Therefore on 30m the kit can be used as a standalone WSPR transmitter. On other bands you may need to supply a suitable crystal for the WSPR frequency on that band. Alternatively you could use this kit in the AF output mode, fed into a conventional SSB transmitter set to the frequency of your choice.<br \/>\n<strong><br \/>\nThe kit supports the following modes:<\/strong><\/p>\n<ul>\n<li>QRSS mode (plain on\/off keyed slow CW)<\/li>\n<li>FSK\/CW mode (frequency shift keyed slow CW)<\/li>\n<li>DFCW mode (dual frequency CW)<\/li>\n<li>WSPR mode (Weak Signal Propagation Reporter)<\/li>\n<li>Slow-Hellschreiber (frequency shifted slow-Hell)<\/li>\n<li>Full-speed Hellshreiber<\/li>\n<li>Half-speed (&#8220;DX&#8221;) Hellshreiber<\/li>\n<li>CW (plain CW)<\/li>\n<li>Customisable FSK patterns<\/li>\n<\/ul>\n<p><strong> Other features:<\/strong><\/p>\n<ul>\n<li>24-character LCD + two-button user interface<\/li>\n<li>User-programmable (callsign, message, speed, FSK, mode, etc.), settings stored in EEPROM<\/li>\n<li>GPS interface, for locking the frequency in slow-speed modes<\/li>\n<li>On-chip generation of WSPR encoded message (no PC required)<\/li>\n<li>WSPR maidenhead locator can be generated from GPS-derived latitude\/longitude<\/li>\n<li>Selectable \u201cframe\u201d size, for stacked QRSS reception<\/li>\n<li>Plain CW callsign identifier at selectable interval<\/li>\n<li>Produces 150mW RF output, or AF output for driving an SSB transceiver<\/li>\n<li>Higher output power by additional PA transistor and\/or higher PA supply voltage<\/li>\n<\/ul>\n<p>The estimate price: 19 EUR or 24 USD.<\/p>\n<p><a href=\"http:\/\/www.hanssummers.com\/qrsskitmm.html\" target=\"_blank\" rel=\"noopener\">Link<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The ultimate QRSS Transmitter Kit is produced by Steve G0XAR and Hans G0UPL in 30, 40 and 80m versions.
