Re: [Flexradio] Flex 5000A Elecraft K3 now on the Sherwood
Rob, was there any particular reason the K3 wasn't tested using the available 8-pole 250 Hz roofing filter? I'd be curious to know how much if any this would add to the narrow spaced dynamic performance of the K3 (tested with the 5-pole 200 hz). 73, Kirb - VE6IV -- Rob Sherwood wrote- The SDR-1000 will not be listed since other spurs predominate over 3rd order products. Also as some have commented, the undesired products (spurs, 3rd order, ground loops, etc.) vary so much from one sound-card installation to another to make a data set from one test setup almost meaningless. General comments: Isn't it wonderful that American ham equipment manufacturers are back in the fray. It is no longer only Japan, Inc. There is more to choosing a radio than just numbers. Deciding between running a radio with knobs or a mouse and a computer is a very personal choice. The K3 has knobs, but no band scope. The Flex has an amazing band scope. The loaner K3 in my lab has a rack-sized 85-pound spectrum analyzer hooked up to the IF output. Hopefully Elecraft or other aftermarket solutions will be smaller than this!

[Flexradio] high performance event timer
Steve, some good background on the HPET http://www.microsoft.com/whdc/system/CEC/mm-timer.mspx As far as I can tell this feature is supported only by Intel chipsets. Both of my AMD MB's did not have an HPET setting in the BIOS nor did they indicate as being supported when I ran the test utility (which I can not find). Thus I ditched my AMD hw and went back to an Intel platform (775X chipset). 73, Kirb - VE6IV -- ___ 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/

[Flexradio] v1.10.3 and 1.10.1 CAT/Paddle CW issue
Eric, as of svn1744 here's what I'm seeing here. SDR-1000 K1EL on DTR (no CAT!), key closure. Primary input - com1 = works! Initially got an occasional breakup if I timed it just right, but much improved. Primary input - SDR[iambic] = no joy. Iambic paddles to the back of the radio will give you a MOX/PTT operation on the dit side of the paddle and a proper dash on the other. IF you initially hit a dash the radio will then send dits as well (until the radio drops back into rec.). Secondary Input - Com1 = misfiring Keying on DTR PTT none (running radio break-in enabled) Still experiencing rather frequent breakup and popping on tx sig. Makes no difference if I key the DTR line or switch to RTS.

[Flexradio] PTT Broken
This is likely all related; As of svn 1738 break-in on cw ceases to function unless the VAC button is selected and then de-selected, or the console is powered off/on. The radio works for a short period and then spontaneously quits transmitting (no t/r). Eric's been working on this over the last several svn releases. This problem is present when keying via the PC Com port (ext. keyer), or directly into the key input on the radio. I'm also curious to know others experiences using a paddle plugged directly into the radio's key jack (keying iambic mode) with the last few svn releases? 73, Kirb - VE6IV -- I don't know if anyone else has this problem. If I switch to cw from ssb, or the other way, the ptt or break in do not work. If I stop SDR and restart all comes back ok. As soon as I switch between cw and ssb again it quits. It is very consistent on 160-40m, not so much above 30m. Vox works no matter what happens, but it won't key with the key or ptt. I'm using SVN 1738, I tried an older version like 1730 and it doesn't do this. Is it a bug? or just me.

[Flexradio] Large out of band tx spurs on 5000A

I turned on my 756PRO2 with its spectrum scope and sure enough I have a very strong spur at 5354 kHz when transmitting on 3570 kHz. I haven't tried this test on any other bands yet. I remember 40 meters as being easy to get a low SWR. I hope this a user configuration issue. The frequency is too far away to be a tx image issue.

[Flexradio] problems with cw breakin 10.2 vs 10.3
Bug report filed. Please try Com1 in the interim. as your keyer interface. Kirb - VE6IV -- Hello, I am having a problem using cw breakin with my SDR-1000. I am uncertain whether I have set something up incorrectly or I've stumbled on a software issue. The details are as follows. Using 1.10.2, breakin works very nicely for either of these configurations: a paddle connected directly to the key jack in the back of the unit (with iambic set), or a bug connected in the same way (but without iambic). Breakin delay in both cases is 700 ms. The delay is observed even with a single 'dit', as expected. Keying is smooth. Using 1.10.3, I see something different. A single 'dit' with the bug keys the transmitter but almost always no delay occurs. The transmitter drops right back to receive. Usually a 'dah' works as expected (i.e., with a delay), but not always. Sometimes no delay occurs and other times the delay is much longer than 700 ms. Attempting to send with the bug results in completely unreadable code. In addition, the relay in the SDR-1000 chatters with almost every character. The paddle with 1.10.3 (iambic set) produces the expected delays for single characters except very rarely. However, for reasons that aren't obvious to me, the keying is strange--as if there are extra 'dits' and 'dahs', or the latency is too high. Code can be sent but it is not easy. Does anyone recognize these symptoms as due to inappropriate settings? I always try to maintain the same setup across versions (I use a notebook so that I can reproduce the options on each form carefully). But maybe I've missed something? Has anyone else seen the same thing with 10.2 vs. 10.3?

[Flexradio] CW keyer [primary] input
Still trying to get my head around this. Given the fact (per the manual) that the Primary keyer input takes precedence and overrides any device attached to the Secondary input, one would assume you'd have at least the same level of functionality as is available on the secondary input. I'm referring specifically to accessing the PTT and keying lines (DTR/RTS) as assigned to the DB9. Why do these pins only become active when assigning secondary status to the Com port? For those of us who use the com1 as our only interface it precludes the use of keyer driven/timed PTT and keying sequencing on the port. 73, Kirb - VE6IV ___ 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] Buffer / Sample Rate
Steve, ok, if you go into setup, then: DSPOptions tab . You should have a Buffer Size setting. One value for Receive and one for Transmit. I find that if you run with Receive set to 4096 and then Transmit at a smaller value you have to make sure that each time you start PowerSDR you go in and (re)select the receive buffer value. Otherwise the receive level calibration will be off by 6-8 dB. It would appear that in spite of calibrating against the receive value it subsequently uses the transmit buffer value on each successive re-start. Obviously an beta bug and likely will get fixed once Eric returns from vacation and sees my bug filing. Cheers es 73!

[Flexradio] Buffer / Sample Rate
Ken, I wish I could comment on the F5000 in the config you speak of however I can state that the SDR-1000 runs without issue for me at a DSP buffer setting of 256 and 512 both at 192k. The key for me was two-fold effectively fine-tuning the buffers for smooth operation. First, make sure your running PowerSDR in a above normal process priority setting. I'm not sure what the equivalent setting equates to with the F5000 however the same concept should apply. Secondly, set the DSP buffer and sampling rate parameters *first*, running the receive buffers at 4096 to maintain filter performance while reducing the receive buffers to 256 (cw) or 512. Next, tweak your audio and driver buffers until you find a combination that works well with the DSP buffers/sampling values defined above. As John mentioned, the two (audio and driver buffers) should initially be of the same value. Depending on your PC platform you will want to reduce (or increase) those two values in concert (and then individually) until you have hitless audio and no snapping on tx/rx change-over. My hardware config here is pretty mainstream; Dedicated XP box running a Pentium D dual-core (3.60 Ghz) and 2 MB of RAM. The split DSP buffers (Tx/Rx) is for a cw op, like having your cake and eating it too. In previous implementations of the code, one would have to accept a certain amount of transmit and timing latency to ensure that receiver performance was not impacted too greatly with overly smallish buffers. Cheers 73! Kirb - VE6IV --- Hello and thanks for the replies. However I must be missing something here. I am still running 1.10.2 with XP along with the Flex5000, and I don't see where my question actually had gotten answered. My CPU is a duel 2.4 Intel Processor with 4 gigs of memory. My statement and question was that some people are using 192K sampling rate with 256k for buffering. Are these settings being used in Safe Mode 1 or in Normal Mode? The reason I had asked, I can only run 192k sampling rate at (512k Buffering) When I try to go to 256k buffering, the program crashes. Again, other people were using 192/256 before any new SVNs. How were they able to achieve these settings without any issues? My head is thick, so you have to pound harder!!

[Flexradio] SDR-1000 CW Contest Performance

[Flexradio] SDR-1000 CW Contest Performance
Charles, while I fully understand the intent behind sharpening up the filters for battle in contests etc., I've found that in practice the radio continues to exhibit excellent filter response using DSP buffer and sampling rate settings which, while not absolutely optimized from a filter performance perspective, provide low latency operation equal in feel to my other more traditional radios. For example, your dsp/sampling combo yield an approximate latency of 85 ms! Utilizing the faster sampling rates of the FA-66 (192000), with a sub-optimal dsp buffer size of 2048 equates to a total latency of 10.7 ms. Obviously for me the perfectly in-step key-sync and change-over timing out-weighs the ultimate shape-factor tweak (2048 vs. 4096). Just another reason to like the flexibility built into this box! 73, Kirb - VE6IV -- -- ___ 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 Homepage: http://www.flex-radio.com/ FlexRadio Knowledge Base: http://kb.flex-radio.com/
