DEM L24TX Tx Converter We’ve recently received our L24TX Transmit Converter from Down East Microwave. The unit is compact, simple, and produces up to 25W output in the satellite section of the 23 cm band (1260 MHz – 1270 MHz, actually 24 cm). The L24TX is a transmit-only device that is intended to enable L-band … Continue reading
A major part of our plans for Satellite Station 4.0 includes the ability to operate our home satellite station remotely over the Internet. We’ve been using our Flex-6700 Software Defined Radio (SDR) as a Remote Operating Gateway (GW) on the HF Bands and 6m for some time now. Our latest project is to upgrade our … Continue reading
We recently completed the finishing touches on our new VHF/Satellite Tower. The first step was to install a second set of entry conduits into our shack and a new ground block for our satellite antennas. This involved installing 4″ PVC conduits into our shack. The new entries are very close to the base of our … Continue reading
Frequency accuracy, drift, and stability become more challenging for transceivers that operate at 400 Mhz and above. Our 4.0 Satellite Stations operate at frequencies approaching 1.3 GHz, and we want to be sure that their operating frequencies are accurate and stable. Our Flex-6700 SDR includes a GPS Disciplined Oscillator (GPSDO), so the radio and all … Continue reading
Here’s an article by Nashua Area Radio Society member Mark, KC1IML that explains how to build a PTT switch for remote operation of our station via SmartSDR. Mark and others have been using our station remotely to work DX and operate in the Nashua Area Radio Society’s Student-Teacher Contest Series. Source: PTT Switch for Remote … Continue reading
We have begun looking ahead to Satellite Station 4.0 and where we want to go next after our ARISS crew contact is complete. Our goals for the Satellite Station 4.0 include: A permanently installed version of our 3.1 Station which can be operated remotely over the Internet Upgraded Transceivers which add Pan Adapter/Waterfall display capabilities Enhancements … Continue reading
Software is a big part of most current EME stations. The JT65 Protocol, which was created by Joe Taylor, K1JT, has revolutionized EME operations. It has made it possible for modest single and two yagi stations to have lots of fun with EME. Phase 1 of our 2m EME station software and hardware uses manual … Continue reading
The 6m Band is one of my favorite bands. The combination of its unpredictability and the amazing openings that it can produce certainly makes 6m The Magic Band for me! I haven’t had the chance to work the ARRL June VHF Contest from our home station for several years. A combination of Nashua Area Radio … Continue reading
I’ve had a chance to operate on the 6m DX this past week. We are approaching the prime time for the summer Es (E-Skip) season here in the Northeastern United States. As a result, I wanted to see how propagation on the 6m band might be unfolding during this spring Es season. I was fortunate … Continue reading
I have been operating using the FT8 digital mode on the 6m band using our remote operating gateway quite a bit this summer. The SDR-based remote operating gateway in our station allows us to operate our station from other rooms in our home as well as from outside our QTH via the Internet. When I’m … Continue reading
