After assembling a solid set of QRP gear this year I wanted to put everything into an easy to transport package. To house and protect the kit I used a Monoprice 13″ x 12″ x 6″ Weatherproof Hard Case. This case is the perfect size to fit my mcHF transceiver, and Elecraft T1 autotuner, along with a 3″ external speaker, hand microphone, and power cable. All together the case and equipment weigh a little under 7.5lbs.
With this kit, all I need is 12VDC power and an antenna and I am on-the-air. This should pair perfectly with a small battery and either my random wire or end fed half wave antennas that I built recently.
Update (March 2017)
After completing my mcHF’s new case I decided to update my mcHF Field kit accordingly. Since the new case has an internal speaker I was able to eliminate the external speaker from the kit. In its place I put a 6Ah Lithium-Iron-Phosphate battery. This should give me between 6 and 12 hours of runtime at 5 Watts output, depending on how much I transmit and what mode I am using. While more expensive than sealed lead acid batteries, LiFEPO4 batteries are lighter in weight, smaller in size, provide more usable amp-hours, and last many more charge-recharge cycles. This 6Ah model weighs about 1.75lbs, compared to 5lbs for a 7Ah sealed lead acid that actually provides less usable power. This iteration of the kit weighs a little under 9lbs, over 3lbs less than the previous version (including the lead acid battery) and it is more compact as well.
