Hi All, I spent both Saturday and Sunday morning on 6 cm in the ARRL microwave leg. I QSO'ed F2CT#, IK2RTI#, SV1BTR, PA0BAT, K5GW and G3LTF. I heard W5LUA, LX1DB (SSB), OH2DG, SV3AAF, SQ6OPG, IZ2DJP and VE6TA. Some of them were called with no response and some of them I never heard calling CQ nor answering my faint CQ's. I never heard K1JT (K2YUH) on the band, pity. It is very hard to be on all bands at the right time. Some loss is to be expected with this form of contesting. I do admire the stations who are running many bands in the contest. My window ended 1140Z on Saturday and 1150Z on Sunday when the moon hit the trees to the west. F2CT acted as a great beacon all the moon passes with a very nice signal. I am now using the OE5JFL auto-tracking. It is a great relief on 6 cm compared to manual tracking with a beam width of 0.66 deg. I now get time to actually work stations, not only tracking the moon :-) 6 cm was kind of slow at times during Sunday so I could just leave the antenna tracking the moon, the radio scanning the band and do other things in between. I picked a cup of ripe blackberries just outside the shack, they are now submerged in vodka and will be this years X-mas snaps :-) The sloe (blackthorn) is not ready for the same procedure yet, they need some good frost first. I made some SDR recordings that can be down-loaded from my web page. They play in the SDR-Radio or HDSDR SDR software. http://www.2ingandlin.se/29-Sep-2013 1055 28.100MHz 000.wav<http://www.2ingandlin.se/29-Sep-2013%201039%2028.100MHz%20000.wav> http://www.2ingandlin.se/29-Sep-2013 1039 28.100MHz 000.wav http://www.2ingandlin.se/28-Sep-2013 1012 28.100MHz 000.wav<http://www.2ingandlin.se/29-Sep-2013%201039%2028.100MHz%20000.wav> In all these files you can see the whole band from 5760.055 to 5760.145 MHz using a SDR software. You can pick any station you like to listen to how it sounded from my horizon. The files are from 30 to 50 MB in size. A poll among the microwave moonbouncers: *How many of you are using a SDR to monitor the band?* It would be interesting to know. I find it as a very nice way to keep tack of what is happening on the band. 73 / Ingolf, SM6FHZ -- Ingolf, SM6FHZ http://www.2ingandlin.se/SM6FHZ.htm

Elevation sensor with MMA7361 ?

by Les Listwa

Hi Marco, I have not played with the MMA7361, but have built an Arduino based AZ/EL Rotor Control for the G-5400 based on K3NGs code. His code supports the ADXL345 accelermeter and the HMC5883 digital compass. The challenge seems be sending the data from the accelerameter long distances to the Arduino for display and control but I understand that could be down by having a master and slave Arduinos connected via Cat5. Please let me know what you learn as I am interested as well. 73 Les W2LPL

Microwave weekend results G3LTF

by Peter Blair

I spent about 90% of my available moon time today on 9 and 6cm. Yesterday I was on 13cm. The round trip from the shack to the dish and back is 100m and I must have walked that at least 20 times today, I think I changed feeds about 6 times... but it was very worthwhile. I think activity was a bit up on last year and I also had the added effect of my dish surface improvements. I hope everyone enjoyed the weekend activity as much as I did. I worked the following: 13CM OK1CA, HB9Q, UA5Y, ON5TA, SD3F, JA4BLC, SP6OPN, OH2DG, SM3JQU#, SV1BTR, YO2BCT, OK1KKD, MJ/DL1YMK, SM6CKU, SV3AAF, PA3CSG, OZ5G, IK3COJ, PA0BAT, OZ4MM, S50C, DL7YC, CT1DMK, LZ1DX, HB9SV, K1JT, OH1LRY, NA4N, K5GW, WD5AGO, VE6TA, DF3RU, F5JWF, PA3CQE#, G4RGK, PY2BS, KL6M, LA8LF. 38X28 ( 2012 34 ) Gotaways were WA6PY, WA9FWD cwnr and ES5PC hrd. 9CM MJ/DL1YMK, PY2BS, OK1CA, SP6OPN, ES5PC, W5LUA, HB9Q, K1JT, WA6PY. 9X9 (2012 4) 6CM K5GW, SM6FHZ, SV1BTR, SV3AAF, F2CT, W5LUA, K1JT, VE6TA. 7X6 (2012 9) Thanks to all for the QSOs, 73 Peter G3LTF

Looking for Write-ups to the Jamesburg EME operations, in DUBUS or other publications.

by Patrick Barthelow

Friends, I am looking for a reference or link to any writeups to the Jamesbug EME operations of 2006-2008. Can anyone supply a Month and year, of any DUBUS write-ups for Jamesburg? Or for that matter, any write-ups other than those in CQ-VHF ? Thanks, 73, -- Best, Pat Barthelow AA6EG apolloeme(a)gmail.com Google Lunar X prize Team, SYNERGY MOON wwww.synergymoon.com

Elevation sensor with MMA7361 ?

by HB9CAT

All, just to avoid reinventing the wheel, did anyone build an antenna elevation sensor based on the MMA7361 chip ? It just costs a couple of bucks and seems fit for purpose providing analog outputs. It could be coupled with an arduino to provide for example digital display and/or remote control. 73, Marco HB9CAT

Microwave weekend

by Manfred Ploetz

Hello lunatics, last week I had the chance to work M&M`s Jersey expedition with MJ/DL1YMK callsign, first at 9cm and the next day at 6cm. Thanks Micha for the contacts and Monika for your excellent dish tracking by brain and hand !!! Saturday and Sunday was followed the ARRLmicrowave contest. For the first day I decided to start at 6cm, because I am a lazy guy and the 6cm feedbox was allredy installed. But with not so much success like last year and less activity on that band I worked only: F1PYR and IK2RTI.... ....therefore I decided 0500 UT to change to my 12cm feedbox.(due to the news in the HB9Q chat !) I used this brand new feedbox (OK1DFC feed/250w SSPA/G4DDK 027dB preamp) for the first time. It was a real mechanical setup, because from 24 GHz I know the dish`s focus very well No sunnoise was made before and the moon-noise is just detectable with my 2.4m dish. I started with echo testing – and, I heard them ! Bingo ! The first contact was made with HB9Q (thanks Dan, this was armchair listening). Later followed the next big gun: G3LTF and than SV1BTR, PY2BS, PA3CSG, HB9SV, after that I had a call from someone at 9:50 UT, but I couldnt`identify. I heard F1PYR too –no contact was made. But the main experience was the M&M qso (again wit MJ/DL1YMK call) at 12cm !!!!! Next day I had changed to 3cm and made 13 contacts at 10 GHz. OK1KIR, PA7JB, DL0EF, F5JWF (new #), F1PYR, UA5Y (new #), UR7D, OZ1LPR, DL0SHF, someone called me 08:08; again not identified, sri, followed IZ2DJP, SQ6OPG, LX1DB, .....and... finally.... MJ/DL1YMK with OOO reports. (new #) Heard but not worked where: PA0SSB, SP6JLW, and some “marginal” station – to low signal levels for my small 2.4m dish. Thanks to everybody for new and “old” contacts. See you next time at any band from 2304 to 24048 MHz ???? vy 73 Manfred, DL7YC

Microwave weekend results

by jimmyv＠hol.gr

Thanks to all for the joy of eme in arrl microwave contest section. Operated on 13 & 6cm cw random (no microwave logger presence/coordination, active/passive) and wkd the following: 13cm: 40 - missed 6 stations - (2012 39) and 6cm: 9 (2012 19 , 2011 14). My 6cm signal was 5db weaker which did not stop me from calling CQ or working all who called me (have no SDR and the like), even though intense libration & apogee were not helping. A nice weekend with the downside of much less activity on 6cm this year, at least the super plenty of time I was on. It is a pity this happens probably because 2.3 & up seem to have had non-stop logger liaison coordination (allowed). Something I am personally against in a contest when moon is visible. Regardless of number of bands on a single weekend (can be max 5 bands while in Oct-Nov legs is 4 bands where liaison is correctly not permitted, so what’s the big deal..). Such means have certainly resulted in lowering overall cw random activity/cq without prior notice, in last years. On Sunday’s moonset I was so tired that for 30 mins I could not hear echoes on 13cm and was checking station till I noticed Doppler being 6KHz off.. thinking I was on 5.7 (1 digit difference in the alternate vfo) ….hi This brought back memories from the time I became qrv on 13cm and in my first echo tests on that band I was copying nothing for 15 mins…got constructively stressed till I discover I had forgotten to connect the tx feedline… Funny stories which revive the nice feeling of a newbie. At least no medical accidents this year J See you in Oct-Nov legs of 50-1296MHz. 73 Jimmy SV1BTR Ps. Next year plan to run 3cm also, same operational style, pity we don’t have 9cm here to run 4 bands on a mw weekend.

Re: [Moon-Net] [Moon] ARRL microwave results JA4BLC

by Eric Van Offelen

Hi Yoshiro, Thank you very much for the 13 cm QSO. The interference problem in my area is still the same as past years and makes reception in the 2424 segment very difficult. Seems it is getting better in some areas, but not here... Happily, your signal was excelent and could be easily copied between all the "clicks" and noise bursts. I tried very hard to listen to the other JA stations and only copied briefly JA8ERE. Thanks to all for the QSOs and for a very lively and enjoyable contest ! GL & 73 de Eric ON5TA Original Message ----- From: "Yoshiro Mataka JA4BLC" <ja4blc(a)web-sanin.co.jp> To: <moon(a)moonbounce.info> Sent: Sunday, September 29, 2013 11:55 PM Subject: [Moon] ARRL microwave results JA4BLC I operated 13cm and 3cm this weekend, not easy as both bands are separate segments from Japan. On 13cm I worked SV1BTR,SP6OPN,G3LTF,ON5TA,MJ/DL1YMK,K1JT,WD5AGO OK1CA and DF3RU #. Heard many stations on 2320 and JA8ERE on 2424. On 3cm I worked OK1KIR on 10450 and heard UA5Y on 10368. Thanks to all for the cross segments QSOs.
