Re: [Elecraft] p3 Tap to QSY in Data A mode
Hi Alan Not in PSK D mode as we were running PSK65 so in AFSK A mode So if it has an offset programmed in for PSK D mode then maybe AFSK A mode has been an oversight Anyone at Elecraft care to comment, I think AFSK A mode needs an offset of 1500hz in the P3 so you click and tune to the centre of the pass band, as per CW, and PSK D mode.

Re: [Elecraft] p3 Tap to QSY in Data A mode
Hi Jim, AFSK A mode on the K3 assumes you are running FSK. The VFO frequency is the frequency of the mark tone, which is 170 Hz / 2 = 85 Hz from the center of the filter passband.

Re: [Elecraft] p3 Tap to QSY in Data A mode
Jim, I don't have a P3, so cannot comment directly on that aspect, but there seems to be some confusion between DATA A and AFSK A in your latest e-mail, which may obscure your message. The mode normally used for PSK and other sound card digital modes is DATA A. DATA A is an upper sideband mode, and the K3's dial reads the suppressed carrier (BFO) frequency, exactly the same as in USB mode. The centre of the filter passband in DATA A is 1500 Hz above the dial frequency (1500 Hz below in DATA A-REV). If you were referring to DATA A, not AFSK A, your comment about a 1500 Hz offset needed for clicking and tuning to a narrow-band signal like PSK31 could be apropos, i.e. ideally, clicking on a PSK signal trace in the waterfall when the radio was in DATA A mode would tune the radio to a dial frequency that was 1500 Hz below the actual frequency of the signal being clicked on. AFSK A is different from DATA A. In AFSK A and FSK D, the K3's dial frequency displays the RTTY Mark frequency, which is set by the PITCH setting to one of four possible offsets below the suppressed carrier: 915 Hz, 1275 Hz, 1445 Hz or 2125 Hz. The centre of the filter passband in AFSK A is 85 Hz below the K3's dial frequency. If the intent is to tune to an RTTY signal by clicking on the upper (mark) trace in the waterfall, no offset is needed; if the intent is to tune to the signal by clicking halfway between the mark and space traces, then an 85 Hz offset would be needed, i.e. the K3 should be tuned 85 Hz above the actual frequency that was clicked on in order to centre the signal in the passband. 73, Rich VE3KI M0CKE wrote: Not in PSK D mode as we were running PSK65 so in AFSK A mode So if it has an offset programmed in for PSK D mode then maybe AFSK A mode has been an oversight Anyone at Elecraft care to comment, I think AFSK A mode needs an offset of 1500hz in the P3 so you click and tune to the centre of the pass band, as per CW, and PSK D mode. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] p3 Tap to QSY in Data A mode
Why not use your mouse and select signals in the PSK software? You can select any of several signals this way that will be in your passband and it will be right on the signal. You should not be QSYing your radio to tune to different signals in the way you describe. This is just the wrong way to operate PSK. Since the P3 / K3 is not decoding the specific signal you desire to go to, and PSK signals are so narrow, the phenomena you describe should be expected rather than considered a problem. Use the software. 73, Bob W5OV -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of James Balls Sent: Monday, February 07, 2011 5:28 AM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] p3 Tap to QSY in Data A mode Anyone ??

Re: [Elecraft] p3 Tap to QSY in Data A mode
Bob et al, This is not the way I operate in contests, I use the K3's excellent filters! Scenario:- If 1 very strong station is close to 3 weak stations you will not copy the weak stations due to the strong station shutting the ALC down, so narrow the filters right up and hey, there are the weak stations! So using the P3 to find the signals and leaving the K3 filters narrow works real good for me. Only thing i have to do is use the VFO B knob while VFO A is running where I would like the P3 to tune the K3 with click and shoot to the centre of the pass band when in data A mode. I think this is a feature that’s required for the P3. Anyone else agree?

Re: [Elecraft] p3 Tap to QSY in Data A mode
Jim, I thought I saw a post in answer to your comment about QSY in data mode, but perhaps it was an answer in another thread. The poster said he noticed that when he tapped the knob on the P3 he was rotating it very slightly. After seeing this he said he set one of the function buttons to TAP and his troubles went away. I rarely operate anything but CW here and have noticed the same thing happening to me when I'm on a narrow filters setting below 200Hz. Although I haven't done it yet, I plan to make the change the other poster suggested. I hope this has been helpful. 73, Tom Childers Radio Amateur N5GE Licensed since 1976 QCWA Life Member 35102 ARRL Life Member Retired Professional C# Software developer http://www.n5ge.net On Mon, 7 Feb 2011 11:28:11 +, James Balls makid...@hotmail.co.uk wrote: Anyone ??
