So, the USB/Serial cable arrived yesterday. Last night, I downloaded the Utility software and reinstalled the firmware 5.50. All was good, no issues. So I decided to try the Beta firmware 5.52 and again no problems and the radio behaved normally so I was overjoyed. I sent an email to Elecraft, expressing my jubilation that the matter has been resolved. Fast forward to this morning. I started work this morning at 0800 but was up early so thought I would have a tune around before leaving home. To my amazement, the radio behaved as it did before my interventions last night. Jumping bands, random relay clicks and the frequency readout displaying weird frequencies such as 249Mhz... I did shoot a quick video on my phone, again, and its on YouTube here:- https://youtu.be/Lwuuy246FyI <https://youtu.be/Lwuuy246FyI> I apologise for it being on its side but it was early! I now fear this radio is going to have to go back to the dealer (Waters and Stanton (UK)) for repair / replacement / refund. My Elecraft experience has not been as I had hoped, being my dream radio.
