So the lab599 Discovery TX-500<\/strong> I’ve been testing the past week has been sent to Ham Radio Outlet<\/a>. Over the course of one week, I activated eight parks with this QRP transceiver and if I’m being honest, I miss it already. It’s an awfully fun and incredibly robust\u00a0 field radio.<\/p>\n

On my last outing with the TX-500 (last Wednesday) I did an activation of the Blue Ridge Parkway and Nantahala National Forest. I operated CW and SSB and worked stations from Maine to Ontario, Illinois to Iowa, and Louisiana to Florida running 10 watts into my trusty EFT Trail-Friendly antenna<\/a>.<\/p>\n

While I’m evaluating radios I take lots<\/em> of notes so I can remember detail when writing my review. In the field, I often take short video notes as well.<\/p>\n

While finalizing my TX-500 review for the October 2020 issue of The Spectrum Monitor<\/a> magazine, I rediscovered the following video note. I made this with my iPhone and assumed I might<\/em> include a link in the TSM article. In the end, though, it was really a journal note for my review.<\/p>\n

I thought I’d share it here for those who are considering purchasing the TX-500 and are curious how well the receiver handles dense RF environments. I had the CW filter width set to 100 Hz–had I intended to publish this video I would have likely cycled through various filter settings.<\/p>\n
