Gamaliel,
Your statement is true IF you do not want to get serious with CW.? There are a couple of options that make the ?BITX operate more as most commercial rigs do on CW.? The most significant is that the dial displays the transmit frequency.? The stock will transmit either the sidetone above or below the dial frequency as delivered.
So If you are planning on mostly SSB and only causal CW use, then the stock software is fine.? That is my opinion, others may have a different view.
