i have a bunch of rtlsdr gear kicking around here from a project last year, think i'll get it set back up after this cool thread

there wasn't a whole lot to listen to last time i checked the uk airwaves. just air traffic control and watching plane transponders. ships never worked here for some reasons, i blame the terrible software

buy an upconverter, check out the HF side. there's lots of SSB there so SDR is nice, and plenty ham/digital/whatever stuff to tune in.

I really really hate tuning SSB with SDR software, maybe I should buy one of those glowy hockey puck things

http://utaharc.org/rptr/synchronous_62.html this is one of the cooler repeater projects I've seen, two repeaters at two sites on the same frequency, with a very slight frequency offset and a duplex link + voting circuit they implemented a repeater system with diversity receive and transmit to normal radios

this is the HT antenna that i use on my FT-60R



Is that a Smiley? I had a Smiley tri-band which I think they later renamed to dual-band because it was bad at 222mhz or w/e, but it went missing somewhere :(

i know its been said that rc planes and ham isnt a good mix, but is that more a control issue? what if a normal rc radio was used for flying and the ham radio was used for telemetry/video/other comms but no actual stick and rudder controls?

so this is only tangentally related but how hard is it to wire up a second batt (marine deep cycle) so that i can run a radio or other accessories (either separately from vehicle electronics like cd player or w/ them?) im assuming u can't/shouldn't crank off of a deep cycle batt but i want the alternator to charge it at least obvs. on the suburban apparently batt install itself is super ez cause theres a factory location for second batt so im not worried about that aspect. would i be better off letting my shadetree mechanic guy do this when he fixes my AC compressor?

window shopping - an Icom R9000 receiver has gone on ebay, it is not the best receiver ever made, but it is up there, and I have wanted to own one for twenty years.

cool thing about this listing is that the seller obviously knows this radio inside and out http://www.ebay.com/itm/Icom-IC-R90...S:B:SHOP:US:101

"wahh everythings going digital" so what? go digital.

ISS is going to fire up a DTV transmitter and if you're set up for it you'll be able to get high res video from it:

quote:

Ham Video Commissioning now scheduled

The Ham Video transmitter, which is stored in the Columbus module of
the International Space Station, will be installed March 6, 2014. The
transmitter will be powered on briefly, just the time needed to check
that the connection cables to the antenna, to the power supply and to
the camera are installed properly. All control LEDs nominal, the
transmitter will be considered ready for Commissioning and will be
unpowered.

The first Commissioning step is planned March 8. Michael S. Hopkins
KF5LJG will power on the Ham Video transmitter in configuration 1:
ARISS antenna 41 Frequency 2.422 GHz Symbol rate 1.3 Ms/s The
transmission will start shortly before the pass of the ISS over the
Matera ground station in south Italy at approximately 13.29 UTC.

The ground station will stream the video over the BATC server
http://www.batc.tv/ .Please select Member Streams and ISS.
During the pass, different configurations will be tested with ARISS
antenna 41.

After the pass, the Ham Video transmitter will stay powered on in
configuration 1 till the following Commissioning step, which is
planned Sunday March 9, 2014 at approximately 12.40 UTC.

For about 24 hours, the DATV signal will be transmitted permanently,
but the camera will be powered off. The reason is, that the camera is
battery powered and no provisions are made for frequent battery
replacement. This mode is called "blank" transmission.

During Commissioning step 2, different configurations will again be
tested, this time with ARISS antenna 43. The Matera ground station
will stream the video over the BATC server.

Possibly, blank transmissions will occur in the period between
Commissioning step 2 and the following step, which is not yet
planned.
We will circulate Ham TV Bulletins to inform on blank transmissions.

Reports on reception of blank transmissions are very welcome.
Reports can be filed via this webpage:
http://www.spaceflightsoftware.com/ARISS_FSTV/submit.php
http://www.spaceflightsoftware.com/ARISS_FSTV/submit.php
Participants using the Tutioune receiving software, developed by
Jean Pierre Courjaud F6DZP, can record as well as stream detailed
parameters of the received signal. Please see:
http://www.vivadatv.org/ http://www.vivadatv.org/
Thank you for your participation

Honestly i'm not sure and I didn't know hams were tinkering with DTV (we have a long long history of analog TV operation, there are even repeaters)

intrigued now, good thing to study for an icy sunday where I CAN'T GO OUT AND PLAY WITH THE NEW ANTENNA I BUILT YESTERDAY

when I read up on them I noticed that most western nations have stopped using them in the last decade, but the russians and other east block countries seem to still operate them

presumably the more technologically sophisticated spy agencies have switched to horse ebook twitters and other more advanced communication methods, which makes sense since these days having short wave radios is pretty rare compared to 30 years ago

what is the legality of using 433mhz bands (e: in the us)? theres a ton of dirt cheap parts on DX that work with microcontrollers. they seem like they've have very low power but if it will piss off some greybeard in my town then i either wont do that or will do it even harder and smuggier than before

the 433mhz subband is also an allocation and these things are 100% legal. actually almost all of the 70cm band is secondary allocation, iirc. maybe its just big chunks of it, forget for sure
