There are a number of G-50s about, but very few G-28s. It took me years to find a good Gonset G-28. I know of two others in use in New England. It is great to see there is interest of getting on 10 meters AM. Sometimes, I monitor 29.0 MHz.....Remember Ozona Bob, W1PYT? Talk about old buzzard transmissions, but he always a good signal out of Texas. When 10 is open, I have heard a dozen AM QSOs going on between 29.0 and 29.1. It's worth trying!
