Polecam zwłaszcza superreakcyjniaka na krótkofalarskie pasmo 2m (144-146 MHz) na BF194*, diodzie pojemnościowej BB105** oraz wzmacniaczu operacyjnym UL1321 (można go zastąpić innym niskoszumnym opampem --> trzeba jedynie uwzględnić inną topologię wyprowadzeń, a pokładowy "wewnątrzbebechowy" tranzystorek, wtopiniony w UL1321, zastąpić "byle czym", ot choćby "uniwersałem" typu BC547, względnie go pominąć, o ile nasz zamiennik będzie miał znacznie wyższe wzmocnienie niż UL1321). Słuchawki powinny być średnio- lub wysokoomowe (przypuszczalnie również i wkładka telefoniczna typu W66 czy W68 także się tu sprawdzi).

TEN RX JEST W STANIE TAKŻE ODBIERAĆ PASMO RADIOFONICZNE UKF ORAZ PASMO OBYWATELSKIE (= CB RADIO)!!!

* oficjalne zamienniki: BF240, BF254, BF494, BF594, ale podejrzewam, że BF214 lub BF215 także tu spokojnie da się wpierniczyć (wszystko oczywiście po uprzednim uwzględnieniu innej topologii wyprowadzeń)

** najlepiej kupić oryginał, ale kapitalistyczna BB909A też powinna tu ładnie śmignąć; generalnie podejdzie każdy varikap VHF/UHF, którego pojemność da się zmieniać w zakresie od kilku do kilkunastu, wzgl. do kilkudziesięciu pF przy pomocy napięć sterujących od 30V, wzgl. mniej, do około 1V); wcale bym się nie zdziwił, gdyby najzwyklejsza współczesna prostownicza 1N4007 tu nawet zadziałała (przynajmniej w paśmie CB)

Gritty.zip

GRITTY 1.3

RTTY decoder for Windows XP/7/8/10, 32/64-bit

FREEWARE

GRITTY is an RTTY decoding program based on the technology developed for the RTTY Skimmer Server project. This is not a skimmer, it decodes a single signal in the 3-kHz audio coming from the transceiver via a soundcard, just like any other RTTY program.

How It Works

The decoding algorithm in GRITTY is based on the methods of Bayesian statistics. This results in a better decoding accuracy than other algorithms, created by the trial and error method, typically achieve. In the Bayesian framework, all information is represented in the form of probabilities. In particular, the Bayesian decoder computes not only the 5-bit Baudot codes, but also the probability of error in each of the bits.

One obvious use of these extra data is to compute the error probability for each character in the text, and color-highlight the unreliable characters. Another use is smart squelching. In GRITTY, the squelch function is based not on the signal amplitude but on the error probability. This works better than the traditional squelch since it allows decoding of very weak signals but suppresses strong signals when interference makes accurate decoding impossible. The net result is very little garbage in the output.

The bit error probabilities are also used in other, more interesting ways. GRITTY not simply prints what was decoded, but performs some intelligent analysis of the decoded text. When similar callsigns appear in the message, an experienced operator can often tell which call is correct and which one is corrupted. GRITTY can do the same, but more accurately than a human, because it can compare the calls bit by bit and merge the probabilities using the Bayes formula. Quite often the program is able to determine the correct callsign and put it on the call stack even if all received copies of the call are corrupt.

A similar approach is used to find and correct the errors in other parts of the text, such as exchange numbers and CQ/DE keywords, to fix incorrect shift state, etc.

Several audio recordings that illustrate the unique features of GRITTY are available on the GRITTY Demo page.
