got me tech license. Maybe should have studied for / done the general too. The testing area had both a Krystal and a White castle less than a mile away from it it was amazing

I have an RTL SDR and I live in a tiny apartment with windows only in one direction. I would like to be able to receive airband but the included antenna doesn't seem up to the task. Is it possible to get a worthwhile signal without an antenna outside? What kind of antenna would you recommend (preferably one I can build easily with very basic supplies)?

What kind of antenna would you recommend (preferably one I can build easily with very basic supplies)? you won't have room for anything much larger than a half-wave dipole in a window, that's what most airports seem to use anyway. I'd design it for around 120-130 MHz. I wouldn't try tuning it, air band is one of those serious business bands where even owning transmitters tends to be illegal any more gain in an omni antenna and they become extremely tall, or you have to build a yagi 2-3 element yagi could play, just add a reflector to the dipole afterwards and check the RX gain setting on the dongle first

http://forums.qrz.com/showthread.php?445092-Amateur-Radio-Superstation-K3LRham posted:I recently had an opportunity to visit the station of Tim Duffy, K3LR of West Middlesex, PA. Tim has been a ham since 1972 and in 1987 he bought an 11 acre, 1860's farm property and immediately started setting up his dream station. Today, 27 years later, it has become that and much more. Simply stated, the K3LR station is one of the number one Multi/Multi contest DX stations on the planet. Tim engineered and built the entire station and its massive 11 acre antenna farm of 13 towers, including its Yagi's, directional arrays, and switching systems that give it capabilities that are seldom seen in the amateur world.

i like ham radio when its making contact across the globe with an antenna hastily made with cheap speaker wire and PVC pipe versus perfectly calculated multi thousand doller setups.

Yep, that's the poo poo right there. Speaking of which, I'm going to finish some radio wiring this week and should be on the air by the weekend. The HF antenna got wanged on a tree when I was backing out so I gotta straighten one section, but other than that ive got all the really important gear.

spankmeister posted:jonny what would i need to talk to you from across the globe? a shortwave (HF) transciever, the right antenna and the right conditions Best bet would actually probably be a digital mode on the 20 or 30 meter band. You can get out pretty far without needing shitloads of power.

can't hit the drat 440 repeater w/ my uv5r anymore. maybe it's the new QTH but it's def annoying. someone was able to listen in reverse or w/e and copy my checkin but ugh. I'm just a few miles from the repeater.

I had half a chance to go work for Echostar in Englewood a couple years back and although the adventure would be cool I'm glad it didn't happen because I checked glassdoor and gently caress. Living in Denver was really tempting tho.
