Re: [amsat-bb] Elections HEO QO-100' Linear NB + Digital WB
by tokens＠myranch.com 20 Jul '20

20 Jul '20

Joe, I agree with you 100%. Over the years I have heard all sorts of reasons why we can’t do this or that. Although we sure can argue! Specifically I have seen posts on why QO-100 isn’t a good idea. The meantime the guys in the eastern hemisphere are having a great time with their satellite while we argue about what is going on the next Cubesat. I haven’t been active on satellites for a number of years and won’t go into why. But you can be sure if we had something like QO-100 out there I would be active particularly on DATV. Al W8KHP

Recommendation for project website
by Leffke, Zachary 20 Jul '20

20 Jul '20

Hi All, I was wondering if folks had any recommendations for website services for hosting simple project pages. I do a lot of little side projects and occasionally folks ask for more details. I tend to keep things scattered across multiple media (lots on github), and collecting up everything in a 'useful' way isn't very efficient. I've considered making better use of github markdown, but I'm not sure thats the best way to go for all projects, particularly if I want to post a lot of images. Some examples of the types of 'project' sites that I like and am looking to start include the following: https://www.w6pql.com/ http://www.w1ghz.org/ https://destevez.net/ Wordpress seems like it might be a good way to go. For the moment I'm just looking for something simple where I can 'publish' projects a bit better than just posting code or KiCAD designs on github. Eventually I might branch out to this new fangled social media stuff...but for the moment I just want to get the projects written up and posted. Any and all recommendations would be welcome. I'm not opposed to pay sites (mainly to remove annoying ads from the page) as long as the interface is relatively simple and I like the look and feel of things.

AT Golden Packet 2020 success - Maine to Ga at 9600
by Robert Bruninga 19 Jul '20

19 Jul '20

Amsat Rovers might find this interesting: On Sat 18 July in brutally hot weather the 15 mountains were manned from Maine to Ga and APRS packets and messages were exchanged end-to end. Typical Snafu's, I had to turn back 30 mins into my 2 hr trip to go home and get the radio! and another station had to turn back 45 mins in his 5 hour trip to get his coax! The 4000' hike up Mt Katahdyin in Maine was again done by Tim starting at 5 AM and getting back by sunset. Here is report from MDMTN-7 about half way along the mountains: "At 1100 I started receiving packets from the south, including ROAN-3, COMERS-4, AOMTN-5 and HWKSBL-6. As soon as Bob was set up on GDHILL-8 around 1220 (an hour 20m late!) I started receiving from the north, and in about 15 minutes I saw KATHDN-15 flying by." In our 11th year, we now do 9600 and it works fine. And are beginning to invite other mountains within 100 miles of the chain to join us (after the initial end-to-end success). (after 4 hours we usually quit due to exhaustion and heat, success or not!) The one lesson relearned over and over is that you cannot operate mountain top without some kind of helical or cavity filter. You wont hear anything but QRM. I used the dual band DCI filter so that both the voice channel and data channel were fine on a D710 and dual band omni. The main page will be slowly updated! (none yet, we are all recovering)... http://aprs.org/at-golden-packet.html Bob, WB4APR

Election Thoughts
by Robert MacHale 19 Jul '20

19 Jul '20

Board Members should exhibit extreme ownership. Asserting Gender Discrimination or filing Demand Letters is a form of blame and deflection. Perhaps the new members were underprepared. Board Members should spend and hour per month communicating; or more. I hope the feet draggers are replaced. Declining Board Meetings betrays the trust of the group - a dereliction of duty. I still believe the legal expenditures were wise and necessary; the gender discrimination complaint and demand letter were neither. I support newer - more energetic - more innovative board members.

AMSAT: RFI from LED bulbs?
by Robert Bruninga 19 Jul '20

19 Jul '20

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.

Amsat - SOTA
by Oscar Acton 19 Jul '20

19 Jul '20

Hello, I am new to satellite operations. I tried to access Lilacsat2 from a SOTA summit today and failed. I did manage to call into AO-92 yesterday and I was heard by four stations (but I couldn't receive the downlink). I was using a 2m dipole to transmit (I am fairly confident I was getting into the satellite today) and a 2 element 70cm yagi. Now, I think two things went wrong. Firstly, I had no way of directing the antenna accurately (I had to guess on the angle and azimuth), and secondly, the antenna isn't very powerful, is small and isn't tuned brilliantly (it's a 70cm yagi but I get SWR of 2.2 on 70cm). Firstly, I'm wondering how precise you need to be in directing the beam? Can I just hold it in the vague direction that the satellite is approaching from, or do I need to work out the headings? Secondly, I am wondering if my equipment is likely to cut it. As I said, yesterday I was told that my signal was getting in - quiet but fully readable using my Diamond x30. I don't want to transmit if I can't receive in case I talk over someone or cause some interference. I won't be able to buy an arrow or a powerful beam antenna for around a year, but I am really desperate to work the satellites. Wondering if there are any ways that I can use my current equipment in order to work it (whether that be from my Home QTH or from a SOTA summit). I have: Yaesu FT-2980 (2m only, limited to 10 watts) Anytone 868 (8 watts max) Baofeng GT-3TP (8 watts max) 2 ele 70cm yagi 2m dipole diamond x50 collinear at the Home QTH Hoping for some advice.. I would love to hear stories of you working satellites during a Summits On The Air activation, and I would be interested to hear of your station setup (and whether you have had success with a minimal setup like mine). Best Regards, Oscar M7OJA (IO94HT)
