If you get your shore stations also setup with PSK31, you'll have reliable
text comms from any point on the planet. I worked a Japanese station that was running a 20 meter dipole and 10 watts! PSK stations will raise hell with you if you hog the bandwidth with big powerful transmitters. It is simply amazing how far down in the noise the computer running this software can copy.....a station you can't even hear! As it's free.....give it a try! 73, and welcome back to ham radio DE Larry W4CSC Very cool! Will definitely check it out Any rigs your recommend buying to use the above? |

If yes that's very line of sight on a boat. Yes? Would pactor be a better choice for sail boat in middle of sea? If you are going to be sailing offshore, go take the easy 24 question test to get your Marine Radiotelephone Operators License. Then get a SSB that has the ham bands on it also. This way you can call the Coast Guard if you need to. Come to think of it I'm not sure if you even need a MROL if your vessel is volunteerly equipped (not carrying more than 6 passengers, under 300 tons, not a tug over 26ft. etc.) Your boat still has to have proper station license. |

ICOM advertises some of theirs as "ham band and e-mail capable" ICOM IC-M710 I'm not a ham but some people that post here are they might have some suggestions. I ve spent quite a bit of time at sea on tugs and wouldn,t want to be out there with out communication to the coast guard etc. |

That's correct. ICOM advertises some of theirs as "ham band and e-mail capable" ICOM IC-M710 It will do the ham bands, but email ready is really AD-hype. It means you can press a single button to get to your favorite email frequency. HF email doesn't generally work that way. The computer tunes the radio to the frequency you choose based upon propogation. I'm not a ham but some people that post here are they might have some suggestions.

Larry always goes on about PSK31 being better than PACTOR. Fact is that
they are apples and oranges. PSK31 is a very low speed interactive mode that is reliable in many cases. PACTOR is a high speed packet oriented mode suitable for email. If you are interested in email, PACTOR is the only real choice right now. If you want to just converse with others by typing on the keyboard then PSK31 is a good choice. There is no equivalence between the two.

The worldwide homepage of PSK31 is: http://www.aintel.bi.ehu.es/psk31.html PSK31 only requires your transmitter to be in the 10-20 watt output class because it will copy perfect text....right down so far in the noise you can't even hear the guy you are communicating with. Wanna hear it? That's easy. Tune any USB receiver to 14.070 Mhz, the "PSK-band" on 20 meters. You'll hear this funny "warbling" sound, many of them at once. On this website: http://www.qsl.net/wm2u/psk31.html You'll find pointers to all the different PSK31 programs to run on your computer....any Windoze computer will do.....like your boat notebook. PSK31 uses your computer's sound card and does all its stuff in software....no external "boxes" are necessary. I, personally, have always used WinWarbler: http://www.qsl.net/winwarbler/ but most hams are using Digipan: http://www.digipan.net/ Any of the programs work great. There's even versions for Linux and Mac. Winwarbler will copy three separate stations SIMULTANEOUSLY, and you can switch your transmit back to them with just a mouseclick.

Larry,
How do I send an email to my non ham daughter in Orlando from 100 miles north of the BVI with PSK31? krj Larry W4CSC wrote: wrote in : I want to get back into some form of free ham radio comms that would allow me to stay in touch with people while living in an RV or boat The boaters have been sucked into the most overpriced, proprietary-of- course, digital mode, Pactor.

Be very careful of ever listening to Larry...he is often a technical
idiot...but not always. So listen to him only when you well understand the turf...he has a gem once in a while but not for the newby. PSK is a toy mode for rag chewing. It is nice. I use it and recommend it. But it is not for any even semi-serious conversation. It is a different version of operating AM on the long wave bands. Fine for hobbyist but not really practical. Good CW for the Morse defective. Serious boat stuff is done in PACTOR for email and similar or good old SSB for position stuff or various nets. The email systems are actually pretty sophisticated and involve a lot more than Pactor. But Pactor is pretty well required. Ideally one goes with some combo like an ICOM 710 and 706. The 710 is an SSB receiver that will work on the ham bands while the 706 is an amateur radio that will work on the marine HF bands. Non-emergency use of the 706 on marine bands is illegal but works quite well. I would however consider it an emergency any time I needed to work on marine HF and did not have a legal marine radio available. YMMV. Jim Donohue KO6MH wrote in message ...

solar power is inefficient, generators are noisy, wind generators are
expensive.. Plus, when you key down on 1000 watts what type of antenna are you going to be using? A yagi on your mast? Weird! "Wayne.B" wrote in message ...
