To all the gents who were on the last pass of AO-51. Joe (SZH) was listening but is having transmitting/antenna issues. Dale I heard you near my LOS, better luck next time. These "different" modes are fun and usefull for checking out new equipment projects . The usual list of characters (YSE, ELU) and a few others are always good to hear. Thanks Drew. 73 Bob W7LRD

Cute 1.7 Re-entry
by John Heath 14 Oct '09

14 Oct '09

Not Yet Perigee Height is now below 200km but Cute 1.7 Object #28941 is still in orbit Re-Entry predictions for around mid day October 13th from EI7IG and W7LRD therefore drop out of the competition. Is she staying aloft long than expected because of a high mass to surface area? 73 John G7HIA

That can backfire and waste time, due to people not understanding the letters. For example, my callsign under adverse conditions could be mis heard as (heard most of the following on terrestrial repeaters or IRLP/Echolink, let alone on the birds!): VK3JEB VK3JD VK3JB VK3JEV VK3JV And the list goes on.... ;) The overhead in asking for clarification or getting a correction outweighs the overhead of using phonetics in most cases. Once callsigns are confirmed, you can drop the phonetics (though usually by then, the QSO is over, so someone else can have a go ;) ). Phonetics are also more likely to survive brief bursts of QRM or brief fades. 73 de VK3JED / VK3IRL http://vkradio.com

Hello, Some offer to sell these here. I thought I would offer to buy one. I am looking for the handheld version with the reflector if anyone has decided they have had enough. Charles AA1VS

WTB: EZ-Lindenblad antenna
by Samudra Haque N3RDX 13 Oct '09

13 Oct '09

Hello is there a commercial source of EZ-Lindenblad antennas for mounting on a convention A-frame rooftop ? I have read AAT2X's paper describing how to homebrew, but want to look at buying a pre-built version to get started quickly with no need to rotate/elevate on the RX side. Regards, Samudra, N3RDX

Bob, Just saw the message about L band being activated and checked it out on the morning western pass. Signals were much stronger on 435.300 than they were on 435.150 and I do have polarity switching. Seems like more than 3db. No one was on the 1303z pass but if you are full duplex, you can always talk to yourself. I had good copy with 10 watts and your 13T Helix all the way down to 1 degree (my best direction, southwest). The only thing more power and a bigger antenna would achieve would be to overcome the radar interference. No radome on the antenna; we'll leave it this way over the winter and see what happens when there is snow and ice. John K8YSE

This is a quick heads up for two excellent North American mid-continent ISS passes conducting ARISS School QSOs. 145.800 MHz is the downlink. First one is today, Tuesday - and next opportunity on Wednesday. Boundary Beach Elementary, Delta, BC, Canada on Tuesday 13th October at 17:10 UTC. This is a direct contact via VE7LHM Glenmore Christian Academy, Calgary, Canada on Wednesday 14th October at 16:01 UTC. This is a direct contact via VE6BGC.
