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 […]
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 […]
If you are interested in hooking up one of Scott Zimmerman’s incredible STM32_DVM multi-digital mode controllers to a Yaesu Fusion DR-1 or DR-1X repeater, then I have produced a webpage/article and information which was written for you; moreover, if you want to create an interface that is sure to work well and adds several other […]
If you would like to see a ton of real-time status information on the 442.175(+) Gold Hill, AL KK4ICE DMR Repeater, you can do so by just going to the KK4ICE Repeater status and info page on the Brandmeister Network. Just some of the information you can see on that page is a list of […]
As of 5/24/18 the 442.175(+) Gold Hill machine has been changed to full-time DMR operation. It is working fantastic and a bunch of us are enjoying having nice, clear DMR QSO’s using handheld radios to actually go through the repeater direct from distances we were not able to when it was running as an analog […]
With a little help from a fellow ham, I’ve finally ventured into the world of DMR digital amateur radio. That’s one of the wonderful things about this hobby: there’s almost always a fellow ham who has knowledge to share in a particular area (and has already discovered and resolved many of the annoying technical issues.)
