Re: uBITX V6
Hi Art, Getting the T/R output from the Arduino does not work for you? If I remember by heart, it is the first pin on the Raduino connector (to the radio). Rafael

Re: Difference between a ubitx ver 5 and 6
So if I find a ver 5 with a 16x2 LCD it¡¯s basically a ver 6 with the older two line display. I found a ver 5 deal. Just wondering if I¡¯m missing something. Thanks 73 John N4HNO

V6 moved to colour display. Same features, now in colour! Just imagine... you can set usb/lsb/cw in colour! Amazing.

Re: DHL
I don't know if DHL has a fleet of cargo rockets, but time like this seems typical for them.? I had a package at my apartment door 50 hours after it was picked up, and I am in Winnipeg, MB, Canada
