only responds to 77.0? Something is flakey with the temporary controller.
The ARCCOM controller is being refitted for a newer IRLP card.
The PA is dead. A rewire to run just the driver nets us almost 20 watts!

For the most part the radio looks good now. The T/R relay still needs cutting and the radio needs deviation setting but that requires a meter. I also need to make up a  new controller cable.
