Not quite directly relevant, but I just had to replace a Netgear GS-308 UNmanaged switch with a GS-108 unmanaged switch, using the supplied wall-wart. No discernible noise from it - now if my power
Fortunately, that line noise is only present intermittently, and I powered down the switch while listening on a quiet band without line noise, so I'm pretty comfortable saying that it's quiet. 73, Pe
This was very interesting - the TinySA Ultra sounds like a great tool. Checking online, I was surprised to find it for sale for as little as $70 (Karagas), and as much as $140 (Rbay). In this era of
This morning I got up and went on the air in the CQWW RTTY Contest. Everything had been fine yesterday, but as soon as I made my first transmission, both of my monitors shut down. Eventually, I fou
I wish I could tell you I found a "loose" PL-259, Frank - I think the most I took up on any of them was about a sixteenth of a turn. Fortunately, at 100 watts, carnage was nil. I have a hunch that
Sorry, not what I meant. The worst one was 1/16 of a turn from where they wound up when plier-tight. That is, it *was* hand-tight 73, Pete N4ZR A PL-259 backed 1/16th of a turn from fully hand tigh
Just to be clear - before this, I have had zero problems from hand-tight PL-259 connectors, going back as far as I can remember (50+ years). That's why this instance struck me as so remarkable. I've
Sounds like AT&T knows it has a problem with responsiveness, to have set up such an intervention mechanism. Good to see. 73, Pete N4ZR It is a bit intimidating to think that resolution of similar RF
at 0114Z, a signal suddenly appeared in the FT8 segment of 30M, every 50 Hz from top to bottom. As I write this it's still there. I presume another radar? -- 73, Pete N4ZR _________________________
Thanks, Don and Jim for the confirmation - glad it's gone, though it's interesting that FT8 continued to work through it. I had the same thought about the 50-Hz spacing. 73, Pete N4ZR Looking at the
Corcom datasheets for at least some models give insertion loss versus frequency values for both modes, common mode and differential. I'd be awfully surprised if they weren't compliant with the cap r
Jim, your report reminded me of the strangest RFI I have seen - a heated dog dish next door that totally took out 160M on my shunt fed tower a couple of hundred feet away 73, Pete N4ZR On 11/2/2023 1
I send a few characters of CW into my Carolina Windom on 40M and after a delay (1-5 seconds after I stop sending) the K3 flashes a HI CUR warning, and the audio gain is reduced significantly. Touch
Amazing - these people ought to be in jail. I'd love to take one apart - I suspect a small transformer, a diode rectifier, a resistor and an LED. 73, Pete N4ZR https://consumerbags.com/review/powers
Interestingly, I just tested the shielding on a USB A to USB C cable I have, which looked like it should be fine, with a transparent jacket over woven shielding and a big ferrite bead - about 1 meter
Oh Joy - another thing to check. I'm using a plain Ethernet Cat 5 patch cable from my amp to my computer. Judging by how floppy it is, I suspect no shielding at all - but a question - if there were
Not on mine, Jeff - all plastic. 73, Pete N4ZR Oh Joy - another thing to check. I'm using a plain Ethernet Cat 5 patch cable from my amp to my computer. Judging by how floppy it is, I suspect no sh
I have about 8 USB cables in my station, two going directly to my computer and 6 to a hub. I suspect some RFI because periodically- every couple of hours - a couple of USB devices - keyboard, mouse,
I hope this person has been banned from the reflector. Happily, a lookup of his name on QRZ found no callsign. 73, Pete N4ZR Sent from Yahoo Mail for iPhone I have a WD8DSB Loop that I use as a nois
Yes, indeed - radio, 2 keyboards (one wired, one wireless), amp, mouse, Winkeyer, SDR, two USB backup drives, and maybe some more. 73, Pete N4ZR I'm using all the USB ports on my T540 and docking sta
