It seems many QRP radios and kits, which are designed to be operated in spartan conditions and powered by a small battery, are still designed to operate at full power when the supply is 13.8V.
I have an MFJ-Super battery booster to use with my IC-7000 and it works great as long as you use the RF sense feature, but I was wondering about something much smaller. For $12 this can be purchased on amazon: http://www.amazon.com/3-5-30V-4-0-30V-Booster-Converter-Regulator/dp/B008FLE7PA/ref=sr_1_1?ie=UTF8&qid=1371930970&sr=8-1&keywords=voltage+booster
It is good for 3 amps continuous or 5 amps for shorter duty cycles. Does anyone see a problem with using something like this for a five or ten watt radio?
Thank you very much,
