Jerry VE6TL at the University of Calgary Amateur Radio Club Welcome to my Arduino Ham Radio Starter Kit, a “virtual box” of ideas and motivations with one objective: More hams and their clubs engaging the local maker community as a gateway to amateur radio. First of all, let’s think about the three waves of technical hobbies over…
DetailsIcom IC-7300 HF/50 MHz Transceiver – wide band modification. 1. Check the radio to be disconnected from power supply 2. Please, use ESD discharge measures! No kidding, use ESD countermeasures both for your body and for the soldering station! 3. Use a lot of soldering flux! The diodes are very sensitive to high temperature and…
DetailsThe K9AY is terminated loop. It consists of a wire loop of any convenient shape (diamond, delta, etc), hung from a single support and with a ground rod at the bottom. A 9:1 impedance-matching transformer is connected from one end of the loop to the ground and terminating resistor is connected the other end of…
DetailsWeekend VHF QRP FM transceiver is an Open source project that was started by Jure, S52CQ in March 2015 when he started using DRA818 in his transceivers. He has made many variations/modifications since then and now the Weekend project is a nice project for HAM novice operator that within a weekend makes his first…
