¿ªÔÆÌåÓýI found the same thing with a straight key, decent performance with a paddle. Yes, the pops going into transmit are a bit annoying. Perhaps a simple transistor switch to break the audio connection could be a mod to pursue - the KK7B R1 and R2 circuits used a 2N7000 transistor for this. A little research into the cause will probably find a cure. Pretty amazed with it as it is - haywired it on the table and it's working pretty well. Operation is intuitive. However, I can't get the CW tone to change - hitting PTT doesn't seem to set it as the screen says. So I can't move that yet. John K0JD On 12/20/2017 15:41, Jim Sheldon wrote:
Definitely a loud POP in both the headphones or a speaker if plugged in.? It is very annoying and occurs on both the PTT keying transition and on the first dot of the CW keying transition.? Also, the paddles are very difficult to send CW with as the keyer chops the first dot and the timing is NOT consistent between the dot and dash transitions in the keyer.? I've been a mostly CW operator for over 50 years and this rig will not meet my specs as a CW rig until that is fixed.? Also the hand key doesn't always key right either.? I polished the paddle contacts and the hand key contacts til they were squeaky clean.? They work perfectly with my Elecraft K3S giving no errors (that I don't make myself) in keying so they should do well with this rig too, but they don't.? The hand key occasionally will trigger the keyer into dots or dashes when first pressed.? |
