[Elecraft] Transmit Gain

[Roy Morris]

TX GN in the CONFIG menu first showed Pr80  32.  After re-doing the High Power (50W) TX Gain Calibration the TX GN entry now shows Pr80  35.  This entry updates itself.  Is it possible that a firmware update could affect TX GN?  The TX GN entry in a new kit built K3 that had not been TX Gain calibrated showed 81 without the preceding Pr and without the number in the thirties after the 81.  I don't know the significance of this.  All I know is that I still have low (half the peak power or less) SSB transmit gain.  It takes 28 watts in tune to develop 1 Kw on my Alpha 99 (which has a peak reading meter), and it takes 70 watts to develop this same output on SSB.  I am well aware of the difference between average and peak readings and how they are derived.  The solution to this problem does not lie there.  My Omni VII does not require additional power in the SSB mode to obtain 1 KW after the power has been set for linear tune-up.  I hope this can be corrected in a future firmware upgrade.
