AMSAT: RFI from LED bulbs?

by Robert Bruninga

I am hearing reports of RFI from these LED bulbs. Not just HF, but also VHF. If you can make any quantitative assessments of such RFI, please let me know. And the amazing thing is that at VHF you will never notice it because RFI is noise power and it is noise power that keeps a squelch CLOSED. Manuallly open the squelch and sometimes RFI will show full scale on the S meter yet not open the squelch. And on my radios, when the squelch is closed, the S meter is inactive and shows 0.

Re: [amsat-bb] 12th Annual 13 Colonies Special Event

by Stephan Greene

Speaking of 13 Colonies, I'll be representing Virginia as "K2B" from FM18, and possibly FM19 or FM08 on 7/3 and 7/4 (TBD). I plan to prioritize the linear satellites but will give FM a try if the pass is not too crazy. I expect to be on late afternoon/evenings on the work days and more frequently on July 3 and 4. (July 5 looks to have a lot of family activity, so "staycation mode"). I will try to announce plans on Twitter (hashtags #13Colonies #amsat #K2B). Likely QRG will be 5kHz ABOVE passband center (+/- QRM), computer-controlled. On AO-7, around 145.438-.440 unless there is a rover operating (I'll move up). More info on the event at http://13colonies.us (note new URL from prior years). This will be my first year representing 13 Colonies instead of chasing the stations on HF. All QSL (they have a very nice design for 2020) is through each state's QSL manager (link from 13 Colonies or each call's qrz.com page). If you need my grid or Virginia on LOTW, please tell me, and I'll switch to my own call so we can log it. If you are in one of the 13 Colonies states, it's not too late to contact your state coordinator and join the fun! 73 Steve KS1G FM18 --------- Forwarded message ---------- From: Cal Spreitzer <n3cal(a)md.metrocast.net> To: <amsat-bb(a)amsat.org> Cc: Bcc: Date: Sat, 27 Jun 2020 10:19:12 -0400 Subject: [amsat-bb] 12th Annual 13 Colonies Special Event The 12th Annual 13 Colonies Special Event (Independence Week Celebration) starts Wednesday, July 1, 2020 -1300 UTC and runs through Wednesday, July 8, 2020 (0400 UTC) This will be my second year representing Maryland as "K2F" from FM18. I will be working most FM and Linear birds throughout the week. If you need Maryland feel free to drop me a line for a particular schedule or just tune in. 73, Cal/N3CAL FM18

Field Day submissions

by Bruce

There will be a slight delay in both processing submissions and replying to email submissions. My computer SSD drive died during the night. Everything is backed up to NAS hourly and should not have lost anything. Will try the cloned drive first and then restore the latest files. Of course with an 8-10 year old PC this is a wonderful opportunity to upgrade to a newer PC. I do not like responding I received your submission from my phone because if there is an issue loading it on the PC then you will not be included. I always make sure it is on the PC first. 73...bruce Sent from my iPhone

San Diego Microwave Group - Let's talk about microwave digital broadband on ISS

by Michelle Thompson

Here's an invite to the San Diego Microwave Group zoom meeting to be held this upcoming Monday evening (US Pacific 7pm). I will talk about putting ORI work (payload) on ISS at the meeting to get advice and feedback. This affects ground stations and testing for the payload equipment. This work directly benefits all AMSAT organizations. Being on the ISS was raised as a possibility this past week from the ARISS/AREx hardware summit meetings. The San Diego Microwave Group meeting is a regular technical roundtable on amateur microwave activities, questions, operations, and experiments. You don't have to make a presentation to be part of the call. If you want to be on the SDMG email reflector, send me an email at w5nyv(a)arrl.net and I will make sure it happens. Please forward to anyone you think would be interested. -Michelle W5NYV Topic: San Diego Microwave Group Time: Jun 29, 2020 07:00 PM Pacific Time (US and Canada) Join Zoom Meeting https://us02web.zoom.us/j/81927112936?pwd=UzROZ3MrQnFnTTdFVHgrNjlqaTZ1dz09 Meeting ID: 819 2711 2936 Password: 487697 One tap mobile +16699006833,,81927112936#,,,,0#,,487697# US (San Jose) +12532158782,,81927112936#,,,,0#,,487697# US (Tacoma) Dial by your location +1 669 900 6833 US (San Jose) +1 253 215 8782 US (Tacoma) +1 346 248 7799 US (Houston) +1 929 205 6099 US (New York) +1 301 715 8592 US (Germantown) +1 312 626 6799 US (Chicago) Meeting ID: 819 2711 2936 Password: 487697 Find your local number: https://us02web.zoom.us/u/kcZzwZUYc5 -Michelle W5NYV "Potestatem obscuri lateris nescis."
