Re: [UT D-STAR:35] Report on Trip to Farnsworth Peak to work on KF6RAL D-Star repeatersq

Is the 1.2 module data or voice?

All,

I Went up to Farnsworth Peak again on Tuesday with Pat, N6VLU. We have the 448.075 repeater working through the gateway. I actually went up to Farnsworth last Saturday with my Son Brian, KD7BAY and we installed a new Gateway server and get it running. The old Gateway server had a failed power supply and Brian was able to supply a newer and smaller rack mount server. We were able to get it talking through the internet on Monday after a switch was replaced at the KSL end.

I purchased 4 new batteries and replaced them in the APC 1500 UPS that had failed on the old Gateway computer.

We then spent time on the 1.2 GHz DV and DD radios. The programming shows that they are programmed to the correct frequencies but we tried Pat's ID-1 talking to the repeater and the repeater did not activate.
We swapping ethernet cables between the 448.075 and 1.2 GHz radios and the 1.2 GHz radio still does not work. I connected a scope on the rx data output of the 1.2 GHz DV radio and saw no data coming out of it when transmitting from Pat's ID-1.

I also tried looking for data coming out of the DD radio and saw nothing.

Yes, both 1.2 GHz radios were powered up from the RP2C controller.

I suspect that we have dead 1.2 GHZ radios. They are still up in the rack and I probably should have removed them and brought them down.

I also looked at the 2 Mtr 145.125 radio and measured 10 DB of site noise with the 2 Mtr antenna connected and then measured another 10 db of desense when the repeater transmitter is on. This makes this radio almost useless.

This radio is also intermittent in transmitting. Sometimes it works and sometimes it does not.

I looked at the Data coming out of the repeater and it looks somewhat different that what I see from the 448.075 radio.

I removed the 145.125 radio to bring it down that mountain and will probably send it back to ICOM for repair.

I measured the site noise on the 448.075 repeater and it is 10 dB. I cannot measure any desense when the transmitter is on so this is working as good as it can in this configuration.

That's the latest update and thanks again for your offer to help.

There are two radios. One is DD and the other is DV on 1.2 GHz.

All,

I went up to Farnsworth again today, Thursday the 8th of November, and I
removed the two 1.2 GHz radios, the DD and the DV and brought them back
down to the valley since they are not working. I don't see any data
coming out of them on the special RJ45 port when transmitting to them
with an ID-1 mobile. Yes, I know the pin out for the clock and data
output and input.

I will get them shipped back to ICOM for repairs.

Thank You,

John Lloyd, K7JL
