Sadly, I decided to replace my Alpha 8410 in January 2021. While it was a 9.9 on a 10 point scale and effortlessly put out 1.5 KW or more on all bands, I decided that a) instant QSY was important to me, and b) the cost of replacement tubes “someday” was too high for my comfort. The replacement is an Elecraft KPA1500 and although its use spans a mere 24 hours, “I love it”. Great engineering, feature comforts, and excellent performance, especially when married up with an Elecraft transceiver.
Mid-November 2020 completed the addition of three Caribbean-oriented yagis on the 90 foot tower. Through the use of remotely controlled 1 x 2 transfer switches, RF is instantly channeled to these SE pointing antennas when needed; no antenna rotation required. The yagis cover 10, 15, and 20m. They worked flawlessly in CQWW CW 2020. A writeup is included in both Scribbles and Power Point Presentations sections.
Unfortunately, my Orion II has developed several problems; the master TCXO wants to wander outside its calibration range and there have been several instances where intermittent issues have shown up in the baseband processors. I am going to miss this radio that has served me well for 12 years.
The new K3S is just an updated version of the K3 which is already present. Some differences in VFO phase noise, less distorted audio, etc. are in the new K3S design.
