Said I have to say I was looking through the list of modules that are available. I guess a couple of things really jump out. The low power consumption and what you get in terms of behaviors. It is pretty amazing actually. Though I have my power sucking Tbolt and 3801. But I could easily see for a Amateur radio operator just getting into time nuttery that these might be a nice way to go. I guess that would open an interesting debate. Getting the used RBs at Hamfest of questionable quality for $200 or far less. Or something modern and simply works. Regards Paul.
