The repeater antenna has been repositioned and braced against excessive sway, and all repeater operations are back to normal. If you recall, high winds had blown the antenna into the tower and one of the elements had hung on the tower structure.
Six meters FT4 and FT8 were busy this afternoon. Seems like Cycle 25 is heating up
I picked up a new “Pocket Portable” iambic key from CWMORSE this week. It’s 3D printed and is really nice quality. I’m looking forward to getting out into the field with it soon.
Field day is coming up soon. Our club, in concert with several others, is mounting a combined operation, as we have in past years. Hopefully, it’ll be a great event.
A further update on the repeater antenna … The wind whipped it into the tower, a U-bolt got latched under one of the diagonal tower braces, and it’s stuck there. We’ve switched over to the backup antenna (just a few feet below this one), and will tend to the stuck antenna during the next tower inspection, unless Mother Nature pops it loose before then.
Our plans are to add a pvc standoff to hold the mast away from the tower. The backup antenna (a dual band fiberglass stick) already has one. Hey, hindsight is 20/20, right?
Somehow, out main repeater antenna has flexed a bit too much! From the picture, it looks like the top may have flexed into the tower structure and gotten caught. We’ll be going to the site on Saturday morning to further evaluate the problem. I haven’t seen the actual antenna yet … just this photo that was sent to me. We’ve still got the backup antenna if needed.
As of yesterday afternoon, the W4MT UHF & VHF FM repeaters were back on the air. We got the repeater cabinet moved to the new site and connected everything up and threw the power switch to ON!
As usual, it was not without its hiccups. Although everything had checked out before installing, the reflected power was high. That was resolved to a bad connector and remedied. Then we found that the control receiver was not working … that was a bad 1-amp fuse.
Finally, everything was up and working properly. We left well enough alone and wrapped up our endeavor for the day. We’ll go back and take care of grounding and cable dressing shortly.
It’s really nice to hear the repeater back on the air. Actually, it has been operational, but with limited range due to compromises with the antenna height. Now, with the antenna at a decent height, it sounds great.
There’s been progress on the W4MT repeater installation. As you may recall, the antennas went onto the tower a few weeks ago. Yesterday, we were able to check the feedlines and both the main and backup antennas were well within tolerance. Later this week, we’re going to clean the equipment room at the site, move in the equipment, and get everything connected up and on the air.
Maybe by next week both repeaters will be on the air (fingers crossed)!!
