I had bought a couple of the new mini TXCO's when I bought my QCX+ but never used them. After reading Tony's note it reminded me to install one on one of my U3S units. Did that today and this little T

QCX+ is SOLD Vernon

Hi.. I have a new in the box, untouched, 20m QCX+, TXCO, and matching case for sale for $115 CDN funds. This was my cost excluding shipping. My location is Truro, Nova Scotia. I would prefer to sell i
