SP3OHM: a DIY IceConeFeed on a Triax dish for QO-100
Michał Słomkowski, SP3OHM, printed and wound the IceConeFeed DIY helix for his QO-100 station in Poland. Three photos of the build on a Triax offset dish, radome off and on.
The IceConeFeed through a Nordic winter
We develop and test our antennas in Bavaria, where a hard winter is a few days below zero. So for the question of how the IceConeFeed handles a real Nordic winter, we asked the operators who run it there. Here is what they report. A note on what the IceConeFeed is, since it matters here:…
A Student’s Journey into QO-100
Adam Laczkó, OM2ADM, an 18-year-old ham from Slovakia, built a QO-100 station as his final school project, with an IceConeFeed from nolle.engineering. Here is how it went. The Beginning: Seeking Knowledge and Support Adam, like many young HAM enthusiasts, was intrigued by high-frequency communication. For his school project, he chose to build a QO-100 setup—an…
IceConeFeed Right Hand Circular!
The nominal QO100 uplink which is using a dish reflector requires a left hand circular polarized (LHCP) feed. This is because the dish reflection mirrors the polarization and turns it from left to right hand as the satellite expects it. But what if you have a dual reflector like OH2JKU in Finland? You need to…
United Nations on QO100 / 4U100QO
From May 18-20 dx-adventure will be QRV on #QO100 from the roof top of the #UnitedNations in #Vienna using #4U100QO. We have donated #IceConeFeed antennas which will later be handed over to the United Nations Amateur Radio Contest DX Club (ARCDXC). Ready for #QSO? Images courtesy and copyright of dx-adventure. Want one? The IceConeFeed v2.1…
Satellite Dish Modification
On rare occasions the IceConeFeed does not have enough mechanical clearance to be mounted on a specific dish arm. In order to check mechanical compatibility upfront you can use the 2D template and the procedure explained here. Paulo, F5VMJ, demonstrates on how to modify the dish arm to make enough room for mounting the IceConeFeed…
IceConeFeed TX Performance
Dieter DC6EH from Kempen conducted a direct performance comparison of the IceConeFeed v2.0 vs v2.1. A continuous 1750Hz tone in USB was sent on 10498.960 MHz. He used the WebSDR http://websdr.is0grb.it:8901 for SNR measurements. Station setup was a 85cm Fuba sat dish. As shown by the spectrum below v2.1 features almost the same transmission performance…
Schulkontakt Antarktis mit IceConeFeed v2.1
Am 22.03.2023 ging die Schulstation DL0CFG der Carl-Friedrich-Gauß-Schule in Friedland OT Groß Schneen QRV mit der Neumayer Station III in der Antarktis und zeitgleich der Polarstern über QO100. Die Station war mit einem neuen IceConeFeed v2.1 von uns gesponsert worden. Dazu schreibt Frank, DL5AAR: Vielen Dank für die Überlassung der neuen Version deiner IceConeFeed. Wir…
IceConeFeed v2.1 bei DATV
Dieter DC6EH aus Kempen berichtet über den Einsatz vom IceConeFeed v2.1 bei DATV: “Die ersten Empfangsversuche sind sehr positiv verlaufen. Nachdem ich die Ice Cone V2 gegen die neue V2.1 getauscht habe, gab es auf DATV eine Verbesserung um +0,8 dB – 0,7 dB. Meine Bedingungen waren der Empfang der DATV-Bake ohne weitere Sendesignale auf…
