| QRSS - powolna telegrafia |
| Jurek, a zwarłeś wolne nóżki procka do masy, miałem podobne objawy, że się prędkość kluczowania zmieniała i chyba też raz ustawiła się na 15 Some builders have reported that the keyer chip does not correctly enter the QRSS mode they selected. There is also sometimes confusion about the 12wpm callsign ID. The proper operation is for the keyer to issue your callsign once in 12wpm CW when you power up, then drop back to the QRSS mode you have selected. If you do NOT get the QRSS mode that you expected from your pin 5, 6, 7 settings, then there could be a problem with the specific AVR keyer chip or the environment it's operating in (e.g. RF around etc), that causes the chip to falsely recognise the input pins as high when you have not connected them. The solution to this problem is, either: 1) Connect any of the unused select pins 5, 6, 7 to ground if you haven't connected their jumper, i.e., don't just leave them floating; OR 2) Connect a 10K (or so) pull-DOWN resistor from each of pins 5, 6 and 7 to ground, to ensure again that none of the pins are left floating. |
