that radio's gonna be cake to solder. you're gonna scream at teardown/rebuild, but the actual solderhackin' will be ez. next harbor freight trip pick up a magnetic dish for screws  the vol pot might be hinky cause it may have five pins soldered through, aint nothin i cant deal with. try lifting pin 7 on a surface mount DIP to pull a serial line out of an Icom PCR100. that's tricky.

weller should be good, i'm bringing my trusty rat shack 40 watt too when we fix it up. it's trash, but i'm skilled enough now that I can solder AWG 12 outside in a breeze with it or lay down pcb joints

what you do is: first use deoxit on the pot. that gets it nice and squeaky clean and washes away all the nasty lubricant in there. then you use faderlube, which puts it back

i caused a pileup today on 6m lmao i usually leave the radio on 50.125 with the DSP NR cranked, its not intelligible but it will give the squawks I need to perk up the ears had the beams swung southwest as tx/florida was open and i thought it might move west (and i dont care about florida/tx) heard a cali dude calling, threw back to him, signed with him and the frequency loving EXPLODED i worked 26 dudes in 30 minutes from arizona, vegas, cali, oregon lmfao and they all said i was absolutely boomin in either 59 or 20 over. i think this new antenna is fuckin dope as helllll

I guess in my last post I let the cat out of the bag; I a geek, ham radio, who attends, anime, furry, science fiction , and comic-con conventions and dabbling in Steampunk. Some times I do bring my HT to check into the anything goes net on Friday or to amuse myself on a local repeater or simplex when things are slow. I am a furry , that is fan of anthropomorphic animals in art, literature, and cosplay. There a small but active group of ham radio operators who are furs and often meet at conventions. At last year Rainfurrest, a convention in the Northwest , the furry ham ran a ham radio panel and set up a demonstration station. You might of heard in the news how at Midwest Furfest some twit released chlorine gas hotel stairway. http://www.chicagotribune.com/news/local/breaking/chi-19-hospitalized-thousands-evacuated-in-gas-leak-at-rosemont-hotel-20141207-story.html What you might have not head how a few enterprising hams set up a impromptu net to keep everybody informed during the evacuation of the hotel. Then next day when things cleared , they sponsored an exam session welcoming few new hams and upgrades. While I do not think one need to buy a pair of ears, but not to discount a potential interest in not the usual places.

 dropped by grandpas house, he was in the middle of throwing out some useless old stuff LED numitron tube replacements, complete with tube sockets, internal current limiting and for some reason a moderately large tantalum over each series resistor which will make PWMing them a bit tricky these were used in older gas station pump meters for a while before they were upgraded to LCD also, just found out about this generic DSP addon: https://www.bhi-ltd.com/noise-cancelling/pcb-modules-low-level-audio/nedsp1061-kbd.html seems to be a voice recognition type DSP noise reducer addon for virtually any modern radio, been looking for something like this for ages so definitely gonna try one out in the 706, if it works well i'll get one for the TS-850 too

today I remembered that, as a lame technician, I still have Novice privileges and can use CW and data on 10m I also found what is probably the most useful thing I own, in a toolbox (someone recycled it):  with the universal RF adapter kit, a random wire, and the MFJ-971 and Ten-Tec Argonaut 509 that I picked up on Freecycle together, I might be on the air e: how is it I've been seeing photos of elecrafts around for months and i only just realized that the little thingy everyone has attached to the kx3 is a set of morse paddles and not, as I thought, some kind of weird clamp atomicthumbs fucked around with this message at 03:09 on Jul 23, 2015 |

little bit of column A, little bit of column B. people don't call CQ because the band is closed, so nobody knows when it's actually open. It's why I make it a point to scan http://www.qsl.net/wj5o/bcn.htm - and because of that I was able to be a new tech's first HF contact a few weeks back on 28.480 but we actually do have a super lovely solar cycle this time around and some pretty grim predictions are coming in. and its possible that we will not see a solar cycle like 19* or 22** for the next seven or eight cycles. so there is a nonzero chance that HF will suck for the rest of our lives. *19 is the bonkers solar cycle that gave everybody a decade of ham magic from 54-64, it's why all the old men always yell YOU CAN WORK THE WORLD WITH A WATT. yeah gramps you sure can if there's no digital devices in existence yet to clog up HF, and the ionosphere is so charged that Yuri Gagarin can light a cigarette by just holding it out the window on the way up **i got into ham radio at the peak of cycle 22. borrowed a 25 watt 10 meter radio and threw a speaker wire dipole up fifteen feet and would come home from school every day and work argentina and south africa and trinidad like it was a local phone call

oh hey, i picked up this nice communication receiver, came off a royal navy ship that was later blown up to test some missiles or something: 15k-30MHz, AM, SSB and CW, fully passive preselector on the input for excellent performance, frequency accuracy is quite good even after 5 years in storage unfortunately it was part of a kit  Elektrisk Bureau 500W PEP CW/RTTY/SSB (LSB only) with autotuner and several tuning memories includes 230V single phase and (if available) three phase power and came with three binders full of manuals, service details and schematics tested a few years ago, seemed to work then exciter, receiver and several panels are removed in that picture, somewhat modular design so i can use a small HF like the 706 as the exciter if i want to run USB unless the old one can be modified

I need to figure out if I set 'rf squelch' to say s5 and I'm scanning and the Tupelo repeater or whatever and it comes in at s2 (but with a pl tone) if my rig will ignore a) the squelch knob or b) the rf squelch menu setting. but I guess if I just ignore simplex and he FD in town I could turn the squelch way down anyway e Jonny 290 posted:when i'm on my mobile whip that is mounted right above the driver's door, i have s5-s7 noise across the 2m band. 144.000 has a full scale carrier. it quieted down a lot when I got out in the country though. idk.

for some reason PL tones are pretty uncommon in norwegian repeaters, my home group even set up a fusion repeater in hybrid mode without enabling subtones on the output freq (i ended up turning it on myself) if you have broadband noise then a real noise squelch should reject that pretty well, my icom HTs and the kirisun DMR both handle broadband noise very well with auto squelch

that's the garage of a friend of mine who's had it for years, he wanted to sell it but no one in the area was willing to put in the effort to reassemble it (even with the loving 1000 page assembly manual and all the parts right there). he offered it to me for free provided i actually take it with me, so i took the exciter, receiver and manual stack with me today he did a lot of different jobs before he retired so he has contacts all over the place we'll disassemble the rack on saturday and i'll drive it out to the vacation house where i have room and the loop antenna to run it (might need a new balun to run 500W though) real question is if it the 10A circuits in the 50 year old house can handle it, you can just about see the MASSIVE toroidal transformers near the bottom in the picture, it's fused for 10A

read through the manual a bit, and a) i can probably make an expansion board for the exciter to do USB by using two DDS boards and a microcontroller, there's even a spare card slot and it's entirely modular so it's just a matter of rewiring coaxes b) the ATU will be fun to set up it contains a number of giant inductors, including a huge loading coil for MF operation, the installation procedure is to run it manual, attempt to tune pretty much every band, then change taps on the coils to get it tuned on each band, write down the tuning settings from the front panel, then solder a strap-board up to "program" the tuner so it knows where to start the TS-850 is a bit easier to use IMO, but it can't exactly tune a 100 foot longwire to 512 kHz either there is not a single programmed part in the entire system (possible exception: receiver, which is a commercial unit), it's all 54 series logic and some more esoteric parts for the synths, ATU is done with straight logic and transistors antenna output seems to be some kind of busbar, which is a bit scary, there's also a redundant antenna output and an input for a redundant transmitter (with automatic primary disconnect when it detects power on the input) can't imagine what this system cost when new longview fucked around with this message at 22:30 on Jul 23, 2015 |
