I have seen this as well with version 2.0.19. I generally run at 79% Drive level with ALL previous versions of PowerSDR but with PowerSDR 2.0.19 I have to reduce the drive clear down to 47% for the exact same output power level to drive the AMP at 75 Watts on voice peaks. With out the FLEX having ALC it is very important that the Drive level does not over shoot above the set level. In the past there was ALWAYS the peace of mind that the Maximum output would stay where your TUNE Drive was set, even When my radio is set @ 100% on 40 meters my radio puts out 147 Watts on my calibrated "WAVE NODE" Power Meter even after a Database Reset. SO just be careful and check your Voice Peaks with a Peak reading Watt meter so you don't smoke your amp and hope this is fixed soon. 73's Bret WX7Y -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Neal Campbell Sent: Wednesday, March 02, 2011 3:04 PM To: Steve Tripp (K1IIG-1) Cc: [email protected] Subject: Re: [Flexradio] FLEX5K Drops Amplifier I can attest to Steve's credibility and observation. I have not had my 2000a on line for 6+ months and just hooked everything back up this weekend. It will trip with 25 watts, cw, psk, etc. I do not know if there is a spike in the key up or key down but I would suspect the latter based on what I see when it trips. 73 On Wed, Mar 2, 2011 at 4:37 PM, Steve Tripp (K1IIG-1) < [email protected]> wrote: > Using my FK5 has frequently causes my Acom2000a to false off.
