![]() ![]() LO frequency stability at 23C: +/- 10 kHz Regular Ku-band Satellite TV LNBS suffer from drift in frequency making it more difficult to keep a stable reception for the narrow band signals.īecause of outside conditions (temperature changes, sun, clouds, wind ect). Satellite TV (DRO/PLL-based) LNBS can be used for Es'hail-2, but it is not recommend. Normal outdoor use (25☌), the frequency offset is well within 10 kHz of offset thanks to its integrated 2ppm TCXO and a 25MHz reference. ![]() It does not need a internal modification to receive the narrow or wide QO-100 transponder.Ī second output F (red) is available to benefit from the 25MHz reference signal output in order to control another device or to check the stability. Is stable and precise LNB with a tunable TCXO instead of plain crystal oscillator. Im using my old 1.50 Mtr Primefocus pointed to Astra 23 East for TV Reception.īut offset dishes work off course fine to.īullseye BE01 LNB on the left/bottom so it points to 25,9 East Es’hail-2. It's reception footprint covers Africa, Europe, the Middle East, India, eastern Brazil and the west half of Russia/Asia.Ī joint project by the Qatar Satellite Company (Es'hailSat), the Qatar Amateur Radio Society (QARS) and AMSAT Deutschland (AMSAT-DL).Įs’hail-2 (QO-100) carries two amateur radio transponders, a vertical polarized narrow band linear transponder (downlink 10489.550 - 10489.800 MHz).Īnd a horizontally polarized wide band digital transponder for amateur digital TV DATV (downlink 10491.000 - 10499.000 MHz.).įor reception of Es’hail-2 (QO-100) you need a dish in size 40 - 80 cm for the Narrow Band.Ī size between 80 - 1.20 cm or more for the Wide band transponder is needed. If you decide to keep CW Skimmer, it’ll cost $75.Es’hail-2 (QO-100) is a geostationary satellite in orbit at 25.9° East carrying amateur radio transponders.No flashing or flickering of the frequency in CWS now. After using it for a while I decided to setup CWS (Omni-Rig) with my CI-V cable and seperate COM port. Although it is not a problem, it may be annoying to some. To eliminate it, just increase the I/O Gain in HDSDR. After starting CWS you may hear a tone and see a line in CWS where your marker is.On page 9 of that same PDF you see some steps to get CWS going and talking to HDSDR and the radio. It’s under the Operating Guide section of the PDF on page 8. There are only 6 small steps and I won’t list the changes to it here because they are nicely put together in Icoms PDF. If you followed my previous article, Icom 7610 HDSDR and Icom I/Q Package, that’s a good beginning and you won’t have any trouble. In HDSDR for it to operate with CW Skimmer there are a few minor tweaks that need to be done. That’s it! (see video below) HDSDR Minor Tweaks The Hi-Fi Audio cable properties need to be changed to 16 bit, 192000 Hz. Install them and if the Null Modem Emulator created COM ports with numbers of 20 and under, it’s good to go and I think this is usually the case. There was really not much to it.Īll of the download links are in the document. To get started on this little project you need CW Skimmer, Null Modem Emulator, Hi-Fi Audio Cable installed and setup. See my previous article on HDSDR, you need it going first. If you like CW or want to learn more about CW, this is a program that will help.ĬW Skimmer, Null Modem Emulator, Hi-Fi Audio Cable The decoding on CW Skimmer (CWS) is amazing. After having it for a while I decided to give CW Skimmer a try and wow! Not only easy, but it works so good. See my article: Icom 7610 HDSDR and Icom I/Q Package. First I installed the Icom 7610 I/Q package for HDSDR and got it working. Icom has really made it easy to have CW Skimmer working with the Icom 7610. ![]()
