Sorry for the QRM on SO-50
by k3sv＠pa.net 09 Feb '15

09 Feb '15

I apologize for the QRM I caused on SO-50 a few minutes ago. I had my 440 preamp in the "off" position and was not hearing. I should not have been transmitting when I didn't hear. Sorry for the confusion I caused and the QSO's I may have wrecked. 73 Bill K3SV portable in EL99

Hi Bernie, Guess I was wrong! Checked my 1978 log, and I see that I worked them on 20, 40 and 80 meters, but not on OSCAR. Congrats to those who worked them. 73 Ray W2RS

Jeff, As far as I am aware, none of the previous Navassa operations made any satellite contacts, so if/when K1N gets on the bird, it will be an ATNO (all-time new one) for everyone. GL, Ray W2RS

K2BSa/5 active on SO-50 this coming Saturday 2/14
by Tom Schuessler 08 Feb '15

08 Feb '15

Hi all, We are doing another Radio Merit Badge workshop at the National Scouting Museum in Irving, Texas, EM12, this Saturday, Feb. 14th. We will again be activating the callsign K2BSA/5 for the activities which will include a SO-50 pass at 2205Z AOS. This will for us be a 49 degree westward elevation that should touch almost all of the continental US. Please give us a call and give a group of Boy Scouts and parents a thrilling cap to our day. We will also be active on HF (Probably 20 or 15 meters near the World Scouting Frequencies) during the afternoon hours (CST) as well as local VHF and can be reached on Echolink by looking for the WA5CKF repeater. Email me if you want to set up an HF schedule. Looking forward to working some of you on SO-50. Tom Schuessler, N5HYP n5hyp(a)arrl.net

RS demise - taking back 11 meters?
by Robert Bruninga 08 Feb '15

08 Feb '15

Here is an idea. Radio Shack was the #1 seller and supporter of CB radios. But as they close down, there remains a few BILLION dollars worth of 27 MHz spectrum sitting on the table. Why not come up with a proposal for the FCC to give it back to HAMS? What for? That is the BIG question. Its wavelength is IDEAL for mobile operation. And HAMS love making use of old radios. I do not want this to smack of self-interest, but APRS seems like a pretty good use of a channel. And it does not involve speakers having to listen to foul language.. So what is the KILLER APP for 11 Meters? How do we make it happen? Does anyone know of any "under used channel" for experimentation? Who would like to get an STA from the FCC to "experiment? We already have a space segment at 29 MHz, and I dont think that AM is of much use for satellites... so I have no ideas for specific AMSAT applicatiojns.... But how could we u se all those $5 radios and antennas at flea markets..... Bob, Wb4APR

FUNcube Data Warehouse outage
by David A B Johnson 07 Feb '15

07 Feb '15

Hi, Further to my message this morning regarding the outage between 01:50 and 08:50 UTC, I can conirm that 616 unique packets (1268 before deduplication) in total from 20 users were received by the warehouse. Their dashboards uploaded the data automatically when the data server came back on line. Current Stats. since deployment: 444 days in orbit Satellite has transmitted 7672320 packets (1.96GB + FEC) 1868015 distinct packets stored in warehouse db (478MB) Worlwide Packet recovery: 24.3% G/S have uploaded 7980389 packets (2.04GB) before deduplication On average, 4 g/s are receiving each packet when the satellite is in view of a major area of population. As always, thanks our many groundstations for uploading data. 73 Dave, G4DPZ FUNcube Team Member

Re: [amsat-bb] Splitter for receiving system?

Thanks to all the great replies and suggestions on this splitter thing. I ordered a pair of these Mini Circuit units (surplus, stateside) to have in the shack, and will try out when they come next week: http://www.ebay.com/itm/270725394050 For my application, should work fine. Just has to be better than a TV splitter, if for no other reason than 75 ohms vs 50 ohms, SMA can be used here with fewer adapters, etc. :) Mark N8MH >Hello All, > >I am really wishing for a "splitter" for my receiving system, good for both >2M and 70cm (so say, 144-450MHz or so.) > >Any suggestions?
