Hi Simon et al:
I made a video to illustrate the difficulty with setting the power level in cw mode with my HL2 build 9, under Windows 10/64.
I am endeavoring to demonstrate that the cw output can indeed be reduced to about a watt as indicated correctly on the power output meter using the OP slider. However, when I pause, the HL2 drops out of transmit, and when I close the key again the power is back up to the full 5 watts.
I am grounding only the tip of the front panel jack using a mercury relay driven by the AEA MM3 keyer. The gateware I am using is 71p1 which is otherwise satisfactory and can be seen here: https://github.com/softerhardware/Hermes-Lite2/tree/master/gateware/bitfiles/testing/20200425_71p1
The p2 version works identically in regard to the cw output level.
The video can be downloaded from my Dropbox at: https://www.dropbox.com/s/xk1posxo3n2pojj/MVI_0001.MOV?dl=0
Sorry to give you more work but I hope this helps.
