KD1JV / Steven Weber OM が QRPguys.com 向けに設計中の機器 [QRP]
Groups.io に KD1JV / Steven Weber OM が QRPguys.com 向けに設計中の機器について書いています。
３つ程、設計しているそうです。
1) New FT-8 transceiver. This one can cover all bands 160 to 10M with 5W output and is single signal, and yet is very simple. Same size as the current DSB FT-8 version. I’ve been having fun testing the heck out of it. 40 and 20 are just so busy it’s hard to compete. I’ve had the most luck on WARC bands. I’ve been amazed by how much DX I’ve worked on 60. My “88’ doesn’t load real well on 30M, but does reasonably well there too. Worked some DX on 17M Saturday and even made a couple of 160M contacts.
2) A three band CW transceiver for 15, 12 and 10 meters. Get ready for the next sunspot cycle. Stock version is crystal controlled with VXO tuning for receive. Single output filter optimized for 10M (5W output on 10, 3W on 15) Optional digital VFO can be plugged in for full band coverage. (same as used with the FT8 rig, but requires different firmware)
3) Digital RF power/SWR meter with built in dummy load. 10W full scale. Three digit LED display, runs on a single CR2032 coin battery.
で、注目なのは１）で
It will work with all FSK modes. It won’t do PSK31 since audio tones are measured and added to the VFO frequency directly by the processor, eliminating the need for mixing and linear amplifiers. A very cleaver technique developed by AG6NS.
と補足があります。
AG6NS は 寺崎 和久 OM で、uSDX の極座標変調を CentSDR に移植された方です。
期待が膨らみます。
