Well, Dave, your observations have caused me to take a second look at the K3(S) with transverters for VHF/UHF weak-signal work. The only problem is, an amplifier to bring the 2m power output of the 2m option for the K3(S) up to 120w or so is around $650 (looking at Mirage) and 120w is not all

Re: [Elecraft] K3 Digital Voice Mode - our future?

There are advantages to digital voice, but for Amateur Band use, I don't think we are "there yet". When we see an 'open source' digital voice mode that is published and can be implemented by any amateur, then I may change my position, but that is not the situation today. I do not believe

Re: [Elecraft] Product Suggestion - 500W Dummy Load

Some non-inductive resistors do not have the coating that protects from the oil. Those will rise in resistance over time. This article has more than you ever wanted to know about the Cantenna and modern equivalents. http://www.orcadxcc.org/content/cantenna_va7jw.pdf

FreeDV is open source. You can use the FreeDV API (http://www.rowetel.com/blog/?p=3469 ) or get a box that will implement it and can be updated with new protocols (http://www.rowetel.com/blog/?page_id=3902 ). Or

Just to make sure we carry some Elecraft content you might like to look at the following URL's http://www.rowetel.com/blog/?p=4584 http://www.areg.org.au/?p=1719 And the code for both the Codec2 and FreeDV is freely available here; https://github.com/freedv 73 Matthew VK5ZM On 18 September
