?BITX keyer pull up resistor without jack
#ubitx
At this point I have no intention of using my ?BITX for CW.? I understand I still need the pull up resistor between pins 2 and 3 on the Raduino.? I am trying to eliminate as many unnecessary wires as possible.? Couldn't I just connect a 4.7k resistor between the pins without using the jack or am I missing something?

Here's what I ended up doing.? Might be useful for anyone not wanting the keyer jack and an easy way to go back later.? I folded over about 5mm of the bottom of each leg of the 4.7k resistor to bulk them up.? Then i crimped on molex kk terminals on each leg.? I put heat shrink on each leg and then popped the resistor in the digital connector where the wires for pins 2 and 3 previously resided.? After double checking with my DVM I fired her up and it's all good.? I figured it is best to keep the rig as low drag as possible.
