warren, very nice work to answer a very crucial question....

so it's time to see if the relay can be

a) altered so as to be improved? (move wires, add shielding, to existing relay type)

b) replaced in some easy fashion (different device, or even?"replace" it by adding additional circuitry to move half the function to a different physical location)

Also reasonable to consider

c) given that there are FOUR relays, how can one cleverly reroute physical signals (board changes) and software changes so as to get X bands working, where none of the inputs pass near the outputs on a single relay???

In other words, for(c) you can reroute signals somehow and achieve at least TWO working bands, and possibly MORE by being more clever than I generally am....can someone see how to get THREE or FOUR signal paths working?? ?

Adding a manual switch of some sort would certainly also be a possibility!? ?

But MY goal this week is to give a nice tutorial to our ARES group on how to load up the IDE, and how to capture software upgrades to bitx-type products and load them onto these little critters, and a tiny bit of how to alter the code yourself as well......in preparation for our beginnning to "build" these devices on August 18th.

Cheers,
