[600MRG] License class + Background information

Pat,
Welcome to the hot weather and static in the south.
For background information you should start with the www.500kc.com site. 
We have posted whatever we found that helped there. There are links all around. 
The technical files are going to be very valuable if you are not a former broadcast engineer or 160 meter antenna specialist.
After a week or so reading the technical files you should go to w5jgv site and see his 166KC experiences like burning antenna insulators which can't happen on higher frequencies because the positive and negative peaks of the RF cycle are too short duration to arc over at HF. 
Our EIRP limit for the first few years won't burn insulators, but the same losses raise noise level and reduce signal.

The books we used are hard to find so scans are there. Take a full day on the low-frequency antennas book.
Remember to consider the old folks listening to soothing easy listening AM radio and the unhappy talk shows. 
Figure your second and third harmonics will fall right in the AM band where broadcasters call the FCC directly. 
There are good designs for low-pass filters at www.500kc.com and w5jgv.com.
 Putting the low pass filter at the antenna end of the coax will protect your receivers from picking up overload from the local AM stations.
If you ever listened to AM radio at night, you have experienced stations skipping in and then skipping past you. Your signal will do the same based on the position of the sun. Plan your QSOs for the skip distance you learn.
A good shielded receiving loop will make a lot of help on receiving noise elimination.
High noise levels and narrow filters restrict the CW speeds to 15 wpm or less unless you are talking across town.

Hey everyone!I am Pat Brown KL3DB and formerly in Alaska. I have just moved to Texas near Dallas region and now interested in this branch of ham. Is there background information so I can get up to speed and a bit of licensing for these bands?Pat

Bill,

I have operated a 10 meter CW beacon for a bit more than 10 years now. 
For the past 3 years it has been QRP (275mW) and dual-mode, transmitting 
both CW and WSPR. Depending on time of year and conditions, I get 
anywhere from 5 to 200 WSPR spots per day but only 3-4 CW spots per YEAR 
despite the fact that is spends 80% if its time sending CW (8 minutes 
CW, 2 Minutes WSPR).

I realize that no comparisons between 10 meters and 630 meters should be 
made, but the difference in the modes are night-and-day.

When I spoke of "practical" I was referencing the amount of money, 
equipment and effort put forth vs. the quantity and usefulness of spots. 
Any beaconing mode has some chance of being copied. For a QRP beacon, my 
money is on WSPR.
