QRP is amateur radio slang for 'low transmit power'. QRP digital modes such as FT8, JT9, JT65 and WSPR are modes designed to be transmit and received across the world on low transmit powers (although not everyone uses only low power). The special design of these modes allows even weak signals to be decodable by the receiving software. Released in 2017, FT8 has shown itself to now be the most popular mode by far with JT9 and JT65 taking a backseat. WSPR is also not as active as FT8, although WSPR is more of a beacon mode rather one used

Ameritron Al-811 linear amplifier gives you plenty power to bust thru QRM. You get a quiet desktop linear thats so compact itll slide right into your station -- youll hardly know its there ... until QRM sets in. Conveniently plug it into your nearest 120 VAC outlet -- no special wiring needed. Three tough 811A transmitting tubes, extra heavy duty power supply, all HF band coverage, pressurized ventilation, tuned input, dual illuminated meters, adjustable ALC & more. The first 600 watts make the difference The Al-811 gives you 600 watts PEP output -- thats nearly 2 full S-units over your barefoot rig. That could mean the difference between hearing, "Youre Q-5 armchair copy" and, "Sorry cant copy you, too much QRM." Now you wont have to stand aside while the "big guns" steal your DX. Youll be able to log some of those stations first. Going from 600 watts to the full legal limit gives you less than one S-unit increase. But is that fraction of an S-unit worth the 3 or 4 times more money itll cost you? AL-811 gives you a powerful punch at a price thats easy on your wallet. All band, All mode coverage The AL-811 covers all HF bands. Theres no compromise on WARC and most MARS bands -- you get 100% rated output. You can operate the AL-811 on all modes. Get 600 watts output PEP SSB and 500 watts output CW. You even get 400 watts on demanding continuous modes like RTTY, SSTV, FM and AM. How the low cost 811A tube resists premature failure -- even when your amplifier is mistuned First theyre constructed with widely spaced elements that minimize the chance of touching and causing a short -- even if the plate gets hot enough to melt. Second they use a directly heated thoriated tungsten filament cathode that prevents the electron emitting layer from instantly stripping off -- even if mistuning causes a sudden, sever current overload. The Ameritron AL-811 is excellent for the newcomer because its tough enough to withstand momentary mistuning. And the tubes are so inexpensive t
