    Big switching power supplies - what's the forum favorite?

    I have an R810 and am going to be adding an R740 to the main rack at some point. Roughly 20 years ago I put together a server cluster for security operations at a previous employer in roughly the same size room as my downstairs office/radio shack. Two full size racks. One had several Dell...

    Big switching power supplies - what's the forum favorite?

    Any special concerns with stacking, or just simply parallel the outputs?

    Icom 718 issues after static hit

    Slightly off-topic but 718 related nonetheless: Has anyone experienced a front-panel lockup with one? I have a 2nd run Gen 1 (S/N 2xxxxxx) 718 which - when in use - will occasionally have its front panel become unresponsive. Sometimes it happens when the radio is just sitting in RX; other...

    Big switching power supplies - what's the forum favorite?

    Putting my new operating position together. Currently have 3 Astron 50A linear supplies, each driving 8012 Rig Runners (or with their companion transceivers wired directly to the supply terminals). Need an option for the VHF/UHF bench. There are a few brick type amplifiers (CPI HF150...

    Replacement bulb for remote vfo

    Came to post this. I have more 7 line stuff than I care to think about and am going to be replacing a lot of lamps when getting that gear back into the lineup.

    HR2510 Audio limiter location for restoration

    Neat old rigs. I ran an HR-2510 or HR-2600 on my 10M packet node for years. The radios often saw 12+ hours continuous use and never broke a sweat. Few years ago I got an original Lincoln and an HTX-100 (a kissing cousin) and all will eventually go in a rack on my vintage bench. There is a...

    Do you live in an Urban, Rural or Backwoods area??

    Used to live in a smallish suburban city. Now live in the middle of farms and ag. Called the zoning director before we bought the place, asked about antenna towers and he said as long as yours doesn't get into FAA territory or fall on a neighboring house, they don't care what I put up. I can...

    CPI CP2000 issue can use help

    I have a couple CP2000s in my stash. One definitely is in need of recapping. They're both going to get it done as soon as my bench is back up and running. Love that radio. My late friend Hank had one and I was very impressed with it when we had it on the air.

    Oldies but Goodies

    Have a bunch of Royce stuff - 624, 625, 641 and 642 plus a couple 639 mobiles. Those are among my favorite mobile rigs. 2ea Pro-40/SPK-40 and one SOC-40. Would love to find an OSC-40 and SWR-40 for it. 2ea CP-2000/BC-2000 - one was bought from a member here and restored. 1 CP-400. I have every...

    POTA haters and purposeful interference.

    What's the story with 26.715? I hear a lot more Bowl-style activity on that frequency than I do on Ch9. Wish I'd have stayed with a Spanish speaking gal pal long enough for her to teach me more of the language - including some of the cultural nuances.

    POTA haters and purposeful interference.

    I learned a lot about weak-signal upper HF work (optimizing antennas, sked times, etc) when skip rolled up for the evening and all the locals went to bed. Had a number of friends on channels 35-40 and we'd keep in touch in the wee hours of the morning, sometimes with no movement of the S meter...

    If you've owned an Icom rig has it ever had to be repaired?

    Yes, with caveats: Have a number of R-71As, R-7000s, a couple each IC-751As/R-70s, an IC-745 and 3 IC-720As plus the amps, auto-tuners, etc. Some were bought broken and restored. Others...the trimmer capacitors in the PLL sections of these rigs are known problems and have either been replaced...

    POTA haters and purposeful interference.

    Last one I remember with an actual REACT booth was south of Canton, OH and was periodically active through the mid-2000s. Me and a lot of my motorcycle buddies (many of whom are licensed hams, CBers, etc.) would stop there for coffee on the way home from a day's ride. Always put a bit of lettuce...

    Kenwood SM-220 Station Monitor

    Funny thing running across this post. Sitting immediately next to me on the bookshelf is a connection cable for the two-tone Out to 4 pin Mic In function. Probably meant for use with a TS-820S as the SM-220 was released about that time. I have a few of the things. All but one have BS-8...

    Chipswitch for 2510/2600/Lincoln

    Will the Chipswitch also work in the original Lincoln (not Lincoln II)? I bought a couple of the chips years ago for my HR2510/2600 but never got around to installing them. As a previous poster noted: They're a simple radio - but I like them. Managed to collect the entire series...

    How many radios do you run?

    Thread bump (and I haven't been on here for a while anyway): On CB - Either a CPI CP-2000/BC-2000, Pro-40 or TRS Challenger 1200/1400. Rotate them in and out from time to time. Scanning/monitoring: Probably 30 different receivers running concurrently, all PC controlled. Multiples of Optocom...

    uniden washington blead over.... :(

    How are the electrolytics going to affect adjacent channel rejection? This is clearly an IF filter problem. More to the point, leakage around an already marginal filter.

    Riff raff on 38 LSB

    Once upon a time I used to love hanging around Ch36-40 - you could always find a group of SSBers in that area, even when there was no skip to speak of. Yes, that "day after day" shtick gets real old, real fast. Maybe the Class D service will get popular again and people will start...
