The receiver is solid and the built in tuner works like a charm. I would recommend this kit to anyone with more than one or two kits under their belt. You will have a very good time using this radio in the field. Another built in advantage is the color. Many scoff at the bright yellow enamel coating; but as a side benefit, the radio does not get hot. The dark gray case of the K1 can heat up the radio and cause it to drift in the hot sun, Not so with the PFR3A. All in all, I am very glad that I ended up not selling this radio. It will not replace the K1; but it will get used.
I am going to ditch the doublets as part of my portable operating antenna arsenal. From now on it will be the Buddistick and maybe an end fed wire. Doublets and dipoles are ideal for a camping set up, where you might be situated in a base camp for a few days to a week. For just a couple hours of operating, they are more a pain than it's worth. The Hamsticks will also remain a part of the scheme when operating solely from the back of the car. My kind of outings are very temporary in nature. I want to get set up and get in as much operating time as possible.
