Icom 9700 1.2gig (23cm) Mode
by Sloan Davis 28 Feb '20

28 Feb '20

Has anyone experienced any malfunction in transmitting on their Icom 9700 on the 1.2 gig (L-Band Mode)? My SWR’s are registering 3+ and I’ve changed antennas twice with direct connection/ connectors using N adapters. I’m using LMR 400 coaxial (50 foot) run. The power coming out of the radio is 8 watts via dummy load/meter. The antenna is from M2 and requires no tuning. Not sure what else I can do? Sloan (KN4GQB

SATpc32 and IC-9700 operational question
by Michael Walker 28 Feb '20

28 Feb '20

Question on operational methods as I am a new to Linear Satellite QSO's. I have an IC-9700 with a tracking antenna using SATpc32. All work just fine. As soon as I am able to access the bird, I 'net' my frequency so I can hear myself naturally by tuning in the SATpc32 CAT menu as outlined in the manual. I have made a number of qso's and some it is clear they are SATpc32 to adjust both the the both VFO's so that the frequency at the satellite remains the same. However, in other QSO's I have let SATpc32 do its thing, adjusting the VFO's while using the RIT of the radio to chase the other station. That results in our QSO taking up more and more of the bird's bandwidth. My ask to the seasoned group here is am I doing it the right way or is there different schools of thought on this? It seems like you'd want both parties on the same frequency at the satellite at the same time. Thanks in advance and I appreciate any Elmering Mike va3mw

APRS sats with the TH-D74A?
by Steve Kristoff 27 Feb '20

27 Feb '20

Is anyone using the Kenwood TH-D74A, say with an Arrow antenna, to work the APRS sats (ISS, AISAT, etc.)? If so, what are your thoughts? Is it worth a try? Steve AI9IN

Possible amateur radio restrictions at White Sands National Park
by Dan Eggert 27 Feb '20

27 Feb '20

Thanks James KK6MC and Brook N8OCX for the heads up on the possible amateur radio restrictions at White Sands National Park. I have been operating on the amateur satellites for over 2 years now and I am within 15 miles from White Sands National Park, Holloman AFB and the missile range. Based on the information you have brought to my attention I should not have any problems. I will look for any posted signs and see if the Park rangers have any information on the subject. 73 Dan - AC9E Sent from my iPad

Possible UHF restrictions at White Sands National Park
by Dan Eggert 27 Feb '20

27 Feb '20

Thanks James KK6MC and Brook N8OCX for the heads up on the possible Amateur radio frequency restrictions at the White Sands National Park. I have been operating on the satellites for over 2 years now and I am within 15 miles of White Sands, Holloman AFB and the missile range. Based on the information you have provided I should not have a problem. I have been there several times in the past 20 years and I don’t recall seeing any signs on frequency restrictions. I will look for any signs and take pictures if I see one. I will see if the Park Rangers can give me any info on this subject. 73 Dan - AC9E Sent from my iPad

Re: [amsat-bb] Restrictions to UHF operation at White Sands National Park

Hi James, Great information. I remember seeing the signs around White Sands back in the late 80's when I lived in ABQ and liked working AO-27 mobile. Last time I worked in the area a couple years ago I remember seeing the signs again and being surprised they are still there. I think they are located near the beginning and end of Route 70 near White Sands and Alamagordo. Thanks for the reply. Regards, N8OCX -----------------------------------------From: "JamesDuffey" To: cbs045(a)charter.net Cc: "Dan Eggert", "amsat-bb(a)amsat.org" Sent: Thursday February 27 2020 8:15:48AM Subject: Restrictions to UHF operation at White Sands National Park One can legally operate at 50 Watts output or less on 70cm at the White Sands National Park and in the vicinity of White Sands Missile Range, but not on the range itself. So, you should be OK for satellite operation from the park if you stay under 50 Watts. Output EIRP, that is the the type of antenna used, does not matter. Yes, I know that doesn’t make sense. The only outright prohibition on amateur operation in that area is on 902MHz. These restrictions are specified in “ FCC ONLINE TABLE OF FREQUENCY ALLOCATIONS 47 C.F.R. § 2.106” footnotes US270 and US275, available on-line at < [1]https://transition.fcc.gov/oet/spectrum/table/fcctable.pdf [2] > If there are posted signs indicating otherwise in the public access area of White Sands National Park, or public right of way near the White Sands MissIle Range, but not on the range itself, indicating otherwise, I would like to see a photograph of such a sign with its location clearly identified. Of course, on the base proper they can limit your operation as they see fit, as you are subject to military oversight there, but for the public access to the areas around the range, including the park, the restrictions in the table apply. If you are not on the base proper and you stick to Links: ------ [1] https://transition.fcc.gov/oet/spectrum/table/fcctable.pdf [2] https://transition.fcc.gov/oet/spectrum/table/fcctable.pdf [3] http://www.nmvhf.org/restrictions.pdf [4] http://www.nmvhf.org/restrictions.pdf [5] https://www.amsat.org/mailman/listinfo/amsat-bb

Thanks Jackie for the correction. I was looking at the wrong satellite on the frequency guide. That said, for Dan and working AO-91 anywhere near White Sands, beware of the frequency use restrictions. I'm sure others know more about this. 73 de N8OCX -----------------------------------------From: "Jackie Dander" To: "cbs045(a)charter.net" Cc: Sent: Thursday February 27 2020 7:29:11AM Subject: Re: [amsat-bb] Rove to White Sands National Park in DM62 AMSAT site declares U or L is only uplink available for AO-92 and not AO-91.

Re: [amsat-bb] Upcoming SpaceX CRS-20 Launch
by Gregory Beat 27 Feb '20

27 Feb '20

The addition of the ARISS IORS payload entry and it’s prominence in Wikipedia’s CRS-20 page was my editing work, that I just finished last week. I serve as a “WikiGnome”. https://en.wikipedia.org/wiki/Wikipedia:WikiGnome A WikiGnome is a wiki user who makes useful incremental edits without clamouring for attention. WikiGnomes work behind the scenes of a wiki, tying up little loose ends and making things run more smoothly. — greg, w9gb AMSAT-NA, AMSAT-UK == Date: Wed, 26 Feb 2020 06:13:44 -0500 From: <ka3hdo(a)gmail.com> To: <amsat-bb(a)amsat.org> Subject: [amsat-bb] Upcoming SpaceX CRS-20 Launch All, The spouse of ARISS Hardware team member Ed Krome, K9EK, pointed out that the ARISS next generation radio system (InterOperable Radio System--IORS) is prominently described as a primary payload (note: not secondary) on the SpaceX CRS-20 mission which will be launched no earlier than March 6 (ET). See the Wikipedia URL: https://en.wikipedia.org/wiki/SpaceX_CRS-20. The ARISS Team wants to express our heartfelt thanks to all of you that have contributed to helping us realize this major milestone. It should be noted that the ARISS hardware team is still very busy on IORS development and final certification. While certified for launch and stowage on ISS, are still in deep into the final certification of the IORS forflight operations. Also, our build of the second flight unit is in progress in Florida and San Diego. So while CRS-20 represents the launch of SN 1001-our first flight unit--it also represents the beginning of the "ARISS factory build" and certification of all 10 units. ARISS-helping AMSAT and all our partners keep Amateur Radio in Space! Note: November 13, 2020 will represent the 20th year of ARISS continuous amateur radio operation on ISS!! 73, Frank KA3HDO
