Very good analysis by SM5BSZ. In addition to the points he makes about Flex transmitters, the question he asks about the ARRL reviews seems to raise a serious problem. ARRL has identified key-click problems and certain other transmitter artifacts in their reviews, but this phase noise issue is neve

Thanks Lars. It may be time to try to duplicate some of the measurements made by Leif just to make sure. I do have the same SA he mentions in the article and will try to get to it as soon as I finish up some important projects. Right now I am trying to get my Diesel tractor running again befo

Agree but since I use my 5000 with V/U module and run a kW I need to look into this. I have at least 5-6 locals who also do weak signal work on 2m and 432. Gedas, W8BYA Gallery at http://w8bya.com Light travels faster than sound This is why some people appear bright until you hear them sp

He makes a point. My solution is to use a 5000A on HF with an amplifier that has a high operating Q. ;-) ... and my HP-8568A isn't really "quiet" enough to measure TX noise sidebands, unfortunately. A little more seriously, Even if the current combination of hardware and PowerSDR hasn't im

I came across this interesting article by SM5BSZ who discusses some possible transmitter issues with many radios, including the Flex. It has me a bit concerned. I am wondering if anyone has seen similar data for the Flex 5000? The article may be found here: http://www.sm5bsz.com/dynrange/dubu

It would be even nicer to have a timer function with the recorder so it can launch and close with pre-determined on/off times. Bill AD5EW On Oct 16, 2013, at 1:07 PM, Gedas wrote: > I think it would be a really neat feature to be able to pause an audio > recording. I have to let the recordi

PowerSDR has provides to methods of recording. One is to use the REC PLAY buttons on the radio graphics. It will record and playback the frequency you are recording. There is a Wave tab where one can record audio or IQ. IQ allows one to play back the spectrum monitored. It works very well. Jim

It’s easy to switch transverters from PSDR via DDUtil and a LPT-port. If such a port is not available, switching can be done via the Flexwire ports I2C bus. K3TUF makes an interface: http://www.k3tuf.com/FW.html. I use both solutions to switch transverters via a homebrew switchbox based on two 6-po
