I initially tried using a stopwatch to keep an eye on my time, but it was just too difficult for me to manage (as our net includes a lot of participation by Net Control - answering questions and so on). When you are running net control, there's a lot going on, and I think trying to manually manage two timers (while also operating the radio, logging/tracking operators, etc.) would be too much. I plan to change to monitoring the PTT signal from the microphone to get around this. It may also be RFI from other devices causing this. and what IS the question toggle quoted message Show quoted text On. 73, Robert (KO4JHZ) More All Messages By This Member Robbert J. The display format can be set to 12 or 24 hours. It simultaneously displays local and UTC (GMT) time. I'm currently (ha!) having problems with the current sensor I'm using - the system is somewhat randomly thinking that radio is transmitting when it is not. MFJ-148RC Robert 29473 I have a question for users of the MFJ-148RC clock. The huge MFJ-148RC dual time zone clock is optimized for amateur radio operation. When I ID'd, I would manually press the button which would clear/reset the ID timer (until the next time the radio transmitted). When the radio switched back to receive, the time out timer would automatically clear/reset. Initially, the displays would be blank, but when the radio transmitted, each would display a countdown timer - one for ID and one for timeout. This would allow me to determine whether it was receiving or transmitting so I would not have to manually do anything. My idea was to sense the current to the radio. I used these displays primarily for readability (bad lighting/eyes for something small like your typical 2- or 4-line LCD displays), as well as to be able to show letters (I display a flashing "-TO-" and "-ID-" when those timers expire). I'm using a spare Arduino Uno, two 4-character alphanumeric displays ( ), and pushbutton, and a current sensor. I wanted something automatic that I could connect to my Kenwood D710 that I operate in the shack. But once the clock was synced, it worked flawlessly. He sometimes had to wait TEN HOURS to get his clock synchronized. HT or mobile/base radio, operating handheld, vehicle-mounted, or desktop, etc.), but I've been working on a project using an Arduino to track the repeater time out and ID times. I have a friend in CA that experienced similar problems with his MFJ-148RC. I'm not sure what your operating conditions are going to be like (i.e.
