Es’HailSat-2 with two geostationary “Phase 4” amateur radio transponders The Qatar Amateur Radio Society has presented to Es’ Hailsat, the Qatar Satellite Company, a concept and specification for an amateur radio payload on the new geostationary communication satellite Es’HailSat- 2 presented. Based on this specification, Es’ Hailsat announced that amateur radio transponders will be on board.
Es’HailSat-2 will have a 250 kHz wide linear transponder for conventional analogue operation as well as an 8 MHz transponder for experimental digital modulation modes and DVB-ATV.
The exact uplink and downlink frequencies are not yet finalized. However, it is clear that the uplink in the range 2.400 to 2.450 GHz and the downlink in the range 10.450 to 10.500 GHz will be within the respective amateur radio assignments. The antennas of both transponders will have large aperture angles, so that the maximum possible area, ie about one third of the earth’s surface, is covered.
Exact technical parameters will be set within the next few months. It is expected that only a relatively simple station equipment is required for operation over this satellite.
This groundbreaking project will trigger a phase of new, exciting amateur radio activity. The technical expertise is provided by a team of radio amateurs led by Peter Gülzow (DB2OS, AMSAT-DL President).
Steel City ARC will be holding it first testing session on April 7, 2018 at 10 AM at the club house. To make sure we have enough testing material for the testing session we are requiring preregistration by March 26th. Please visit the VE Testing web page for more information and how to contact Art, WA3BKD
SKYWARN® is a National Weather Service (NWS) program developed in the 1960s that consists of trained weather spotters who provide reports of severe and hazardous weather to help meteorologists make life-saving warning decisions. Spotters are concerned citizens, amateur radio operators, truck drivers, mariners, airplane pilots, emergency management personnel, and public safety officials who volunteer their time and energy to report on hazardous weather impacting their community.
Thursday night at 9 pm Eastern on the next episode of Ham Talk Live!, Rob Sherwood, NC0B of Sherwood Engineering will be here to talk about his latest analysis of receivers, including the new Icom 7610. We will talk about comparing the 7610 to the 7300 and other receivers, and answer the questions that are sent in advance. (Questions were taken in advance on social media this week due to scheduling conflicts for live Q&A).

Wondering how popular the new digital mode FT-8 mode is getting? We downloaded the logbook from the WSJTX program on just the Kenwood TS-590 rig. This one radio had over 952 QSO with other FT-8 users from around the world. I have broken down the log by the different bands and have sorted the list by call sign. I have also included the complete logbook in Excel format if you want to dig it down farther.

At 06:50 UTC on November 23, 2017, AMSAT Engineering officially commissioned AO-91 (RadFxSat/Fox-1B). AMSAT Vice-President Engineering Jerry Buxton, N0JY, turned over operation to AMSAT Operations in a QSO on the AO-91 transponder with Mark Hammond, N8MH, of the AMSAT Operations team during the pass over the Eastern United States.
N8MH responded and declared AO-91 open for amateur use!
AO-91 was built as a partnership with Vanderbilt University ISDE and hosts four payloads for the study of radiation effects on commercial off the shelf components. The satellite was launched on November 18, 2017 as part of the ELaNa XIV mission, secondary payloads aboard the Delta II rocket that carried the Joint Polar Satellite System (JPSS-1) satellite to orbit. AO-91 also features the Fox-1 style FM U/v repeater with an uplink on 435.250 MHz (67.0 Hz CTCSS) and a downlink on 145.960 MHz. Satellite and experiment telemetry are downlinked via the “DUV” subaudible telemetry stream and can be decoded with the FoxTelem software.
