There are a whole bunch of nets on the air. On 80 meters I usually check into the Wolverine SSB net (Michigan and surrounding states usually) the pre-net starts around 6pm Eastern (2200 hours UTC) and the formal net one hour later.. Winter hours are the same UTC (an hour earlier eastern) Frequency 3935
Then over night there is the Before Breakfast club and Breakfast club. Pre-net starts informally between 1 and 2 am Eastern (Summer and winter) formal B-4 starts at 3am, runs to 5am when the Breakfast club takes over till 8am, 3973KHZ.
And there are other nets including the FMCA net 3pm eastern at this time (not sure of the frequency as it was not where I expected it)
If you don't mind typing instead of talking you can go DIGITAL using a program called Ham Radio Delux or several others.. My "Arsenal" of software includes HRD, (With DM-780) which is rapidly becoming my first choice.. Hamscope (My former First Choice, has the best user interface for Macros) and Digipan (Has a few features that prior to DM-780 nobody else had.. Namelly a "Multi-Chan receive)
Using a simple home made interface (HRD comes with instructions to build one nearly identical to the one I designed) I"ve worked about half the world on about 30-40 Watts PSK-31 assorted bands all hours.
My primary HF antenna.. On the rear of the motor home is a Kenwood KAT-1 (Marine Grade automatic long wire tuner) hooked to it is one end of a 100' wire. There is a tie line to a eye bolt at the roof line a few feet out (strain relief)
The other end of the wire is currently anchored to a Sunsetter push-up flag pole, it forms one of 3 guys (Since I don't expect the pole to support the pull of the wire) Next "incranation" I will replace the flag pole with something else,, I'm going to try a group of 4' "Painter's Extension Handles" chined to the 16 or 20 foot level.. WHY? Well,, I have other uses for the flagpole.
VHF/UHF.. There is a program you can get from the ARRL store
