fuckin ebay. i received both my antennas but not my baofeng or my pigtail for my sdr.
|
# ? Mar 13, 2014 10:38 |

so i had the uni pd and local SD up on the baofeng coming back from dropping kid off @ daycare. i hear a blurblurblurblurblurblurblurblurblurblurblurblur like deffo trbo/dmr on the sd station. i came around the corner & there was a local cop hiding in a construction zone. was he talkin on local pd freq and overpowering my radio or was smth else going on? i know the lil click thing whne i drive in certain spots is the radio bein overpowered, but would the overpowering signal come in loud and clear on a diff freq?
|
# ? Mar 13, 2014 15:33 |
|
yes, very possible. the big downside of SDR based radios like the baofengs is that they have minimal if any filtering on the front end. the big 3 radios don't get eaten up nearly as much (though some of them still have problems) basically the more 'wideband' or flexible a radio is, the more its gonna get swamped with intermod and phantom signals. this is why i keep 100 lbs of 80s icom on my bench, they don't give a gently caress about anything they're not tuned to

# ? Mar 13, 2014 15:45 |

yeah the front ends on those boafeng HTs aren't the best in the world so if he was running like 50 watts from his mobile rig you could be getting crosstalk from his radio edit: beaten by johnny, of course

thats cool, im starting to realize im quickly outgrowing this lil guy. i mean it owns for what it is but ya i gotta convince the wife i need a better radio. i just scanned a bunch of documents offering to sign my life away if they'll accept my price, so probably not in the cards until maybe xmas or some poo poo unless i come across a screamin' deal-- i also have no idea what i want/need. that ic-7000 sure looks nice but i bet there's something long forgotten in someone's garage/shed w/ my name on it.

7000 is nice but a little upmarket, it has IF-based (not audio) DSP so it is a few more bucks. its daddy, the icom 706, has more conventional filtering (no big deal for entry level) and you can't swing a dead cat at a hamfest without hitting a 706 for sale. everybody has one. (it's shameful that i don't but i'm not in radio buying mode) all of the 706's do 100w on HF. original has 10w on 2m, the MKII has 20w on 2m and the MKIIG has 50w on 2 meters and adds 70cm (20w). i'd probably say that a mkii would be around 450, 500 bucks. or if you make hamfriends over the summer i bet you can find an old man with too many radios who will sell you his 706 for 400 bucks. turn on the struggling young father charm and old hams will throw gear at you for cheap

Yeah you can do just about anything with a 706 that you can do with a 7000 as far as casual operation goes. plus the 7000 has been discontinued so every OF with one will want a premium for theirs. (Can't buy this no more!!) if you know you just want to mess around on HF for awhile you could find a old radio like what Johnny has (IC-735) for around $250-300. I used to have an IC-735 and they are more or less indestructible unless REALLY abused (mine literally fell out of a truck and was fine). sort of wish i didn't sell it but when we bought our house I sold off a bunch of redundant stuff for extra money now that we bought our house as long as i'm selling off things now and then and not hoarding radios my wife is usually okay with me buying crap. before we bought the house though we never bought anything so i get where you're coming from putty

eh 750 for the K2 kit. not cheap but not shocked at the price either i think they come with the hairy poo poo like the CPU pre-soldered, and maybe the inductors are prewound too still you need $2k of test equipment to align the fuckin thing i believe sniep: hahaha i thought somethign looked off

The K3 is expensive but a K2 is a lot less ($800 I think). Only hitch is you literally have to solder everything together on a K2.

here's some pdfs describing the apollo missions S-band radio system http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19660018739.pdf http://www.hq.nasa.gov/alsj/19650010806_1965010806.pdf from wikipedia: quote:Allocating uplink/downlink frequency pairs in a fixed ratio of 221/240 permitted the use of coherent transponders on the spacecraft. The spacecraft tracked the uplink carrier with a phase locked loop and, with a series of frequency dividers and multipliers, multiplied the uplink carrier frequency by the ratio 240/221 to produce its own downlink carrier signal. and a retelling of how the parkes receiver station got the actual OTA signals of the first steps http://www.parkes.atnf.csiro.au/news_events/apollo11/pasa/on_eagles_wings.pdf

longview posted:here's some pdfs describing the apollo missions S-band radio system holy poo poo this is great some of the tech deetz are amazing given their 1966 context quote:This diplexer provides approximately 190 db of isolation between the transmit and received frequencies. quote:The power amplifier utilized in the USB System is a 20 kilowatt CW klystron amplifier. This power amplifier has sufficient bandwidth to amplify simultaneously the LEM's uplink carrier and the CML uplink carrier. This is required at a dual 30' station. A dual 85-foot station has two (2) complete transmitters in order to provide more gain during those mission phases when it is necessary to have more uplink signal power. quote:The two (2) transmitted uplink frequencies are very stable, being derived from a time standard having a stability of approximately 5 parts in 10" . and then: quote:In addition to teletype, high-speed (2400 bps) circuits will be available into and out of most of the sites

Anyone do MW DXing? I used to dabble a little bit with a Sony 7600GR, just using the internal bar and a select-a-tenna. Never got anything too fancy, two or three 1500+ km stations. I've since moved and my reception seems to have gone all to hell even though I'm less than a mile from where I used to be. My old place was a little bit higher elevation than where I am now, but I figure that shouldn't matter for MW. Other than moving as far away from RF sources as I can, does anyone have any suggestions as to what might have changed or what I can do to improve matters?

Yeah, AM broadcast DX was my introduction to the hobby. I still tune into 850 KOA Denver and 780 WBBM Chicago now and then If you think it's localized noise, grab a portable AM radio (yeah i know, not exactly in everybody's junk drawer any more) and go hunting. You might find a lovely fluoro light or something somewhere. Other than that my only other suggestions would be go investigate active antennas, mounted as high and far away from crap as you can. the mini-whip we've been bouncing around here that longview built should be pretty perfect - guys use them all the way down to LW.
