Ed, I use an Acom 2000A that is also a low drive Amp with a Flex 5000A using current software 2.0.16.
I still find the spike there even configuring my audio chain properly and watching the ALC but as Tim mentions it is much improved in the current Beta SDR verses version 1.18. I find driving my Acom at 45 watts on three other rigs I stay just under 1500 watts out; but with the 5000A I must hold the drive back to 22 watts to keep from seeing peak spikes above 1500 watts; However my average is down. 73 de KE4WY Jim __________________________________________________________________ -----Original Message----- From: flexradio-boun...@flex-radio.biz [mailto:flexradio-boun...@flex-radio.biz] On Behalf Of Tim Ellison Sent: Thursday, February 03, 2011 10:38 PM To: Ed Stallman; flexradio@flex-radio.biz Subject: Re: [Flexradio] Anyone using an Alpha 8410 with F5K Older versions of PowerSDR did suffer from some overshoot problems. Those issues have been mostly addressed in the latest 2.0.x beta software. You also have to configure your audio chain properly so that you are not clipping the TX DSP and driving it into an ALC state. -Tim -----Original Message----- From: flexradio-boun...@flex-radio.biz [mailto:flexradio-boun...@flex-radio.biz] On Behalf Of Ed Stallman Sent: Thursday, February 03, 2011 9:35 PM To: flexradio@flex-radio.biz Subject: [Flexradio] Anyone using an Alpha 8410 with F5K Before I buy the Alpha 8410, I would like to hear from those using one with the Flex 5000A ... I found a post stating that the F5k would have audio spikes and trip the fault on the 8410 ?
