Ham radio was hot at HamCation 2022

Amateur radio videos: (tr)uSDX by Dan KB6NU Feb 18, 2022 So, a couple of days ago, a guy in our club posted to our mailing list that he was thinking of starting a group buy for the (tr)uSDX transceiver and included a link to the video below: Here’s a description of the little transceiver: The (tr)uSDX is a 5-Band / Mulitmode QRP Transceiver in Pocket Format (90x60x30mm – 140g). It features a highly efficient Class E PA and Supports CW/LSB/USB and AM/FM. Right now it covers 80/60/40/30/20m and in Future there will be support for 17/15/12/10m as well. It is supplied with an OLED Display, onboard Mic, (tiny) onboard speaker and for improvised QSO onboard PTT Key can be used as emergency CW Key. Further on, the (tr)uSDX has a (Micro)USB CAT and Programming Interface, and while it produces typically 5W @ 13,8V Power Supply, it can create 0,5W Output from 5V USB Supply alone. Typically it draws 80mA on RX (with MS5351 – less with Si5351) and 500mA on TX @13,8V and typical 85% PA Efficiency. It is supplied with OnBoard SWR Bridge and Voltage/Current measurement Hardware, to help in tuning and operation. Talking about the on-board test equipment, here’s a short video on how that works: The guy says that if we do a group buy, they’ll cost about $60. That seems pretty cheap, since in single unit quantities, they’re selling for closer to $100. Here’s a video of the designer unboxing a kit from one of the Chinese suppliers: I don’t know where the guy is going to be making the group buy, more than a dozen club members have signed up so far. I need another project like I need a hole in the head, but I’m going to get one, too. The post Amateur radio videos: (tr)uSDX appeared first on KB6NU's Ham Radio Blog.
