[Flexradio] Now this is wierd!
I have been chasing some RFI here that appears every 56.746 KHz (Average from 35 samples) over the entire spectrum from 80M up thru 10M. The source is still un-identified after weeks of searching. It is there 24 hours a day, 7 days a week and ALWAYS is on the frequency of that rare one! This morning I found the signal on 5.MHz WWV, just to the high side of WWV. The wierd thing is that every time WWV clicked off a second, there was a pulse that ran from WWV down frequency to 4.962812 where it literally dropped out like it disappeared down a drain. The pulse was about 1KHz wide, almost flat across the top, similar to a square wave. The pulse was -90dBm, 30dB above the noise level. WWV is above -60dBm here. My first thought was, What the H--- was that??? Back to analyzing the interference. It is becoming an obsession 73 Jim, W4ATK ___ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://www.mail-archive.com/flexradio%40flex-radio.biz/ FlexRadio Knowledge Base: http://kb.flex-radio.com/ FlexRadio Homepage: http://www.flex-radio.com/

Re: [Flexradio] 1.10.3 RTTY confusion
As of right now, I am thoroughly broken on RTTY. I think it is because we implemented some fixes to make RTTY contesters happy. 1.10.2 worked fairly well, but actually was partly broken for PSK. I didn't run it long enough to sort it all out, but I could make it work without too much fuss. The main issue for me is that I'm happy, more or less, with MixW, but for normal (non-contest) operation, I have to do a couple of strange things (always have) to make it work. The thing is, MixW is not very smart about offsets (this is true, so far as I could ever tell, for both MixW 2.16 and the current 2.18). If you use the standard RTTY AFSK offsets and then switch to CW, it doesn't appear to remember it should have different offsets for different modes and uses the AFSK ones for CW. I think this is a bug, but there you go, its the world of closed source. A 2K offset for CW is totally hosed. One quickly tires of going into MixW to manually fix things, which as a practical matter simply must be done to do click-tuning or anything else, really. So, for the sometime RTTY user, force-fitting the AFSK offset to agree with your CW listening offset is a pragmatic solution. It's how I get by. (Long time readers might remember I've discussed this before and even advocated it for others). And, as well, for ordinary DX chasing, it is convenient (even if nonstandard) to use USB rather than LSB because both the SDR panadapter and the MixW waterfall work much more sensibly for listening up. So far, so normal, more or less. To recap, I have Mix W set up for a mark/space offset of 400. I have it using USB (logically inverted, but it is explicitly USB as far as MixW is concerned and MixW seems to do the inversion for you if you set it that way -- you can set inverted separately for anyone who really is running USB). I've been able to run it that way since PowerSDR 1.3.something or other. With 1.10.3, it appears that our various fixes for RTTY contesters has broken me so thoroughly, I'm not totally sure I can explain it. What it appears to be is that _even in DIGU_, I get a fixed, negative, standard AFSK offset. Changing the click/tune offset does nothing. I can't find any other control for this. This just totall hoses MixW. When I change from USB to DIGU, the transmitter frequency of the SDR does not change. HOWEVER, MixW seems to be told by PowerSDR that the frequency is something other than it is (about 2K lower, apparently the standard AFSK offsets) and, worse, it actually seems to be listening there. The MixW waterfall and the SDR panadapter are totally mismatched. So, it's not like they disagree about what to call the frequency. MixW really appears to be somewhere else. I can't listen to what I should be. It's early morning as I type this and I was trying to follow a ZL7 pileup, so not much else on. But, as far as I can make out, that's what's actually happening. Worse, I can't simply back up to 1.10.2 because I upgraded firmware. I don't know if going back is a good idea and I don't know what level to download myself to do so (remember that chart I asked for? Having the code paternalistically tell me isn't a perfect solution after all -- and having the download have a name like current isn't keen either for going back). At the moment, I have no plans to go back. I can make it all work, as an SWL maybe, like it used to simply by being in USB. But, the whole point of DIGx was to not have compression et. al. operational for transmit. I didn't submit this as a bugfix, because I have a feeling the answer is working as designed except maybe for the fixed negative offset in DIGU. But, I'm not sure this is the right offset for PSK or other digital modes either. The click/tune had a compromise of sorts by having a different value for upper and lower. But that covers _maybe_ two modes and only applies to click-tune from the SDR itself and not to operations from 3rd party software. It looks to me like you need a digital offset right next to (or, probably, in place of) the click/tune offset, which affects none of this (probably shouldn't). It probably needs to be a drop down with values for known modes that can also be set manually, like the parallel port address setting for SDR 1000 was. Another option would be to have a RTTY profile for USB that did what DIGU/DIGL is intended to do, but runs the offsets naked without any attempt to be smart about correcting to mark/space. Or, perhaps, we need to think hard about giving up on the possibly false ideal of using mark for the apparent frequency to start with (it's potentially a false ideal if you need a different offset for each mode). I'm not sure what to do. All I know is that for the moment, I'm basically not running RTTY with my new rig. Larry Wo0Z PS, now that I think about it, maybe we should use the transmitter profile as the overall solution. We could have the ones we now have for

Re: [Flexradio] 1.10.3 RTTY confusion
Larry, Open the Setup menu on PowerSDR. Go to CAT control. Click on the box that says DigiU/L returns LSB/USB. This undoes the RTTY digi mode fix. And while I am on the subject, a real implementation of FSK and FSK-R is desperately needed in addition to the ASFK (USB/LSB) digital modes is needed to dispel this on going confusion regarding just about every digital mode and RTTY (the odd man out, IMHO). -Tim -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Larry Loen Sent: Thursday, October 18, 2007 8:20 AM To: flexradio@flex-radio.biz Subject: Re: [Flexradio] 1.10.3 RTTY confusion As of right now, I am thoroughly broken on RTTY.

[Flexradio] antenna switching question
I operate the Antenna Selection is 'Expert' mode This way it switches my antennas automatically from antenna port 1 (HF Yagi/Dipoles) to antenna port 3 (6meter Halo) when I select bands from the PWSDR Mode buttons. But what I am seeing is: I set the Antenna Selector to enable the TX1 switch to key my amplifier when in HF modes. If I then go to 6 meter it turns off those Switch Relay boxes (clears the check mark-disables) But when I return to HF from 6 meters, it does not re-enable the relay TX1-3.

[Flexradio] I need help .... please try this.
I need your assistance. I noticed what I think is a problem with my 1 yr old SDR 1000 that I never noticed before. It was actually brought to my attention by another ham. I hear a continuous tone off my main frequency (displaced equivalent of my sidetone). I have sent the rig back to the mothership and they can find nothing wrong. Since this also happens with my Presonus unplugged from the SDR, it must be coming from the SDR unit itself. Also happens w/ Delta 44 snd card. (Don't do the test w/ the snd card unplugged from unit.) It is easiest to hear if I do the following: Try this with your SDR 1000 or SDR 5000 (to see if any difference). PowerSDR version 1.10.1 or later. Set SDR in CWL or CWU Set break in delay to 5000 msec Connect SDR to dummy load Tune your signal in on a 2nd separate RCVR. Set your power on SDR now to Zero. Send a dit on the SDR. I hear a tone that remains on for as long as my breakin delay is set for? In this case for 5 sec after the dit stops. It actually moves the needle on my SWR meter (not the SDR meter). In a conversation w/ the good folks in Austin, they suggested that I ask if anybody else experiences the same thing. So I am. Let me know what you get.
