I'm always evaluating new modes for emergency comms for our local ARES group, and one of the ones I want to better understand is ALE (automatic link establishment) --- which might benefit y'all's attempted bitx communications, by the way.

So today I hauled one of my Raduino's to work where I have a bit of time to fiddle.? ?It is one that is a standalone, configured to drive a boatanchor (EMP-proof) Heathkit SB-100, but other than that, it looks like any Bitx and is loaded with one of my sketches, branching off from Allards excellent 1.24 version.??

To which I had added FT-857d emulation, to allow computer controlled frequency selection of the Raduino.??

I'm quite pleased to report that the PC-ALE software when told to drive a "FT-847"? (closest available choice) appears to work FINE with the stuff I wrote, and so it would appear that we would be able to drive a BitX40 just fine (on one band) and would eventually be able to drive a uBitx on MULTIPLE bands, presuming that your antenna was capable of immediately working on each band.? ?(The latter can be done by any of several means: multiband trap or parallel dipole/ multiband vertical / auto-tuner that has memorized settings for multiple bands, etc etc etc.)

I am attaching a file of a screen grab of the PC-ALE software installed on my windows computer and "driving"? a raduino that it thinks is a Yaesu 847 radio.? At present I have only two scan frquencies installed, but the Raduino is happily flipping back and forth between them, sitting here on a desk before work starts.? ?

?? ? ? ?link to download the PC-ALE software.? ?You have to grab a frequency file appropriate for your part of the world and follow various directions to load it.

The PC-ALE stuff appears to need some sort of a soundcard interface, such as a Singnalink (or the $25TNC that our local ARES group has built a bunch of.....)? ?and I've used Signalinks etc many times successfully with my Bitx40''s --- just remember that the Signalink has a dead-dc-short transformer output, so put a 1 uf capacitor in the mic lead to dc-uncouple.? ? The Signalink output relay successfully drives the relays in the Bitx40 quite well.? ?My reed-relay outputs from homebrew interfaces were not always as successful.

Cheers!

P.S.? And yes, this kinda stuff will go into the 3rd edition of the little book I wrote on emergency communications for hams...
