In checking out my new Flex5000A transmitter on all bands I noticed that on 6 Meters the transmitter output power would decay from 10 watts to 0 over a period of approximately 6 seconds all other bands were solid.....Tune mode was utilized to generate the RF output and the ATU was bypassed......A dummy load was utilized on ANT3 to eliminate issues with VSWR...... I have identified the cause of this abnormal behavior......In my test set-up the DC power supply used had an output voltage of 14.35 VDC.....Lowering the DC voltage to < 14.0 VDC eliminated the abnormal behavior seen on 6 meters......This transmitter output power decay behavior was not seen on any other band ......Though I don't consider this a design flaw it may be prudent to identify the circuit causing this DC voltage sensitivity....A full DC voltage range/performance test (13.6 VDC +- 10%) may identify other circuit sensitivities ....... Hardware = Flex 5000A Software = PowerSDR 1.10.3 Firmware = 0.1.1.6 Great Rig..... Cheers.... -------------- next part -------------- An HTML attachment was scrubbed...
