This guide covers everything you need to know to receive it \u2014 what the system is, what equipment is required, what the GCARC 2.4-meter EME dish would need to work with it, and how to join the global ARISS ground station network.<\/p>\n<\/p><\/div>\n<h2>What Is ISS HamTV?<\/h2>\n<p>The system is known as <strong>HamTV<\/strong> (onboard hardware: HamVideo), a Digital Amateur Television (DATV) transmitter installed in the ESA Columbus module of the ISS. It was originally installed in 2013, commissioned in April 2014, and used for ARISS school contacts from 2016\u20132018. The unit failed in 2019 and was returned to Earth for repair. It was re-launched on SpaceX SpX-30 in March 2024 and reinstalled on July 29, 2025. An updated version was tested successfully in October 2025.<\/p>\n<h3>Primary Purpose<\/h3>\n<p>The primary use of HamTV is for ARISS school contacts, when the astronaut uses a camera to show live video of themselves and the inside of the ISS to a school during a VHF radio contact. Outside of school contacts, the transmitter is frequently left on in &#8220;blank transmission&#8221; mode \u2014 the signal is fully formatted but the video content is black, providing a live carrier for ground stations to tune and test against 24\/7.<\/p>\n<h3>Transmission Parameters<\/h3>\n<div class=\"spec-box\">\n<ul>\n<li><strong>Frequency:<\/strong> 2395 MHz (13 cm \/ S-band)<\/li>\n<li><strong>Polarization:<\/strong> Right-Hand Circular (RHCP) from the ISS patch antenna<\/li>\n<li><strong>Power:<\/strong> 2 W at the patch antenna (10 W EIRP)<\/li>\n<li><strong>Modulation:<\/strong> DVB-S (QPSK)<\/li>\n<li><strong>Symbol Rate:<\/strong> 2.0 Msymbols\/second<\/li>\n<li><strong>FEC:<\/strong> 1\/2<\/li>\n<li><strong>Content:<\/strong> MPEG-2 video with MP2 audio<\/li>\n<li><strong>Altitude:<\/strong> ~250 miles (approx. 400 km)<\/li>\n<li><strong>Max pass duration:<\/strong> ~11 minutes; practical reception window 5\u20138 minutes on a good pass<\/li>\n<\/ul><\/div>\n<h2>Why Is It Challenging?<\/h2>\n<p>This is a 2-watt transmitter roughly 400 km away, moving at approximately 7.7 km\/s. The link budget is far less forgiving than VHF\/UHF satellite work. The ISS is visible from any single location for a maximum of 11 minutes, often less, and at 2395 MHz the signal does not penetrate trees or structures. A minimum elevation of roughly 20 degrees is needed to begin receiving a stable picture.<\/p>\n<p>The ISS is also not geostationary \u2014 unlike QO-100, it moves rapidly across the sky. A 1-meter dish at 2395 MHz has about 8 degrees of beamwidth, requiring accurate motorized tracking. This is the core mechanical challenge of the project.<\/p>\n<h2>HamTV vs. SSTV \u2014 What&#8217;s the Difference?<\/h2>\n<p>It&#8217;s important to distinguish the two ISS television modes. SSTV is easy; HamTV is a serious technical project:<\/p>\n<table>\n<thead>\n<tr>\n<th>Parameter<\/th>\n<th>SSTV<\/th>\n<th>HamTV \/ HamVideo<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Frequency<\/td>\n<td>145.800 MHz (VHF)<\/td>\n<td>2395 MHz (S-band)<\/td>\n<\/tr>\n<tr>\n<td>Mode<\/td>\n<td>Analog FM + software decode<\/td>\n<td>DVB-S DATV \u2014 live full-motion video<\/td>\n<\/tr>\n<tr>\n<td>Antenna needed<\/td>\n<td>Simple whip or Yagi<\/td>\n<td>0.6\u20131.2 m dish + motorized tracking<\/td>\n<\/tr>\n<tr>\n<td>Image type<\/td>\n<td>Still JPEG images (PD120 mode)<\/td>\n<td>Live full-motion video<\/td>\n<\/tr>\n<tr>\n<td>Difficulty<\/td>\n<td>Easy \u2014 any 2-meter radio works<\/td>\n<td>Significant technical challenge<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>Station Performance Tiers<\/h2>\n<p>The community has developed practical guidelines based on your local horizon and available equipment:<\/p>\n<table>\n<thead>\n<tr>\n<th>Performance Level<\/th>\n<th>Min.

Reception has been confirmed on a 60 cm fixed dish (20 seconds of decoded video at &gt;60\u00b0 elevation). The HamTV manufacturer, Kayser Italia, demonstrated excellent reception using a 1.2 m dish during commissioning. A 3-meter dish is completely unnecessary.\n  <\/div>\n<h2>The GCARC 2.4-Meter EME Dish \u2014 An Ideal Starting Point<\/h2>\n<p>The W2MMD clubhouse already has a 2.4-meter mesh dish used for EME operations. This is an exceptional starting point for HamTV \u2014 here&#8217;s why:<\/p>\n<h3>Link Margin Advantage<\/h3>\n<p>A 1.2 m dish at 2395 MHz provides approximately 30 dBi of gain. The 2.4 m dish delivers roughly <strong>36 dBi<\/strong> \u2014 6 dB more signal. That is four times the collecting area of the community standard. This margin is so generous that even a moderately optimized front end will produce excellent results.<\/p>\n<h3>The One Real Challenge: Beamwidth and Tracking Speed<\/h3>\n<p>A 2.4 m dish at 2395 MHz has a half-power beamwidth of approximately <strong>3.4 degrees<\/strong>. The ISS can move at up to 1\u00b0\/second near zenith, giving roughly a 3-second tolerance on pointing error before signal degrades significantly. The rotator must be capable of slewing at <strong>5\u00b0\/sec or faster<\/strong> to handle high-elevation passes. If the current EME rotator is slower than this, low-to-mid elevation passes will still work well \u2014 the ISS moves more slowly at lower elevations.<\/p>\n<h3>The Dish Reflector Is Already Compatible<\/h3>\n<p>A mesh dish optimized for 1296 MHz EME has more than adequate surface accuracy for 2395 MHz. The rule of thumb is surface accuracy better than \u03bb\/16; for 2395 MHz that is approximately 8 mm \u2014 well within the tolerance of any proper EME mesh dish. The reflector itself requires no modification.<\/p>\n<h2>What Needs to Be Added: Component Breakdown<\/h2>\n<p>Since the dish, mount, and rotator already exist, the following components are needed to complete a HamTV receive station:<\/p>\n<h3>1. Feed \u2014 LHCP Helix or Patch, 2395 MHz<\/h3>\n<p>The ISS transmits RHCP. When RHCP reflects off a dish, the handedness flips \u2014 so the feed at the focal point must be <strong>Left-Hand Circular Polarization (LHCP)<\/strong> to receive the signal correctly.<\/p>\n<p>The feed must also be matched to the dish&#8217;s <strong>F\/D ratio<\/strong> (focal length divided by diameter). EME dishes typically have F\/D in the range of 0.35\u20130.45. A feed designed for a shallow dish will under-illuminate a deeper dish, reducing effective gain. Know your dish&#8217;s F\/D before purchasing a feed.<\/p>\n<div class=\"spec-box\">\n    <strong>Recommended feed options:<\/strong><\/p>\n<ul>\n<li><strong>RF HAMDESIGN LH-13XL Helix Feed<\/strong> \u2014 Purpose-built for HamTV, LHCP, weatherproof sealed PVC enclosure. Spec&#8217;d for F\/D 0.45\u20130.5. Widely used by ARISS network stations (~$80\u2013100).<\/li>\n<li><strong>G3RUH Helical Feed Design<\/strong> \u2014 Free plans from AMSAT, suitable for deeper dishes (lower F\/D). Build cost is minimal.<\/li>\n<li><strong>POTY Patch Feed<\/strong> \u2014 Originally designed for QO-100 uplink at 2.4 GHz, confirmed compatible with HamTV reception. Widely available.<\/li>\n<\/ul><\/div>\n<h3>2. LNA (Low Noise Amplifier) \u2014 Mount at the Feed<\/h3>\n<p>An LNA must be mounted <em>directly at the feed<\/em>, not in the shack. At 2395 MHz, even a few feet of coax before the LNA will add noise and degrade the system significantly.<\/p>\n<div class=\"spec-box\">\n    <strong>Specifications required:<\/strong><\/p>\n<ul>\n<li>Noise Figure: &lt;1 dB (mandatory for high-performance station)<\/li>\n<li>Gain: 15 dB minimum<\/li>\n<\/ul>\n<p>    <strong>Commercial options:<\/strong><\/p>\n<ul>\n<li><strong>MiniCircuits ZX60-242GLN-S+<\/strong> \u2014 28 dB gain, 0.9 dB NF. Medium cost, excellent performance (~$80).<\/li>\n<li><strong>Nooelec LaNA<\/strong> \u2014 12 dB gain, 1.5 dB NF. Budget option (~$30).<\/li>\n<\/ul><\/div>\n<div class=\"warning\">\n    <strong>Warning:<\/strong> Very high-gain LNAs (60 dB units such as some Kuhne models) can be easily overloaded by 2.4 GHz WiFi without a filter placed ahead of them. A 2.4 m dish with high gain makes WiFi interference even more of a concern than with smaller dishes.\n  <\/div>\n<h3>3. Bandpass Filter \u2014 Not Optional<\/h3>\n<p>The HamTV frequency of 2395 MHz is only <strong>5 MHz below<\/strong> the 2.4 GHz WiFi band. A strong WiFi burst can cause the receiver to lose lock for several seconds. A bandpass filter is essential.<\/p>\n<ul>\n<li>Use a multi-pole interdigital BPF centered at 2395 MHz<\/li>\n<li>Ideally place the filter <em>after<\/em> the LNA to avoid degrading system noise figure \u2014 but place it <em>before<\/em> the LNA if the LNA is being driven into compression by local interference<\/li>\n<li>If using a downconverter, the filter can be placed at the IF frequency instead<\/li>\n<\/ul>\n<h3>4. Coaxial Cable \u2014 Microwave Grade Required<\/h3>\n<p>Standard RG-213 and RG-58 are not suitable for 2395 MHz. Use <strong>LMR-400<\/strong> or equivalent, or professional-grade satellite coax. Keep the run from LNA to shack as short as practical, or use a downconverter at the masthead (see below).<\/p>\n<h3>5. Downconverter \u2014 Optional but Practical<\/h3>\n<p>A downconverter at the masthead translates 2395 MHz to a lower IF (for example, 731 MHz or 1255 MHz), allowing standard satellite-grade coax and reducing losses on long shack runs. It also enables use of receivers that don&#8217;t tune to 2395 MHz directly.<\/p>\n<ul>\n<li>Spectra Developments SPDC 2400 LNC \u2014 1000 MHz frequency offset, confirms working with HamTV<\/li>\n<li>California Microwave S-band units \u2014 often available on eBay<\/li>\n<li>Nooelec &#8220;Ham It Down&#8221; \u2014 check output IF frequency for compatibility with your receiver<\/li>\n<\/ul>\n<h3>6. Satellite Line Amplifier<\/h3>\n<p>DVB-S receivers are designed for use with satellite LNBs that provide ~55 dB of gain. After the masthead LNA, add at least one inline satellite-grade line amplifier with &gt;30 dB gain. The noise floor at the receiver input should read between -30 and -70 dBm with no signal present.<\/p>\n<h3>7. DVB-S Receiver<\/h3>\n<p>The HamTV signal is a 2.0 Msymbol\/s MPEG-2 DVB-S transmission. The receiver must be pre-configured to the exact frequency and symbol rate before the pass \u2014 any receiver that needs to scan will not lock in the time available.<\/p>\n<div class=\"spec-box\">\n    <strong>Recommended receiver options:<\/strong><\/p>\n<ul>\n<li><strong>BATC PicoTuner (with Serit FTS-4434 NIM)<\/strong> \u2014 USB hardware, tunes directly to 2395 MHz (no downconverter needed), connects to PC via USB. Use with OpenTuner software (Windows) or on a Raspberry Pi 4 with Ryde software. Best choice for new builds.<\/li>\n<li><strong>BATC MiniTiouner Mk2<\/strong> \u2014 Same NIM as PicoTuner, well-proven in the field. Consistently outperforms older TechnoTrend receiver cards in real-world testing \u2014 achieves signal lock 3\u20138 seconds faster.<\/li>\n<li><strong>TBS 6903 \/ 6983 PCIe card<\/strong> \u2014 Most cards in this family tune to 2395 MHz directly. Works in a Windows PC with appropriate software.<\/li>\n<li><strong>High-specification SDR<\/strong> (PlutoSDR, LimeSDR) \u2014 Works well with a downconverter and appropriate DVB-S decoding software.<\/li>\n<\/ul><\/div>\n<h3>8. Tracking Software<\/h3>\n<p>Your existing EME tracking software almost certainly already supports ISS TLE-based tracking. Load the current ISS TLEs from Celestrak or Space-Track and confirm the rotator can achieve the required &gt;5\u00b0\/sec slew speed for high-elevation passes. PSTrotator is widely used in the HamTV community and supports nearly all common rotator interfaces.<\/p>\n<h2>Estimated Cost to Add HamTV to the Existing EME Setup<\/h2>\n<table>\n<thead>\n<tr>\n<th>Component<\/th>\n<th>Notes<\/th>\n<th>Approx.

The 6 dB of extra antenna advantage over a standard 1.2 m station means the front end does not need to be perfect to achieve excellent results.<\/p>\n<h2>Key Pitfalls to Avoid<\/h2>\n<ul>\n<li><strong>Pointing calibration:<\/strong> A 1-meter dish needs pointing accuracy within \u00b13 degrees. A 2.4 m dish requires \u00b11.7 degrees. Account for rotator calibration error, dish mounting, and mast flex\/wind movement.<\/li>\n<li><strong>WiFi interference:<\/strong> Only 5 MHz from HamTV. Intermittent WiFi bursts can cause the receiver to lose lock for several seconds. Filter before the receiver is mandatory.<\/li>\n<li><strong>Cheap coax:<\/strong> RG-58 and RG-213 are not suitable at 2395 MHz. Even cheap SMA patch cables can vary by several dB depending on how they&#8217;re bent.<\/li>\n<li><strong>Falsely advertised LNAs:<\/strong> Some budget units have worse noise figure and less gain than claimed. Stick to MiniCircuits or other reputable suppliers with measured data.<\/li>\n<li><strong>Receiver overload:<\/strong> A receiver overloaded by WiFi may show a strong carrier signal but refuse to lock. If this happens, add or relocate the bandpass filter ahead of the LNA.<\/li>\n<li><strong>High-elevation pass tracking:<\/strong> The ISS moves fastest near zenith. Rotators that can&#8217;t slew at &gt;5\u00b0\/sec will break lock on overhead passes \u2014 though lower elevation passes will still work fine.<\/li>\n<\/ul>\n<h2>Testing Your Station Before a Live Pass<\/h2>\n<p>Because ISS passes are short, it&#8217;s important to validate the system before relying on a live pass. Two proven methods:<\/p>\n<h3>Sun Noise Measurement<\/h3>\n<p>A well-configured S-band station should detect 2.0\u20132.5 dB of sun noise when pointed at the sun. This is an excellent system check for both gain and noise figure. Leave the rotator in solar tracking mode for a few hours and observe the noise level rising and falling as the dish moves through the solar disk. Systems known to receive HamTV detect this range of sun noise.<\/p>\n<h3>Local DVB-S Test Signal<\/h3>\n<p>Generate a local 2.0 Msymbol\/s DVB-S test signal on 2395 MHz using a Raspberry Pi 4 running Portsdown 4 software with a PlutoSDR. Verify the receive chain decodes it correctly before the first real pass.<\/p>\n<h2>Watching Without a Ground Station<\/h2>\n<p>If you want to watch HamTV before building a ground station, the BATC\/ARISS network streams live video whenever any ground station in the network has the ISS in view.
