Started getting my stuff out today and thought some of you may like to see my DiY caller. It's a 12volt amp wireless mic and horn In a camo bag. I power it with a 7ah battery that runs it for a Long time between charges. Excellent wireless range and very loud. I plug the transmitter into an iPod that I have my calls loaded on.
Man, hope those surgeries heal fast and do the trick for you! That's why I haven't been out much this year too - not that I've had surgery, but that I probably should have already, was hurting so much I couldn't do anything for a couple months. Managing it with steroids right now, but that train ain't going much further.
I've been really happy with how fast I have been recovering I should be close to 100% by my second surgery
