Re: [Elecraft] Fwd: K3 Failed DSP Firmware Download
In the 3 years of running my K3 I can only remember once having to do a forced reload and it was completely straightforward.don't understand the stress this seems to generate. Since moving to a netbook recently I've been rebooting my desktop every time I wanted to do a firmware upload using a hardware serial port; but I do remember in the past uploading through my Microham CW Keyer via Router with minimal fuss (though can't remember the reason for the previous forced upload...!). So when I needed to upgrade from v4.22 a couple of days ago I thought I'd try the Router again and it went without a hitch and saved all the booting up and swapping cables in the spider infested mess at the back of my underdesk PC. Ofcourse I went into the set up on Router and set to 'No Radio' and 'Disable Router Queries'. You can if you wish store these settings under separate profiles for a single click setup. If it doesn't work and you end up with a 'brick' I can always switch on my desktop PC and do a forced upload via rs232 - what's the panic? 73, Stewart Rolfe, GW0ETF Don Wilhelm-4 wrote: Bottom line - don't load firmware through a Microham device and expect good results. 73, Don W3FPR r -- View this message in context: http://elecraft.365791.n2.nabble.com/Fwd-K3-Failed-DSP-Firmware-Download-tp5996916p5999616.html Sent from the [K3] mailing list archive at Nabble.com. __ 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.

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] [Elecfaft K3] Power Cycle
They are complete resets, occurring after MCU, DSP1, DSP2 loads. Note that the K3 goes through exactly the same LED test sequence and timing is the same as a full reset. The only difference between 'normal' and loading resets is that during loading the resets occur during power on. matt W6NIA On Mon, 07 Feb 2011 08:34:17 -0500, you wrote: Everyone, Many times by both the K3 engineers and others it has been stated to recycle the K3 power after doing a firmware upgrade.

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 ??

Re: [Elecraft] REV button behavior and CommCat
For anyone who may be interested, Howard (W6HN) at CommCat has identified that CommCat is seeing the K3 as going offline when the REV button is pushed and held. This offline recognition also occurs intermittently and with no apparent input to the radio's controls. When the error occurs, CommCat reinitializes its connection with the radio, resetting to a baseline with split turned off, accounting for the behavior. So far, we haven't found the reason for this, but the investigation is continuing. The problem does NOT appear to be with the K3, since I've checked the radio with a different logging program and found no problem. If anyone else on the reflector is using CommCat and seeing this behavior, please contact me. More brains may lead to a faster resolution of the issue. When the solution is found, I'll report back.

As long as the Win 7 user does not understand how the OS handles USB devices, there will always be folks tripping over this opaque procedure in Windows.

It is theoretically possible to set the radio type to None and do an update but you can not allow Router or the microHAM keyer to reset (e.g. power must stay on) during the reboot phase. Because of the possibility to turning the radio - any radio - or the microHAM interface into a brick by an improper update (or by buggy software if microHAM were to allow something like the K3 Utility to disable the keyer's normal operation), microHAM simply prohibits any update through the keyer. 73, ...

While all other features and functions of Elecraft's Utility and Memory Editor works fine, the FW download does not. I have a desktop PC with no serial ports only lots of USB. Elecraft sells a very nice serial RS-232 to USB adapter cable with FTDI chip. Using the FTDI driver to define a separate USB port as a COM port works well. I have also used Prolific drivers for converter cables using Prolific protocol without any attention. Both work really well. It will/would be nice to have Elecraft provide a USB port in the radio like some other manufacturers. ICOM for instance - absolutely trouble free and simple. Copy a file to a thumb drive and stick it in the radio's USB jack and press Upload. Also in the case of ICOM's 7800 and 7700, you can plug a USB keyboard in and run RTTY or PSK - from the keyboard. No paddle needed. Anyway - microHAM has excellent software and hardware but as they say, do not attempt to download FW into any radio using an interface with something like microKEYER II.

Re: [Elecraft] Want to Buy a K3
I bought the 1.5 kHz filters instead of the 1.8 kHz filters, and I don't find them particularly difficult to tune even in a contest. The key, of course, is to adjust the Shift down to somewhere between 950 Hz and 1050 Hz. The only problem I've ever had with them is that some voices have such an extreme pitch that it is necessary to adjust the Shift for clarity, but that is rarely necessary. That all being said, I don't think the 1.5 kHz filters provide that much of an advantage for SSB compared with the 1.8 kHz filters. We're talking roofing filters, after all, and generally speaking there are very times that very strong adjacent SSB signals occupy the space between 1.5 kHz and 1.8 kHz AND are clean enough not to spill over into both passbands anyway. I think the great majority of the time the 1.8 kHz filters with a narrower DSP setting would work excellently, and some voices have better intelligibility at 1.8 kHz than they do at 1.5 kHz. If I were buying them again I'd probably go with the 1.8 kHz filters. 73, Dave AB7E I find the 1.5 KHz filter to be too tight (I have a couple).

The K3 Utility does indeed issue a command that causes a reset. However pressing the power button initiates what Wayne calls parameter save where selected parameters (like the VFO frequency) are saved to EEPROM for use after the next start.

During startup the newly restored EEPROM is used to set up RAM versions of config. Restore wouldn't work if EEPROM were written as part of the post-restore reset. To see this at work: turn the VFO to 7.0 MHz, then turn the radio off and on. It should come back at 7.000 MHz. Then turn the VFO to 7.050. Then load firmware. After the firmware reset completes, what VFO setting do you see? That's the EEPROM parameter save at work. If you save and restore config, the current VFO setting us one of those settings.

Re: [Elecraft] Blue Tooth - Freq. response
Very interesting.

The gain increase is constant in the segment. No, the gain is not constant across the segment, it is tapered so that setting two adjacent ranges to the same level creates a flat response across the boundary. In the case of 2125/2295 (traditional high tones) setting the 1600 Hz band at 0 and the 2400 Hz band at +10 dB will create a measurable tilt between the two tones ... a similar tilt will be seen with the 915/1085 Hz tone pair for the 800/1600 Hz bands. It's easy to see the behavior, simply use a stable oscillator like the XG-2. Set the RxEQ to boost only the 2400 Hz band by +16 dB, zero the dBV meter at 1 KHz and measure the level at 2.125 and 2.295 KHz. The difference will be at least 2 dB (I measure 2.2 to 2.3 dB tilt at both 2125/2295 and 915/1085). The behavior of a parametric EQ (which the K3 is) is very different than a shelving EQ. 73, ...

Right. To understand this, it's important to realize that filters implemented in DSP are simply digital simulations of ordinary analog filters -- in this case, resonant circuits tuned for the desired frequency and bandwidth. Ideally, well-designed sets of filters should combine to yield minimal ripple in their amplitude and phase response if all (or adjacent bands) are set to the same gain. The extent to which this is achieved depends on the circuits that they are simulating, and some circuits are far better than others in this regard. 73, Jim K9YC __ 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

[Elecraft] K2 Kit Questions

So, I wouldn't plan on getting the SSB option and I am not planning on the 100 watt PA or the ATU. But, I do have questions about filters (remember, CW usage only). 1. Question: is the radio a completely analog radio (no DSP) if you DO NOT buy the DSP filter option? 2. Question: is the DSP filter worth the money? 3. Question: is the Audio filter useful? Is the Audio filter still useful if I buy the DSP filter?

Yes, if you do not purchase the DSP option. A substantial amount of digital is still used, but not directly in the signal path. The digital stuff is used to control the rig, set and operate the VFO, change bands, communicate between options, etc. 2. Question: is the DSP filter worth the money? This is a subjective issue. Some people like the DSP (I do), others prefer the simplicity of the audio filter (KAF2). I would recommend one or the other, but the rig runs fine without them. Depends on your operating style. For occasional use, the built in variable bandwidth filter may be enough. I really like the combination of the variable filter and DSP working together. 3. Question: is the Audio filter useful? Is the Audio filter still useful if I buy the DSP filter? See above. Keep in mind that this is a choice of one or the other, not both. The K2 cannot accept both units at once. Any other comments and suggestions are definitely accepted. Buy the KAT2 internal tuner. You won't be sorry. It is astounding in it's ability to match pretty much anything, and will be very helpful if you decide to try out in the field operating with makeshift antennas. - Jim,m KL7CC 73, phil, K7PEH __ 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 __ 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
[Elecraft] K2 Kit Questions
Hello Phil, My answers to your questions would be: 1. Question: is the radio a completely analog radio (no DSP) if you DO NOT buy the DSP filter option? Yes, completely analog. Even the KDSP2 is the audio stage. 2. Question: is the DSP filter worth the money? Personally I don't think so, the artifact is annoying and no way comparable to K3. IMHO, it is just a primitive DSP as at today technology. 3. Question: is the Audio filter useful? Is the Audio filter still useful if I buy the DSP filter? Yes, you can get KAF2 audio filter cheaply in the second hand market because some elecrafters would like to dispose of theirs when they get the KDSP2. For a price of about USD45 in the second hand market, you can get an audio filter + internal clock, very value for money. Only either KDSP2 or KAF2 can be installed but not both. 73 Johnny VR2XMC __ 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] K2 Kit Questions
Phil, The K2 RF stages are all analog. Any digital signals are for control purposes. The VFO is a PLL/VCO implementation. You will get varied opinions about the KDSP2 vs. the KAF2 for CW use. Some like the DSP, others prefer the KAF2, while others advocate that the variable width IF filter is sufficient. I am in the latter category - I have the KAF2 in mine but seldom use it. Since the KDSP2 and the KAF2 occupy the same physical space inside the K2, only one can be present at a time. If you are considering the use of digital modes, you will want to install the KSB2 even though you do not intend to operate SSB. If you are contemplating portable operation, you will want to include the KAT2 internal tuner. If you have any desires to connect the K2 to a rig control computer application (logger or something more exotic), you will want the KIO2. 73, Don W3FPR On 2/7/2011 7:51 PM, Phil Hystad wrote: Gang, So, I am thinking that another kit is in my future.

[Elecraft] K2 Kit Questions
Yes, KAT2 is a good option because it can tune almost anything. I use KAT2 to tune a 40 ft random wire and PTT at any time I like. K160RX is not expensive. If you order KAT2 + K160RX at the same time, you will save some shipping costs. cheers, Johnny VR2XMC 寄件人﹕ Dave Sergeant d...@davesergeant.com 收件人﹕ Elecraft Reflector Elecraft@mailman.qth.net 傳送日期﹕ 2011/2/8 (二) 2:46:28 PM 主題： Re: [Elecraft] K2 Kit Questions On 7 Feb 2011 at 16:51, Phil Hystad wrote: 2.
