https://youtu.be/VCCfEDOBC_U Please Subscribe: https://www.youtube.com/c/SpaceComms1?sub_confirmation=1 I did two passes from Blue Ridge Parkway PK01 EM85 at Craggy Gardens in North Carolina. This is the first one from Saturday July 16th. Confusingly, my first video (featured at the end of this video) is from the second pass on Sunday. I made 14 contacts in this video on Saturday and 10 on the Sunday pass in the other video (https://youtu.be/EyXZ59-t8BQ). Stations contacted: 01) K8YSE 02) N8HM 03) K4FEG 04) KM4ULB 05) W2JV 06) KI4RO 07) WI9I 08) WA5KBH 09) W4DTA 10) N4UFO 11) AA5PK 12) WU2M 13) K5ND 14) W1PA This was filmed on Saturday July 16th, 2016 on the Craggy Overlook Trail on the Blue Ridge Parkway in North Carolina.

MAKI DENKI GTR-1200 23CM Mast Head 10W PA and LNA NF<0.5dB, Gain 23dB, 1296 MHz

MAKI DENKI GTR-1200 23CM Mast Head 10W PA and LNA NF<0.5dB, Gain 23dB, 1296 MHz This item works somewhat, RX yes, TX no, and needs some TLC, but it is complete and unmolested. I am further cleaning out my closets so that I can find my way to the next stage of my ham radio hobby. Frankly I have too much stuff and need to concentrate on a couple projects. http://www.ebay.com/itm/-/162154714460? -- Joe Leikhim Leikhim and Associates Communications Consultants Oviedo, Florida JLeikhim(a)Leikhim.com 407-982-0446 WWW.LEIKHIM.COM

Cubesat mission of the year
by Andrew Glasbrenner 10 Aug '16

10 Aug '16

In conjunction with Smallsat, CalPoly has a survey for cubesat mission of the year. Although Fox-1A isn't listed, there is a write-in opportunity at the bottom of the survey. As AMSAT VP Engineering Jerry Buxton tweeted "@AMSAT Fox-1A launched October 8, 2015. 100% operational with Vanderbilt ISDE radiation experiment and amateur radio 2 way communications." Please visit surveymonkey.com/r/MH8DCJ9 and write-in AMSAT Fox-1A at the end of the survey. The poll closes this evening. Thanks, Drew KO4MA AMSAT VP Operations

Re: [amsat-bb] Es'hail-2 re-scheduled for launch in Q3/2017
by PA3GUO 09 Aug '16

09 Aug '16

Very sorry to see this fantastic new satellite getting delayed! I consider it as a major boost to use of high frequencies by satellite-radio amateurs (beyond the fact that it is a HEO sat). Well, it IS still a great opportunity to look forward to!! Henk, PA3GUO, The Netherlands ---- We have been informed by Es'hailSat Qatar Satellite company, that the launch of Es'hail-2 with the first P4-A geostationary amateur radio transponder is shifted to Q3/2017.

Light duty az-el rotators
by Dave Mann 09 Aug '16

09 Aug '16

I'm going to start using the Arrow dual-band antenna with my FT-736. I've ordered the EA4DX rotor control. Isn't there a combination of inexpensive tv rotators which I can use? I remember using a "pass-thru" rotator set when I was DA1BB; two rotators, one for azimuth and one for elevation. Seems to me I bought them locally. Balanced the horizontal mast with a weight at one end. That set up was with a Fritzel 2-m and 70-cm helical set. The channel master rotors I've seen have a flat base. Looks like Overkill. Any ideas? 73 Dave N4CVX Sent from my iPad

Re: [amsat-bb] Uplink frequency of FM satellites
by Ronald G. Parsons 09 Aug '16

09 Aug '16

I had a little time to test just now before AO-85 got too busy. I was trying to change a lot of things but at the time of the test, uplink 435175 LHCP and LHCP on the downlink was the best. Of course a short time later RHCP was better. "Tumbling Tumbleweeds" Ron W5RKN From: Ronald G. Parsons Sent: Tuesday, August 09, 2016 10:20 AM To: Paul Stoetzer Cc: AMSAT-BB Subject: Re: [amsat-bb] Uplink frequency of FM satellites Thanks Paul, I had heard that AO-85 was lower than the nominal, 435180, and did a short test yesterday. 435180 gave acceptable audio and 435168 produced distorted and noisy audio. I’ll try 435172. The satellite is so busy it’s hard to get a good test in. Ron W5RKN From: Paul Stoetzer Sent: Tuesday, August 09, 2016 4:08 AM To: Ronald G. Parsons Cc: AMSAT-BB Subject: Re: [amsat-bb] Uplink frequency of FM satellites There's nothing to suggest that 145.850 isn't it for SO-50. Measurements after launch showed that the uplink for AO-85 is about 435.172 MHz. 73, Paul, N8HM On Monday, August 8, 2016, Ronald G.
