Fwd: DMARC Forensic Report for perens.com from IP 172.105.152.211
by Bruce Perens 11 Dec '20

11 Dec '20

I will also send this to the mailman admins, as obviously this message will be filtered by properly-acting servers. The mailman system is not handling DKIM email properly. DKIM is an anti-mail forgery measure. Using DKIM, my server attests that mail coming from me - directly - must be from my own servers, or it should be rejected as below. Mailing list systems mus change the headers to work properly with DKIM. There is information online on how to get Mailman working properly with DKIM.

Mail Server upgrade issues
by David Reinhart 10 Dec '20

10 Dec '20

The only issue I'm having is that I'm getting individual messages vs. a digest. I logged into mailman and it looks like I'm still set to get the digest, but there also appears to be no way to edit the options. Dave, W4DSR (ex-WA6ILT)

Battery chemistry
by David Reinhart 10 Dec '20

10 Dec '20

I can understand why we haven't been using lithium cells up until now, but with the advent of LiFePO4 batteries is it possible they may be suitable for satellite use? Or is the charging cycle unsuitable since it includes temperature monitoring? I know on-orbit is different, but a large number of our local hams are now using these full-time to run their stations, continuously charged by AC or solar panels. In fact, our entire Field Day operation (should we ever get back into the field again) is powered by a bank of these batteries; a 24v bus regulated down to 14 volts at each radio.

Re: How to determine why Fox satellite batteries failed before projected 5 year lifetime
by Stephen DeVience 09 Dec '20

09 Dec '20

I think another lesson here is to consider failure modes and how to keep as much as possible working when a component does eventually break. For example, designing so that after the batteries die the satellite can still work without them when in sunlight (like AO-7 eventually did). Or maybe a way to switch uplink or downlink frequencies if one radio breaks (for example if AO-95 could use L-band in lieu of UHF). Of course with a small cubesat there's not a lot of room for redundant systems, but now that so much is done in software it might be easier than in the past. -Stephen N8URE

Lindenblad
by marzo7088＠yahoo.com 09 Dec '20

09 Dec '20

Hello all.There is a nice article on building a EZ Lindenblad for 2 meters.I like the elevation pattern on the antenna and wondering if it pretty easy to convert to 70CM as well.I know the lengths change on the elements but does the circumference of the wire make a difference.If it is more involved i can always find one for 70CM Thanks Rich
