This last week I was able to spend some time in Sequoia National Forest and activate a few peaks in between fishing and typical camping activities. I was actually able to activate two previously unactivated peaks, which I might write a summary on later.
My question to the SOTA community is about the MTR5b. On my last activation, I sent out a spot, and pressed “RIT” and “M1” to send my preprogrammed initial SOTA CQ message to hit the RBN; however, the unit somehow went into a kind of beacon mode.
Because I didn’t have the manual and I didn’t know how to stop the beacon, I powered off the unit, and attempted to turn it back on. When I flipped the power switch back to the “on” position, the screen remained blank but the backlight came on. I then disconnected the battery and reconnected it which resulted in the same effect.
I tried to drain the capacitor memory by leaving the unit in the “on” position with the battery unplugged for a few minutes on the summit, but the unit would not display text or allow any kind of manipulation, so I completed my activation with my HT on VHF.
On the drive back to the camp, I left the MTR in the “on” position, and battery unplugged. About two hours later, I then turned off the MTR, plugged in the battery, and turned on the device and things seemed to be back to normal. Of note, the only other difference than a longer time delay was an increase in temperature from about 45 degrees to around 60 degrees F.
Just a FYI I also launched an email out to LNR to ask if powering down the MTR during a memory recall function is something that shouldn’t be done or if this is a problem. I re-read the manual as well and didn’t see anything in there that referenced a hard reset.
Thanks in advance for any info on this! It was kind of a challenge to work through the problem on the summit, but thankfully I always pack a HT as a backup & got some locals and a mobile station that were up early and monitoring.
