Re: [Flexradio] Odd signal while TX using CWX
Don, That did not take care of the problem; you just thought it did. What you & Mario are seeing is the results of a bug that appeared in v2.0.16 when they left the panadapter on during CW transmissions. (See my previous reply to Mario.) The TX filter settings of the currently-selected TX profile have NO effect on the transmitted signal during CW transmission. Notice that the option to change the TX profile is not there in CWU or CWL modes. That is because the TX profile is not used for CW. To prove this, select a "normal" TX profile, let's say "Default DX". Switch to CWU or CWL, send a series of dits (or dahs), and observe your power output on an external power meter. Then create a special TX profile with TX filter settings that do not include 600 Hz. For example, I have a custom TX profile that I use for RTTY. The TX filter settings are 1950 Hz to 2450 Hz. Then switch to CW and again observe the power output when you send a string of dits or dahs. You will see that they are the same. If the TX profile filter settings were active on CW, then the power output should be zero. 73, Ray, K9DUR http://k9dur.info ___ 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/
Re: [Flexradio] Odd signal while TX using CWX
Mario, This is a bug that appeared in v2.0.16. It continues in v2.0.17. It does not affect the functionality in any way, so it probably is way down the priority list. In previous versions, the panadapter display was blank during CW transmission. This was done for processing resource reasons. Starting with v2.0.16, the panadapter is on during CW transmissions, but provides no useful information about the transmitted signal. What is displayed is a band of noise corresponding to the currently-selected profile's TX filter. The TX filter is not used for CW transmission, therefore the current TX filter settings are irrelevant; they do NOT affect the transmitted CW signal. However, they DO affect what is displayed on the panadapter during CW transmission. I believe that the intent is for the panadapter to display the spectrum of the transmitted signal in CW, the same as other modes. The bug is that it fails to do that. 73, Ray, K9DUR http://k9dur.info ___ 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/
[Flexradio] Odd signal while TX using CWX
Mario I found something similiar though I dont recall it being as wide so I just set a xmt filter to narrow the xmt bandwidth and that took care of that problem, though, it would be nice to know what was causing that and if that was really a problem with the radio.

Re: [Flexradio] Odd signal while TX using CWX
Hi David: Thank you for your response. I disconnected all mics from the radio and I still get 3 khz wide constant signal and the CW peak on the TX freq. I guess there is another signal source which I cannot locate. BTW, VAC is off 73´s Mario - Original Message - From: "David Walker" To: "Mario Aviles" Sent: Saturday, January 29, 2011 7:05 PM Subject: Re: [Flexradio] Odd signal while TX using CWX Hi Mario ...And if you talk into your microphone it will appear as though you are modulating SSB. I found that by disconnecting the mic while in CW will stop any movement on the panadaptor while in CW TX mode.
