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.

I've been struggling to get telem downloads the past couple of days.I was hoping to get at least a frame or two to see what the Xmit Power is at. Is it back to low power level again? Mike N7ASZ

Congrats on the Gulf-Alpha. I had one and loved it. Built battleship strong, computer optimized, using a Tee-match. Nothing flimsy about it! The only thing I did stupid was sell it when I had to move. If anyone wants to part with one, let me know! 73, Joe kk0sd -----Original Message----- From: AMSAT-BB <amsat-bb-bounces(a)amsat.org> On Behalf Of Gregory Beat via AMSAT-BB Sent: Saturday, February 29, 2020 9:47 AM To: AMSAT-BB(a)amsat.org; nachif(a)terra.com.br Subject: Re: [amsat-bb] Gulf Alpha Antenna Manual In November 2015, Tim Chapman, KB7MDF owner of Arrow Antennas purchased the VHF, UHF and Satellite product lines from Pete, owner of Gulf Alpha Antennas. http://www.arrowantennas.com/ga.html Arrow Antennas may have kept (or posted) documentation for those earlier Gulf Alpha Antennas. http://www.arrowantennas.com/ greg, w9gb == Assembly and Tuning Procedures for 2 meter – 70 Cm Dual band Circular Polarized Satellite Yagi 1. Unpack and separate all parts, UHF, VHF element rods, retaining nuts for the element rods, T matches etc. 2. Assemble the two boom sections, be certain to match up the V half’s which are on the ends of each boom section. Usually this is the only way they can go together. Sections are marked VHF, UHF. 3. Mount the T matches this way: on the 2-meter end the feed point connectors go towards the front of the antenna. On the UHF part, the forward T match is mounted with the feedpoint connectors towards the front of the antenna, the rear T match has its feed point connector towards the rear of the antenna (see pics on our website) 4. Mount the element rods. The longest rod is the reflector, the Driven Element is the ¼" dia. The element rods mount in descending order of length with the reflector being the longest, Install the nuts as you go. Just snug them, do not apply a lot of torque as it is not necessary. Use wrenches if necessary but just snug them only. 5. Slide the shorting bars onto the T match rods and driven elements. Set the distances as follows for lowest SWR: 2 Meter part: 3 ¼" 70CM part: All the way out (this is the setting for other brands of UHF antennas as well) The above distances are measured from the inside face of the shorting bars to the end of the T matchbox, not the end of the black bushing. 6. Install the boom to mast plate just behind the last 2-meter element and in front of the second 2-meter T match. Can hold the antenna at a 15 degree angle (recommended if you do not have and elevation rotor). The V clamps V parts butt against the mast. 7. Install the phasing cables. We recommend looking at the pictures on our website to see how they install. Be certain to deep any cables away from element rods, as that will detune the antennas. Never allow a cable to run parallel to an element rod. == Date: Fri, 28 Feb 20 21:32:01 +0000 From: Luciano Gasparini <nachif(a)terra.com.br> To: AMSAT-NA BB <amsat-bb(a)amsat.org> Subject: [amsat-bb] Gulf Alpha Antenna Manual Some years ago I bought a Gulf Alpha 2m/70cm antenna from the factory.

SatPC32 difficultly switching to CW
by Tom Schaefer 29 Feb '20

29 Feb '20

I am using SatPC32 on my 9700 with version 12.8d. When I click on the CW- option on screen to switch to CW, the radio does not change. Instead, the title of the window changes to 1524 1504. I thought I saw mention of a patch after revision d but the website indicates no patches. I do have a CW entry in the DOPPLER.SQF file. This happened for different satellites all with a CW entry.

APRS for Android?
by Steve Kristoff 29 Feb '20

29 Feb '20

Does anyone know of an up-to-date APRS app for Android? The original APRSdroid doesn't have very good reviews in the Google app store and apparently hasn't been supported for a couple of years. Steve AI9IN
