The KE4COL 145.230(-) Gold Hill / Auburn, AL repeater is back to running on a Harris Mastr III machine. I spent Saturday, 2/9/19 reconfiguring, reprogramming, and realigning this machine for Lee (KE4COL) and he transported it to the repeater site and fired it up on Sunday, 2/10/19. There were a few audio drive/distortion issues on […]
The number of registered DMR users is still growing rapidly. Interest in DMR is definitely not waning. In fact, I’d love to know just how many folks bought themselves their first DMR radio (or were gifted with one) for Christmas. It wouldn’t surprise me to see a surge in the number of new registrations for […]
Now that it has been running so well for almost three months, I made the decision to keep what was built as a “temporary” repeater for the 442.175 DMR machine as the “permanent” machine. It’s doing its thing at about 93 Watts with no problems noted, so — as they say — “If it ain’t […]
I wasn’t sure when I’d be able to do so due to increased physical limitations lately, but with some assistance from a wonderful friend (“Thank you, KD4BO”) I was able to put the temporary replacement DMR repeater setup online at the Gold Hill, AL site yesterday (July 24, 2018.) This is an interesting repeater setup […]
A case of “Well, that didn’t go quite as planned” KE4COL and I met at the tower site Saturday morning to put the 145.230 Gold Hill machine back on the air and discovered a desense problem. Yes, a bit of cussing ensued, but not at one another — just in general, shared frustration. So […]
Just a little update on what’s happening with the KE4COL 145.230 Gold HIll repeater repairs/testing, and a few other cool things going on lately. KE4COL Mastr II UHF Appears Good To Go Back Into Service The 145.230(+)123.0 VHF Mastr II continues to behave well here in the lab since I serviced and realigned it […]
Last Friday, we pulled KE4COL’s Mastr II 2-Meter repeater out of service due to some intermittent “crashes” on COS drops, strange noises, etc. which had been occurring for a while. I brought it here to the lab and finally got around to going through it today. I found and addressed a few issues and it […]
The Gold Hill, AL 442.175 MHz DMR Repeater got a few additions and performance improvements today. For starters, I added a combination of an EMR 5-Cavity UHF Preselector and an EMR Preamplifier to the receiver side of things. By doing so, I boosted the receive sensitivity of the repeater by 14.57 dB and at the […]
The Gold Hill, AL 442.175(+) KK4ICE DMR Repeater went back online a little around sunrise on Saturday, June 9th, 2018. Following replacement of the burned-out MOSFET power amplifier chip, the repeater was reinstalled with an external power amplifier connected in order to decrease the load on (and the heat inside) the DR-1X repeater’s transmitter radio. […]
Gold Hill, AL 442.175 Repeater down for a few days due to PA failure Apparently things over on timeslot 1 were really, really busy this past Saturday night. The dual-pack MOSFET final transistor in the transmit radio in the Yaesu DR-1X repeater… well, we “let the smoke out of it.” A replacement transistor is on […]
