The timing is different to Yaesu, that’s for sure, I’m great with my MTRs into the 30’s WPM but I can’t key my FT817 at that speed! I’m not saying any particular rig is better, just that there is a difference and I’m used to the MTR.
Quote from Steve Weber, the MTR designer -
" “A” mode doesn’t have dot or dash memory, which makes it very easy to drop dits and makes squeeze keying almost impossible.
“B” mode remembers that you closed the dit or dash paddle before the current element has finished sending. Now if you squeeze both paddles, it remembers that fact and completes by sending the last dit or dah opposite of the element being sent when you release the paddles. This makes sending characters which end with a dit -dah or dah-dit quicker like C, K, R, N, A, P and do on.
The MTR Is “B” mode
The memory is only active while the dot or dash is sending, not during the space between elements. If the memory is active during the space, you timing becomes even more critical especially at higher code speeds which can result in inserting unwanted trailing elements.
But at slower speeds, dropping a dit can become more of a problem due to “keying ahead” a little too fast.
I have a Patcomm rig which I find the built in keyer impossible to use, but the keyer in the Ten-Tec Argo V is no problem.
