Howdy all.
Well, Clay (KF8UI), Dale (KC8ZXF) and myself went up to the repeater site tonight. We took the repeater offline and did several tests. We found that our PL board, when we used the high and low pass filters, caused the pulsing noise when transmitting. Once we removed those filters, the audio was nice and clear.
We also got the voter back online. It turns out the voter was looking for an audio ground on a different pin than what we were providing the ground on, so the circuit wasn't complete, and no audio was passed. Once we changed the ground to the proper pin on the DB9 cable, audio passed from the repeater to the voter successfully. We did test moving the receiver audio from the amplified circuit to the discriminator, but when we did, the audio level was significantly lower than the remotes. When we switched it back to the amplified audio, the levels were almost exactly the same.
We also reset the antenna to what it was prior to Sunday. We attempted to adjust where the antenna null pointed but it caused issues with people connecting. We're having Clay's boss, Ed (N8OVL), run a computer based model to show us how we can optimize our antenna to it's maximum output. Once that gets run, we will then try and make more adjustments to the antenna.
So, all that's left is to get the antenna model so we can update the configuration and we have to get the cans re-tuned then we can close out the 26 update project and move on to the 100.
Things are definately moving along.
If you get a chance, leave a comment when you get to test the 26. Let me know what your using to connect to the 26 with (HT, base, mobile), what PL your using, your power level and your location your transmitting from. I'm just trying to get an idea of the footprint of the new repeater.
