Re: Tuner? Well Sure!

It is a kit, right?

Give me both choices.  That is, sell the kit with the constant current draw relays, but design the board alternately accommodate the latching relay footprint.  Then I as the kit builder can buy the latching relays and fit them if that is my need.  Just don't forget to tell me which relay model you designed the board for.

Now my question to the group is this…  would you rather have a very functional tuner but draws additional constant current…. Or a tuner that draws very little current once tuned but is $65 more expensive?  I don’t do too much battery operation myself… but I am sensitive to those who do.  If every relay were engaged (not likely) it would draw 1.2 amps total (60ma each).
