Arrow Antenna and Loctite
by Brad Smith 29 Jan '20

29 Jan '20

<The screw-on elements are subject to coming lose with vibration, so one would need a way to permanently tighten them (lock-tite on threads?).> Replace the steel threaded rods with stainless steel threaded rod or studs. Available from local hardware store or McMaster Carr. If you want to use Loctite, only use "Removable Loctite 242" for very obvious reasons. You can buy Loctite at McMaster Carr. By the way, the threaded rods are 8-32 thread size. I like to use stainless steel wave washers at each connection to the square tube, but that is because I don't use Loctite on it and the elements do loosen up. Everything is available at McMaster Carr. The threaded rod is available in one foot pieces that have to be cut or as studs. Brad Smith KC9UQR

Error accessing FunCube Pro from FoxTelem
by James Jipping 29 Jan '20

29 Jan '20

Good Evening! While attempting to use my FunCube Pro directly from FoxTelem I get an error: LIBUSB_ERROR_NOT_FOUND. An internet search has found mentions of the error but no solutions for my situation. I am using Windows 10 for the OS on my comupter. Any thoughts or suggestions ?? By the way, I use SDRConsole and feed the audio via VB_Audio Virtual Cable with GREAT results. I even have RSDConsole with WispDDE running the antenna rotor controller. I thought I would try the direct feed FoxTelem- to-FunCube before I set up My Raspberry Pi for "Fox-in-a-Box" One last question, while I'm here: Is there any way FoxTelem without SDRConsol, with a DDE program , could run the rotor controller? Thank you for you help. Jim Jipping, W8MRR AMSAT # 5512

Arrow Antennas for terrestrial work
by John Geiger 29 Jan '20

29 Jan '20

Most of the reviews I have seen for the Arrow Antenna dualband yagis are regarding their use on the satellites, which I think is what they are mainly made for. Has anyone on the list used one of their dualband antennas mounted permanently for terrestrial work as well? They do sell a mounting bracket for permanent mounting to a mast. Do they seem well made enough to withstand the outside elements for a few years on end? Do they seem to perform as well as other antennas which have approximately the same boom size and number of elements? 73 John W5TD

SSB Electronics has mast mount preamps that some people prefer over ARR, that I assume are comparable. But my googling produced a website that has an error loading. 73, John Brier KG4AKV On Tue, Jan 28, 2020 at 4:05 PM Steve A <onmontauk(a)gmail.com> wrote: > > Now that Advanced Receiver Research has stopped production, is there a suitable replacement?

John, Not for permanent home station use, but I have used the six UHF element Arrow as part of a rover in VHF Contest operation: http://www.kl7uw.com/RoverJune06.jpg On the far side of the crossboom. Had to mount facing sideways as the 3-element 6m beam was too wide to be street-legal. No rotator (used truck). Also six element 2m and 18 element 900-MHz loop yagi. Made 81 mile contact using 15w on 927.50 FM from local 400-foot hill. The screw-on elements are subject to coming lose with vibration, so one would need a way to permanently tighten them (lock-tite on threads?). 73, Ed - KL7UW From: John Geiger <af5cc2(a)gmail.com> To: VHF Contesting Reflector <vhfcontesting(a)contesting.com>, VHF Reflector <vhf(a)w6yx.stanford.edu>, AMSAT <amsat-bb(a)amsat.org> Subject: [amsat-bb] Arrow Antennas for terrestrial work Most of the reviews I have seen for the Arrow Antenna dualband yagis are regarding their use on the satellites, which I think is what they are mainly made for.

Arrow For Other Uses
by Brad Smith 27 Jan '20

27 Jan '20

I have used my Arrow to contact repeaters and for simplex. Works fine. I would replace the studs and screws with stainless and also place bronze wave washers between each element and the boom. But, I don't know about leaving it out in winter weather. Brad Smith KC9UQR

Crew packing Cygnus for departure (and launch of HuskySat)
by Chris Thompson 27 Jan '20

27 Jan '20

https://blogs.nasa.gov/spacestation/2020/01/27/science-soon-resumes-on-cosm… The space station blog says that the crew are packing the Cygnus for departure. It's my understanding that it will boost to a higher orbit and release its small sats, including AMSAT-NAs collaboration with the University of Washington - HuskySat. ( http://www.arrl.org/news/huskysat-1-successfully-lifted-into-space) So it you want to collect telemetry on 70cm from a cubesat, using FoxTelem, then this is your chance. Prepare your station for reception. The blog says that the Cygnus spacecraft will depart "at the end of the week". 73 Chris -- Chris E. Thompson chrisethompson(a)gmail.com g0kla(a)arrl.net
