#2 tone rtty free
I added GRITTY in the mix (tnx Don AA5AU for your excellent tutorial which enabled me to set things up for the test).Īre the tests conclusive? Should they have been done differently (other settings, other hardware)? There are way too many variables to test them all properly - I opted for the simplest setting of very weak, stable and interference free signals (tnx Luc ON5UK for providing the on air signal). On December 1, 2020, I posted a 1st comparison test: (RiTTY-MMTTY).Ī couple of friends suggested the ultimate test would be a comparison between 2Tone and RiTTY. I found some reports on the internet about RiTTY outperforming terminal units, and also MMTTY. I remember not being impressed by using terminal units in the tropics. Earlier in the nineties, I used a PK-232 and KamPlus for RTTY contacts from Africa (9X-EL). Why the testing? In 2000, we used RiTTY during the A52A DXpedition. RiTTY is run with Standard detector, Flywheel Auto, ATC On, Autotune M (500 Hz), Squelch 0.ĢTone-GRITTY and MMTTY are run out of the box (2Tone Squelch off / MMTTY AFC-ATC on, Standard RTTY). note how deep the attenuation was - the RTTY signals were barely audible At 02:48, text (mixed with figures) is being decoded.Īt the end of the video, I undo the attenuation settings. The Marconi RF attenuator then enabled me to proceed in 1dB steps to find the point where decoding becomes erratic (you can hear the clicks of the Marconi when I switch - when decoding gets too erratic on all 4 decoders, I move up a couple dB again until decoding resumes).Īt 00:33" testing with RY-strings starts.
#2 tone rtty 64 Bit
RiTTY V4.5 (K6STI) is run on a Compaq Armada 1700 laptop with an ESS ES1869 AudioDrive sound chip (determined by RiTTY as an 8-bit A/D, Partial Mixer).ĢTone V16.11a (G3YYD), GRITTY V1.3 (VE3NEA) and MMTTY V1.68A (JE3HHT-AA6YQ) are running in N1MM+ on a 64 bit Win7 pc, i7-3770 cpu with 8 GB RAM and a Realtek ALC887 High Definition Audio card.Īudio is taken from the AF OUT and RTTY connectors from the Yaesu FT-1000MP (audio cables have been swapped between both pc's, same result).įirst images are of the RiTTY screen (right) and 2Tone-GRITTY-MMTTY screens (left), moving to the 1000MP (setting the attenuator to 12dB) and on to a Marconi RF Attenuator, bringing the signal further down by 40dB - and cranking up the volume/AF Gain of the 1000mp. This is a new video, comparing RiTTY with 2Tone-GRITTY-MMTTY: īelow follows the explanatory text that goes with the video.
Tnx to Don AA5AU and his excellent tutorial, I managed to setup N1MM+ with 2Tone, GRITTY and MMTTY. Later years we had operation from Montenegro YU6AO and also from Norway LN5O with ON4BPM/SQ5BPM & S53NW during Multi operations in CQ WPX RTTY.After I posted a RiTTY-MMTTY comparison video, some of you suggested comparing RiTTY with 2Tone.
SPØDXC in WPX RTTY Contest was major activity first years.įirst RTTY activity by founder was LI3OWG 1994 by LA5FHA Father and son LB3RE LB3RE (ex LA6FJA), ON4BPM/SQ5BPM in SP5ZCC during WPX RTTY.

The founders of RTTYops had several RTTY activities.įounded in 2004 to save & activate RTTY and engage RTTY activity in DX and Contesting RTTYops had a article in Japanese 59 Magazine by JARTS RTTY Manager 7L4IOU. The RTTYops facebooksite have over 1200 members since 2010, and founded by LB3RE (ex LA6FJA) and WK6I Jeffīiggest RTTY events last 25 years been mostly CQ RJ WW RTTY DX Contest and CQ WW WPX RTTY Contest, other famous RTTY contest been VK SG RTTY Contest, SCC RTTY, JARTS RTTY, SARTG WW, WAE RTTY, BARTG RTTY.Ī few DXpeditions still using/have used RTTY succesfully as over the years. RTTY OPS been founded 2004 by youngsters in WWYC -( World Wide Young Contesters), Its been used in both 45 and 75 baudrate among amateur radio operators passed 40 years.
