Happy to make contact with you.

I obtained Technician and General Licenses in July 2025 so I’m new to amateur radio.

Free, open-source amateur radio web apps I’ve created:

[Grid Explorer]: Load your ADIF file and view your contacts on a world map with bearing, distance, grid/station summaries, and geodesic paths.
[adi2kml]: Load your ADIF file and receive a KML file to use with [Google Earth]

My current radio setup:

HF Transceiver [Hermes Lite 2]: An entirely open source and open hardware low-cost direct down/up conversion software defined radio (SDR).
SDR Software [piHPSDR]: An open source program that operates the Hermes Lite 2 transciever; it’s well-written, easy-to-use, and full of features.
Amplifier [60dbm.com 100W Neptune]: An outstanding auto band switching amplifier from Ukraine. I was so happy with the amplifier I purchased their [RF sampler] to setup adaptive digital predistortion (aka Pure Signal).
Antenna [MyAntennas.com EFHW 4010-P]: A tuned, portable, end-fed halfwave antenna the covers 40/20/15/10 meters deployed in a [sloping configuration] around 7 meters up a tree in my backyard.
Network Analyzer [NanoVNA]: An open source and open hardware handheld vector network analyzer (VNA).

Logging

I use [QLog] to upload all QSOs immediately to [QRZ], [Clublog], [HRDLog], and [LoTW]. Thank you for confirming your contact with me. You can [view all my current contacts] (and yours too) in Grid Explorer.
