6M AM is rare so you will need to work at it. All the more rewarding when you do get a contact. If you know CW that's a plus.
If the rig is not up to snuff on transmit, find the manual online and see if you can check it out. It is a simple rig and the TX section is very simple.
I am told the best height for a 6M beam is about 35 FT. I do not know if that goes for a regular dipole but i don't see why not. For AM, horizontal antennas are probably more in use. FM is usually using verticals. I only know 6M FM gear except for that i had a 99'er for a while. It was plenty sensitive on RX, but I was (am) between antennas. Of note it covers only to 52Mhz, I do not know why it does not cover to 54. But anyway.
For one thing, you might want to look at this beacon map and see if you can receive any of them. This will tell you how the band is and what direction it seems to favor..

http://ac6v.com/callfreq.htmthis in general has some good links. Try to join the (or an) 6 meter e-mail reflector.
http://www.ac6v.com/hambands.htm#50The antenna is everything with that low power rig, so put up the best one you can make or find. If you can make a simple beam, do it, so you will get some gain. A large size used beam is only $50 at a hamfest. If that is not possible, then a dipole is good. The nice thng about 6M is that the antenna is no bigger than a big TV antenna, so you can put it on top of a 35Ft push-up pole with a TV rtoator and guy the whole thing without spending alot of $. Don't be discouraged if you do not find contacts at first, I have some old buzzard's logbook showing hundreds of 6M AM QSOs (several per day) back in the 1950's and the guy was tunning only 10-50 watts..
That's all the advice I have on 6M.
About the topic views, like he said, most people here do HF, only a few are 2-turn folks or plumbers.
