Re: [Elecraft] Quick review of the new preamps in KXV3B
It appears that the gain of the Pre-2 has not been factored into the S-meter ABS setting unlike that of the Pre-1. I can understand this being the case with the outboard amps, PR-6 and family. However, given that this function ins now internal maybe it could be taken into account. Regards, Mike VP8NO On 07/06/2015 11:27, Sebastian wrote: A very similar experience here as well.

Re: [Elecraft] Quick review of the new preamps in KXV3B
Mike, We'll take preamp 2's gain into account for SMTR ABS in an upcoming firmware release. We also need to account for the 5/10/15 dB attenuation steps available in the K3S. By the way, the MDS on 12/10/6 meters with preamp 2 engaged is a blistering 145 dBm, typical! Have fun-- Wayne N6KR On Jun 7, 2015, at 7:57 AM, Mike Harris mike.har...@horizon.co.fk wrote: It appears that the gain of the Pre-2 has not been factored into the S-meter ABS setting unlike that of the Pre-1.
