Re: BITX40 V2.03 UPGRADE

 

Hi Hiro san,
what resistor value are you using for the CW CARRIER mod?

Originally (in v1), it was recommended to use 10K. But in some cases this
will not give sufficient drive. In that case you need to reduce the
resistor value. In the latest updated instructions, it is recommended to
use 4.7K:



You can experiment even smaller values. But never use less than 1K!

I changed?? software V1.27.3 to??V2.03.
I noticed that??LSB CW output power is slightly down to 3w from 5w than
before.
I tried to ajust BFO freq and VFO??High/Low and so on??for output power up
but I could not.
There is VFO Drive Level control setting??on V1.27.3 but no??V2.03.
All??I need is to modify VFO Drive Level in sketch or driver?? level
volume up in hardware.
Please let me know??how to get?? output power up.
