====== Ham Radio ====== Studying for an FCC amateur radio license in 2025. By recommendation and for some pre-existing familiarity with digital and electronic concepts, I am aiming to take both the Technician and General levels at the same time. This opens up more of the HF bands for use. After a few ARRL books from the library for background, using [[https://hamstudy.org/]] to practice test. This also confirms that the further Extra license is out of my reach without a lot more study. Following #HamRadio on [[Fediverse]] has given a scattered sense of global uses and interests. ====== Resources ====== [[https://www.arrl.org/images/view//Charts/Band_Chart_Image_for_ARRL_Web.jpg|ARRL Band Chart]] ([[http://arrl.org/graphical-frequency-allocations|or in other formats]]) [[https://www.arrl.org/files/file/Regulatory/Band%20Chart/OTAbands.pdf|Vertical OTA Bands PDF]] [[https://wiki.m0aws.co.uk/|Open Source Software in Amateur Radio wiki]] [[https://qrper.com/2022/07/choosing-a-field-radio-how-to-find-the-perfect-transceiver-for-your-outdoor-radio-activities/|Choosing A Field Radio (QRPer)]] [[https://www.essexham.co.uk/ft8-basics-explained|FT8 Intro]] and [[https://www.g4ifb.com/FT8_Hinson_tips_for_HF_DXers.pdf|FT8 manual]] Propagation Maps: [[https://hf.dxview.org/perspective/EM82jx|HF DXView]] and [[https://vhf.dxview.org/|VHF DXView]] ====== Blog roll ====== [[https://www.zeroretries.org/]] [[https://km1ndy.com/]] [[https://www.onallbands.com/]] ====== Contests ====== [[https://pota.app/#/map|POTA map]] [[https://cqparks.net/|CQParks]] ====== Radio Kits ====== [[Ham Radio Kit Comparisons]] [[https://qrpguys.com/qrpguys-digital-fsk-transceiver-iii]] [[http://qrp-labs.com/qmxp.html]] 5W CW/SSB/DIGI or [[http://qrp-labs.com/qdx.html]] 5W Digi only as a kit.
