📡 #HamChallenge2025 Week 16: Make a contact with a xOTA station @hamchallenge

Just worked VP2VI 🇻🇬 on 12M #cw with my vertical and barefoot 100w. Consider the IOTA NA-023 as HC16s but will try to find SOTA or POTA on 40M later.

Been having fun with #HamChallenge2025 https://hamchallenge.org/
HC16S Make a contact with a xOTA station. Ran across AB9CA on 20m CW. Heard CQ POTA so gave him a quick call on 14.053 MHz. Was not sending park info, so checked POTA app and found him listed at US-1095. Conditions fair but completed contact. 2017 UTC, 3/18/25. ~17 WPM CW. @hamchallenge

#HamChallenge2025 @hamchallenge HC12S Make a contact on an unusual antenna. How far can two Yaesu VX8-DR HT’s communicate on L1 (20 mW) transmit power with dummy load antennas? Turns out the answer is about 12 feet on UHF. Was surprised that the shielding was that good…

L1 (0.02 W, 20mW)
