Bob (GM4CAQ) wrote : and no audio level control on the sidetone!. Bob .. the sidetone level (same as Monitor level for SSB .. useful when using a double-sided headset) can be modified in two different ways. If you got to SETUP/Transmit You will see something labelled Monitor TX AF that is what you want to change. Playing with it this morning I discovered another way to do this that was previously unknown to me. If you transmit a carrier in CW (or hit the TUNE button) The AF control near the upper left of the PSDR display switches to control the Monitor (i.e. Sidetone) level. So as long as you are transmitting a carrier, varying the AF level changes the sidetone volume level. Also note that the DRIVE control behaves in a similar manner. Normally adjusting DRIVE controls the % of RF Power out, but if you adjust this after clicking on TUNE then you are setting the DRIVE level just for TUNE. This is a neat feature that allows you to reduce your output power while tuning your antenna, without messing with normal DRIVE setting. I hope that this helps. Best of luck with your 1500.

Re: [Flexradio] Flex 1500 Newbie problems Xmitwaveshape
Hi Bob-- I'm not sure anyone answered your sidetone volume problem. Simple-- the main audio slider (upper corner area) switches to being the sidetone/monitor audio level slider when you key down. So hold a long key down and adjust the slider using mouse with the other hand hi hi. Works in both sideband and cw. Its in the manual.

Just not nice.. never had this latency before on any analogue rig I have owned. Someone said its been fixed.. either I have not set it up properly or they are not CW operators! Robert : PowerSDR is configured so that it will run on almost any Windows computer but there are some settings that need to be adjusted for CW to work properly on most computers. If you read the Flex-1500 manual section on CW and the Flex-1500 part of the PowerSDR release notes (Page 12) they document quite well the three main things that potentially need to be adjusted in PowerSDR to allow for smooth CW operation on the Flex-1500. (Note that you must STOP PowerSDR to make these changes and then START again to determine how effective the changes are. ) The first thing is adjusting the USB Driver Buffer setting. This is accessed via Setup/General/Options. It is a slider the goes from Conservative on the left to Aggressive on the Right. You want to make it as aggressive as you can without causing drop-outs or distortion in your receive audio. My suggestion is to adjust the slider only one position to the right at the time, exit the SETUP, START PowerSDR and listen to a station for a while to determine if the change in settings is causing an issues with receive audio. Repeat this process over and over until you either get to the most Aggressive Setting (unlikely) or you start to hear audio drop out or significant distortion. At that point back it off one position. Resist the temptation to go to the most aggressive setting first as it may cause PowerSDR to hang up or quit (my experience). The second parameter is the Audio Buffer size. Repeat the same procedure as above (i.e stopping PowerSDR, but this time changing the setting to one smaller then Starting PowerSDR). Setup/Audio Buffer Size - You want this to be the smallest value that doesn't cause drop- outs or distortion on receive. ( i.e. 256 or 128 if possible, but 512 is ok). Setup/DSP Buffer Size, CW RX (should be 2048) only reduce this if necessary to further diminish sidetone delay. Changing this value to a smaller one will have an impact on the performance of the narrower CW RX filters. I wouldn't suggest going any smaller than 1024 otherwise you are diminishing performance of the receiver. Adjusting the above three settings should give you reasonable performance on CW with no noticeable sidetone delay. For anyone only using a Dual core machine, if this isn't enough there are a couple of other tricks that help, but I only suggest trying these as a last resort. SETUP/DISPLAY Refresh Rates Main Display FPS (normally 15, can be reduced to 7 with no ill effects). Reducing this should improve the CW performance as it halves the refresh rate on the Panadaptor display, which is quite CPU intensive. If you are really just running PowerSDR (which is what I suggest on a dual core machine) then you can increase the Process Priority by a notch with no ill effects. SETUP/GENERAL/OPTIONS Process Priority (I don't recommend going with a setting higher than Above Normal or High, the default setting is Normal). One other thing worth mentioning is that if you are using the internal keyer in the Flex-1500, be aware that if you enable Iambic sending it will default to Iambic A. Many people (myself included) learned Iambic B and I couldn't send with Iambic A if my life depended on it. The keyer settings are accessed via Setup/General/DSP . You’ll never get “Ten-Tec QSK” out of a Flex-1500 (it is semi-break in only) but with a few minor adjustments to PowerSDR , running on a suitable computer, you should be able to achieve reasonable break-in performance that is comparable to other QRP rigs such as the Yaesu FT-817. I don't remember offhand where the PowerSDR setting is for Monitor Volume (i.e. Sidetone level). There is one. I would really like to see this show up in the same area of the screen where the CW speed is when in CW mode. Currently this control is hidden away. I am not near my Windows PC at the moment .. but if no one posts a follow up I will let you know what the control is called and where to access it. Cheers Michael VE3WMB / VA2NB P.S, I hope that you get your waveform issues sorted out. ___ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flexradio.com/ Homepage: http://www.flexradio.com/
