Not being told they are not welcome if they don't have the equipment others have.

The discussion centers on the importance of best practices being taught and demonstrated by those elmers you mention. Elmers walk with you, guiding, correcting, encouraging along the way. The need to have practical knowledge, and all too often we see people who don't operate, or just started themselves, passing out poor or erroneous information. If the shields can be dropped for long enough, there are lots of elmers right here on this list to help the newbies out. Elmers should continue to learn as well.

> By the way check the prices an arrow >antenna that will give someone the best chance to get into AO-85 with a Cheap Chinese radio is about $150.00.

Elmer moment right here: The arrow without the diplexer is $60 cheaper than the one with the diplexer (http://store.amsat.org/catalog/index.php?cPath=1). Use that $60 for a 2nd receiver and now you can hear if you are getting into AO-85 or SO-50, adjust for Doppler on AO-85, and make more contacts, and cause less QRM. You'll need a set of headphones as well, about $5 at Big Lots or Walmart. Better experience for you, better for everyone else, less money.

Or, build the functionally same antenna for $10 and a few hours time, and save some more bucks. I love my Arrow(s), but a WA5VJB or IOio antenna works just as well. Links to plans can be found here: http://www.amsat.org/?page_id=2144
