PuTTY riot posted:need 2 get my hands on a HF rig but I don't have time or money to I'm thinking of selling my all-bands rig because my lot is too small and antennas are expensive... But it was given to me by a really good friend so I may just ask if he wants it back. I'd love a handheld that could do HF but I think antennas would gently caress you over. There is a mobile-sized unit that can do 10/20m IIRC but I forget the name, I know someone in the other radio thread has one.

Jonny 290 posted:its pretty height dependent for sure. generally the beardos recommend 4:1 for low ones, under 10M height above ground or so, maybe go up to a 6:1 if it's higher than that. Def 4:1 in your situation though, which is fortunately really easily DIYable (i had a homebrew ocfd back in Arkansas that I enjoyed a great deal, balun was made of pvc and speaker wire) could you talk a little about how you made the balun? i have an "ugly balun" for my dipole at home, just wound the coax tightly around an old yogurt tub, but i don't really have any measurement devices so who knows what it's actually doing

i was looking at the broadband-hamnet thing and eventually led myself to this article: http://www.broadband-hamnet.org/images/stories/DataEncryptionIsLegal.pdf any thoughts on that? i've long held that restricting encryption makes networking over ham frequencies kind of hard because 1) can't use it for normal wifi stuff because of WPA + the prevalence of https, 2) gently caress if i'm running telnet to log in to a machine

Jonny 290 posted:been ruminating on broadbandhamnet + packet all morning Fidonet worked on a similar-ish principle, right? Aggregate all the traffic that needs to leave the town, then dial up an upstream guy and send it all in a batch, he batches messages that need to go further upstream and messages that go back downstream to other local nodes. Fidonet did it because long-distance phone calls were expensive; our motivation is that long-distance connections are "expensive" in routing terms, luckily not monetary terms. what i'd like to see is some way to associate a public/private keypair with your callsign. that way you would send signed messages within a worldwide ham net and people could actually verify that you were the one who sent it, not some dick using your callsign. if the FCC would let you put a key signature in the ULS that would probably be sufficient

i'm moving to albuquerque soon and when i get there i'll probably buy an old pickup before long, and then i'll just wire the kenwood directly to the battery (well, directly via a fuse) so it'll always get that sweet trickle of juice that keeps the memory alive even when the radio is turned off.

movers brought my poo poo today, time to see how lovely the 2m scene is and whether or not I can hang a dipole in my back yard without breaking my neck. there's a couple big conifers back there with no branches for like 30' so that could work as for insulators, is it ok to use the plastic electric fence insulators you'd get at a farm supply store? like this  hell, i should just buy some of those and a bunch of fencing wire, make a "shepherd's dipole" and submit it to whatever the new zealand equivalent of the arrl is.

i have a 10m dipole that i built back in CA, with a lovely "ugly balun", and i guess I'll try to rig that up, but what other antennas should i look at building for my back yard? it's pretty big, probably about 40'x40', with some trees at the SE, NE, and NW corners. House is along the south side, split-level so the east half of the house is 2 stories. edit: i have an all-band hf rig

I figure if it's not enough I can rip it open and take out one of the conductors and combine them, then cut it down to size. Rather than ruin your UHF cable, I'd recommend buying a 100ft spool of wire like http://www.amazon.com/gp/aw/d/B00FG...qI4L&ref=plSrch

anyone interested in playing with hf packet radio, specifically UUCP over AX.25 to transfer files, email, and newsgroups? i'm working out how to set up a soundcard tnc + linux AX.25 + Taylor UUCP + INN news daemon, but at some point I'm going to need someone on the other end to test things. why do this instead of the more traditional ham options? for starters, traditional ham software is basically a dumpster fire. with this, you can communicate in public newsgroups or "private" mail, and copy files to each other if you want, using regular unix programs that are actually documented. uucp over packet radio is also something that used to be reasonably common back in the day, and should still work quite well because uucp was originally designed for lovely slow links (including 300 baud modems and 300 baud packet radio). it eliminates the overhead of tcp/ip and instead should be able to just run uucp's own simple protocol over the ax.25 link-level protocol.
