My loop antenna is a simple resonant circuit: Consisting of a loop of copper connected to a variable capacitor. A smaller matching loop inductively links the transceiver to the larger copper loop so the radio see the right load.
Seems I didn't learn my lesson with cheap coax ... The short piece that connects the wire matching loop to the longer cable run was a piece of RadioShack brand with a PL-259 connector conveniently attached. As I started started to transmit I noticed the SWR (Reflected power ratio) start to rise the longer I transmitted. As soon as I stopped for a moment it quickly dropped so I knew that whatever was getting upset had to have a fairly small thermal mass ... it wasn't the tuning capacitor for sure! I'll have to swap out the short piece of coax for a SO-239 socket and run my good coax directly to the antenna. While I was testing and making a few field day contacts I kept the power level low which kept the SWR under control.
Tonya added her baked creations to the Field Day menu and I suspect we may have beaten last years time in consuming everything apart from one slice of apple pie which lasted until Sunday morning. We were extremely well fed with delicious food thanks to many contributions with special thanks to Mike N5TGL and his wife who hosted the event and tolerated our impromptu lectures and animated discussions of ham radio miscellany for the two days of Winter Field Day.
The Society for the Preservation of Amateur Radio is the organizing body that schedules this event for the last full weekend each January. The object of the event is familiar to most Amateur Radio operators: set up emergency-style communications and make as many contacts as possible during the 24 hour period. The rules encourage as many contacts on as many bands and modes as possible, because during a real emergency, the most important factor is the ability to communicate, regardless of band, mode or distance.
