QRPX Army NETCOM Annual HF Low Power Competition

Hello operators.

I thought this would be an interesting post to share. It’s always nice to see amateur radio equipment being used in “real world” scenarios. Not having previously heard about the event, please bare with me, my contribution will be short but it will be a good read!

About the author
CW2 Anthony M. Jaber is a Signal Observer Coach – Trainer (OC-T) for NTC Operations Group, Fort Irwin, CA. He is active duty Army with 17 years of service as a Signal Corps soldier in the MOS 255A – Information Services Technician, and as a 25B Information Technology Specialist while enlisted. He is a General Radio Telephone Radar Operator License with Radar Endorsement (GROL+Radar) holder and Amateur Extra Class Amateur Radio Operator.

CW2 Jaber details his experience researching, building, then deploying a capable portable station for the annual QRPX event. He had to contend with a variety of real world problems low power stations are forced to deal with, when operating in harsh environments, contending with noise, and competing with the “big gun” stations. This operators experience and his sort of “after action report”, goes through the equipment used, how it was setup, how it could be improved, and the results of that equipment in regards to performance and practical operation during the QRPX event.
