We have touched all important stages of Ham Band Transmitters and Receivers. One thing we left untouched was the electronic keyer. Serious CW operators know that a paddle is the way to make CW easy and fun. Building one for oneself also is not a difficult task except it requires careful soldering and IC mounting. The electronic keyer is configured in such a way the moment one touches the paddle the entire system changes over to transmission. The speed of a keyer also can be set. Those contact problems with Morse keys are also do not affect the performance of a electronic keyer. The pad contacts at the electronic keyer requires no pressure at all. In C-32/1 see the circuit of an electronic keyer.
In my experience all those who do SSB transceivers builds keyers too. If I share my personal experience insisting on quality components and beginning a project with all god quality components arranged will save you a lot of time and money. Still failures and repeated efforts are not uncommon. There could not be a Ham home brewer who would not have done at least fifty mistakes. This comment goes to one of the best home brewers in India - Late OM TP Guhan Menon VU2TG. In short every Ham had stories of difficulties to share.
Working an equipment developed by oneself from bottom is a matter of great pleasure for all Amateurs. The equipment should be compact, portable, operational in battery, sensitive to weak signals, powerful and easy to operate .... individual specifications vary. The truth is that there are Hams who could reach this state of affairs too, though with difficulties. What we were discussing through all those previous chapters was guidelines that could take anyone to such a level of craftsmanship. If this Book could be of any help to the readers the efforts behind this is justified.
