Why did I ever trade my HR2510 for a Garmin Etrex for APRS? I wish I still had it. The HR2510 was a lot more useful and fun than APRS.
The really good news is that this is b no means a permanent situation.
How many HR2510s are out there somewhere?
There may even be someone just chafing to trade one for a Garmin Etrex, too.
You never know what you can do until you try.
