Having an issue with the 3.619 alerting, and becoming stuck, on laser alert. Power cycling helps for a minute or two but it goes into full alert again. Also have some burnt out LED's. The 3.818 just needs a tune up, seems a little "soft" to me and has lost a bit of it's edge since I last sent it in a few years back. At the minimum I want the $45 tune up on both. I'm the original owner on both of these and have sent them in a couple times over the years. On the V1 upgrade proposal page both units are estimated at $139. This would give me PoP and Euro on the 3.619 and Euro only on the 3.818. I was thinking perhaps of doing a full update on the 3.619 to the current standard and making that my main V1 and doing a tune up only on the 3.818 and moving that down to my secondary V1. Price is not an issue... performance is. I've read that some older versions preform better than the current releases but 3.619 is pretty damn old! If I do tune ups only what firmware versions would I likely end up with? Thoughts?
