Any ham radio opertaors here?
I have a general class ham license but have been out of
it a LONG time 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 So.... I want something small and compact. And Im not sure what "mode" of communications I want. I may want some form of digital comms like packet or pactor.... not sure Any advice on all this? What to get equip wise? What modes to get into? |
I would go to your local HAM store and talk to them about gear. There
are a lot of choices out there from tiny mobile QRP type rigs to larger base stations that will all work in your boat or RV. I would start out by getting a rig setup that's capable of doing packet and then adding a pactor or similar into the mix later. -Todd |

by getting a rig setup that's capable of doing packet and then adding a pactor or similar into the mix later. Packet is 2M only, correct? 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? |

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. 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.

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.

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 ...

The trade offs are as follows" HAM Must have a General Class license. Must have a radio that will do the ham bands. email is free, but absolutely no commercial traffic. Marine SSB Must have a marine SSB rig. Musr have a Ships Station License for the rig. Must have a Restricted Radiotelephone Operators Permit for yourself. Sailmail is $250/yr but you can do commercial traffic. I went with both. An ICOM-M710 enabled for the ham bands. And I had both Winlink (ham email) and Sailmail.

: Larry, How do I send an email to my non ham daughter in Orlando from 100 miles north of the BVI with PSK31? krj I've forwarded messages via email (for free, not $250/year) for people I've met on PSK31 (and other modes for that matter). All you need do is find a ham friend ashore who has internet service. You text up the messages to your daughter and send them to your scheduled ham ashore via any mode you like, PSK31 included, then they simply cut and paste the message into an email to your daughter, saving your replies to send back to you as 3rd party traffic next time you have a sked with them. OF course, this means you must have FRIENDS, not Sailmail business acquaintenances for pay. Some boaters (including ones listed here) are too damned independent for FRIENDS. You've met them, I'm sure. If you need business comms, ham radio isn't the place, of course. That hasn't changed..... CRAZY Larry also likes the idea of all ham-radio-equipped boats constantly transmitting their current position and data on another ham radio system called APRS, invented by Bob Bruninga at the Naval Academy so they could track lost cadets in Academy boats. Your daughter could just go to your personal webpage for your callsign at: http://www.findu.com/ From your very recent position report, she'd be relieved to see: A - Your still afloat, have power, are "there" and have been recently heard by an APRS reporting station in the network. B - Haven't declared an emergency. This, alone, would be very comforting, wouldn't it? She doesn't have to be a ham to look at the webpage, only you do. Just leave APRS running on the unused HF SSB rig with its packet modem when you're not using it. Silly me..... |

"thuss" wrote in message oups.com... HF transmitters are very common on boats and only draw a lot of power when transmitting and even then it's not enough to noticably discharge a normal house battery bank. True on voice SSB. Digital modes pretty much are like AM. They draw max power the entire time the transmitter is keyed. Last time we sailed from California to Hawaii we used the HAM/SSB nightly to talk on the PacSea net, Not much power since SSB draws power on the peaks only. get weather fax, RX for fax is pretty low power anyway. and do phone patches. Same as any voice mode. Low overall power. Even with our lowly 12V 450amp house battery bank I never really noticed needing to recharge more frequently than every third day, which is about how often I would charge the batteries when sitting at anchor. Sounds about right. Even using the digital modes, the amount of time one is on the air is pretty small. Unless one is ragchewing for hours on end a marine SSB or ham on board is not a heavy hitter. -Todd -- http://boatblogger/page/thuss http://www.marinewireless.us Falky foo wrote: Problem is powering a HF transmitter with enough wattage without draining your batteries. wrote in message ...

It'll run 6200V at around 950ma at full power. My math is a little fuzzy. That's about a kilowatt, isn't it? The pole pig hooked up backwards for the plate supply is quite noisy at this level. I took a piece of melted RG-8A/U about a foot long to a ham club meeting. It doesn't melt RG-17. All in good fun....back in the 60's a whole bunch of us kept building the monster 4-1000 linears because the tubes/sockets/chimneys were free. When 10 meters was as dead as a doorknob, before 2 meter repeaters, we used to fire them up into the Mosley beams and sit around chewing the rag late at night across town (Sumter, SC, pop about 25000). There was no low-end VHF TV to worry about tearing up. One night in the dead band we had a breaker from Perth, Australia, the only other person we heard across the band. He claimed we were all echoing like mad and 20 over S9. He had a little echo, himself, at 250 watts. We had a great time working him and the hams he'd called locally after first working us. The band wasn't dead, after all, just abandoned. By the way, in SC we have an unwritten ham radio rule. IF there's some kind of official or unofficial net, net control stations are never allowed to run enough power to actually hear them without straining. I never figured that out but it's been that way since I came here as WB4THE back in the mid 60's. Go figure.... |

Absolutely! I know that Winlink has stopped supporting PACTOR I and I
suspect that Sailmail has too or will soon. PACTOR I is 100 bits per second. PACTOR-II is 200 bits per second. PACTOR III can go much higher and is adaptive. I generally connectd at around 3400 BPS but it can go a bit higher with a really good signal. Doug wrote in message ... Proprietary inasmuch as only SCS makes TNCs for it.

I was under the impression that pactor II or III were far more reliable and allowed faster transmission rates thank PSK31, is that incorrect?

FCC TAKES A REALLY DIM VIEW WHEN IT HEARS AUDIO IN THE BACKGROUND OF ANY DIGITAL MODE because whenever the transmitter is on, it's transmitting that TV behind you on SSB while your digital tones are also on the air! Some radios with "data inputs" for the tones DON'T disconnect the microphone audio just because you plugged something into it. Test yours carefully. be sure then to unplug other hardware when using voice or you'll possibly have a problem with rf feedback somewhere. Oftentimes on voice nets I'll be working a maritime mobile and ask him about the rf in his audio only to have it clera up when the op unplugs his tnc. On another note, have been listening around the psk part of some band or other with a friend and heard the usual noises windows makes being transmitted. AS these are usually wider bandwidth audio they're verbotten in those sub-bands. Be aware of the sounds your computer makes in just normal operation and be sure not to transmit anything but what you really intend to. 73 Richard Webb, amateur radio callsign nf5b active on the Maritime Mobile service network, 14.300 mhz REplace anything before the @ symbol with elspider for real email -- They can have my command prompt when they pry it from my cold dead fingers |
