The stock antenna on my Baofeng UV-5R stopped working just before a vacation trip up north. This got in the way of operating in the Upper Peninsula, which I had been looking forward to. Oh well, several the repeaters up there have Echolink, so any time I want to tune in I can, as long as I have wifi or cell data coverage. I didn't go on the air while I was there, though I did monitor one conversation (about snowmobiling).
I've replaced the Baofeng's antenna with a Nagoya NA-771. It's quite a bit longer than the original equipment, so much so that it just barely fits in my bookbag. It still does fit, though, and that means I can still carry a radio around with me anywhere. I haven't done exhaustive trials of performance but it's clearly better that I had been getting before, and overall I'm happy with the switch to a new antenna.
It was a busy night tonight on the N8DUY 145.15 repeater as storms blew through the area causing widespread power outages and lots of talk on the Skywarn net. Even though there was a lot of static, I still was able to hear the talk on the air and relay reports from trained spotters to Twitter. (I'm not a trained spotter yet - yet! - so I didn't check in to the net.)
