Troubleshooting & Aligning KE4COL 145.230 Mastr II Repeater
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 […]
Gold Hill DMR Repeater – Further Additions and Improvements
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 […]
Looking Forward To Watching This Thing Go Up
Gold Hill 442.175 MHz DMR Repeater Back Online After MOSFET Replacement
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 442.175 Repeater Down Temporarily and East Central AL DMR Talkgroup Update
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 […]
STM32_DVM to Yaesu Fusion DR-1X Interface Instructions and Wiring Diagram
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 […]
