70cm Lindy design files & construction notes available on Thingiverse
by Curt Laumann 21 Oct '20

21 Oct '20

Hi All! Over the last couple of months I’ve been having a lot of fun with 3D printing and design, working to make a 70cm parasitic Lindenblad that is easy to manufacture and assemble. I’d like to share the design files with the amateur community, inviting people to build and improve on this design. This design heavily leverages the previous excellent work by Tony Monteiro (AA2TX), who created and published the paper: “A Parasitic Lindenblad Antenna for 70cm” AMSAT Proceedings 2006. The AA2TX design uses a central driven dipole surrounded by four tilted parasitic elements. One of the biggest challenges to construct the AA2TX design is holding the parasitic elements in the crazy geometry defined by a Lindenblad configuration. The AA2TX design used irrigation parts, requiring careful alignment by hand and tedious bonding operations. Today with the availability of 3D printing it is possible to remove literally all the critical alignments, designing these spacings and angles into the 3D printed part! Design files, pictures and construction notes can be found on Thingiverse (search for my call sign K7ZOO). I welcome any ideas for improvement and would really enjoy seeing the results of any construction efforts. de K7ZOO

Everyone is rushing to put The Cloud into LEO, it seems.

PO-101

So, I've not worked PO-101 before, but when I tried to earlier I was getting no voice. I checked on Satnogs and it appears the same for others with this. Are they not doing FM Voice right now? -- Chris Pohlad-Thomas

G5500 left turn relay failure
by k.swaggart＠charter.net 19 Oct '20

19 Oct '20

My G5500 control box won't command the rotor left, but right works fine. No voltage to the #4 connector when I press "left", but if I put some pressure on the relay the voltage intermittently returns. So, guess the relay contacts are dirty. Looking at the schematic it looks like both the right and left relays are the same, but use different connections. So. thinking I'll just remove and the two and swap relays. (This unit has been in daily use since 2002!) Are these relays available from Yaesu or someone in the US? Did a quick Google and DigiKey search but didn't find them. Just noticed there is a little lid on the top of the relay. When I popped that open there is a lot of black residue on the inside of the lid and I just might be able to clean the contact! Ken, W7KKE

JN15 by F4DXV Monday 19Oct 2000utc RS-44
by john＠papays.com 19 Oct '20

19 Oct '20

jerome, F4DXV, will be operating from a 1500M summit in JN15jo on Monday, 19 October at 2000UTC on RS-44 specifically for North America. The operation has been planned around the coverage of this specific pass such that much of eastern North America will have an excellent chance for a contact with this rare grid. The last 200M of elevation to the summit is on foot. Jerome will arrive at the summit in daylight but will make the descent back to the road after this pass in darkness. Weather may also be an issue. This is not a walk on the beach. Jerome is an experienced operator and will do his best to work everyone that can hear him. Good Luck. 73, John K8YSE
