Re: [Elecraft] Fixing partially deaf K2.
Bruce Bowman wrote: Just curious... did you ever get this resolved? I'm not certain yet. Since my original message, I have dropped my AGC voltage to 3.98V, re-adjusted L34, and recalibrated the filters using the most recent notes for using Spectograph, and recalibrated the S-meter. When I connected the K2 to an external antenna on Saturday night, the K2 seemed to be hearing some stations in the DX window of 80m about as well my Grundig Satellite 800 shortwave radio (which was just using its built-in whip). The results are promising but I need more time to listen to stations and compare to my shortwave receivers. While turning the slug of L34 clockwise, the internal signal peaks. Turning it a bit more and the noise to the right of the internal signal begins to drop. About the time it drops the slug appears to bottom out. I am wonders if I may need to change a cap around L34 to bring the point of best S/N ratio to somewhere more in the middle of the slugs travel range. I didn't get any response to whether 2.5V rms on TP1 when the rig is tuned to 80m is withing the expected range or not. For now, I will just have to assume it is. I still think I am getting more of a change in audio level between AGC on and off than I should. To see if the 8V regulator output is causing the problem may require replacing the regulator. I'm not yet sure what voltages/parts I should check in the IF amp or AGC circuit to determine if there is a problem with one of these circuits. Now that the receiver seems to be performing a little better, I will move on to the transmitter. I want to retest the amount of maximum RF I can get from the radio on the various bands and see if the change in VCO output has made any noticeable change. I will also be rewiring T1 and T3 as I don't think they are wound as well as they could be. They could be the cause for the slightly lower RF output (barely 10W) on 10m. -- Cheers!

I would except I probably don't have the right resistor values. The Cheap 'N Dirty signal tracing from N0SS hasn't turned up any noticeable change in signal at any of the text points. I do have some crystal oscillator packages which I could use with a pot on the output to do create a signal source. The noise generator and 3-band signal generator Elecraft mini-modules are on my Christmas wish list. I'm hoping to find one or both under the tree this year. If not, I'll have to order them myself. I can't tell much about your AGC threshold, but certainly 4.1 volts is too high - set it no higher than 3.8 volts. The Rev. G manual says to set it to 3.8 during the construction phase. The Rev. C and G manuals both say to set it to 3.6V in the signal tracing section. Messages on the mailing list suggest setting the AGC voltage as high as possible as long as you can still get no noticeable change in audio between AGC on and off. Since my 8V regulator is putting out 8.45V, I have decided to use the experimental formula for setting the AGC voltage so I have set it to 3.98V for now. -- Cheers!

Re: [Elecraft] RE: K3 - should data via the RS232 cable work?
Leigh Thanks for the response. you wrote: I have found a number of confusing issues with the DATA A filters. I report them to k3support, and eventually they will get fixed. (Some have already.) If you have reproduceable cases, you can write down the details and send them in. I turned these in and the "Line In" problem. Elecraft acknowledged digital problems. Communication seems difficult on these issues. The "Line In" got fixed but the rest are waiting for attention. The "CWT kills digital TX" is the only new factoid. In the lates release, it seems you can avoid the 1KHz Fc in DATA A by using low/hi instead of center/width. I don't have any problems with Data Mode A, except that Dual PB stops all receive signals. The 1 KHz problem I see is on INPUT to the line in in AFSK mode. It appears that the mode only accepts audio in at around 1 KHz. On the laptop trigger mode, you might try setting VOX. With RTTY done as AFSK, the duty cycle is 100% and I would think that VOX, if they allow it, would work fine. I have heard incidental reports that VOX works in PSK mode which has a 50% duty cycle for its idle tone, and higher for data. The problem is not in triggering, but in sending FSK RTTY mark and space. FSK D mode seems to be the only mode that can use Dual PB. That mode does not accept audio in. You must either send text with the KY command, key morse code or connect a PC’s I/O line to the “FSK IN” line on the K3’s AUX I/O connector. (If this signal originates from an RS232 port, it will require RS232-to-TTL level conversion.) I was hoping that Simon would add keyboard RTTY in addition to keyboard CW to DM780.

Re: [Elecraft] RE: K3 - should data via the RS232 cable work?
Simon Fair enough. I'm trying to use your program to ease some on the kinderkrankheiten of the K3 software. I've been trying to find a way to use the Dual PB filter for RTTY. I have tried three approaches: 1. Mode: Data, Data Mode: A You can transmit anywhere in the waterfall. Invoking Dual PB results in no receive signal - waterfall goes blank. 2. Mode rev Data, Data Mode: AFSK There is a strange Line In INPUT filter centered at 1000Hz. If you set the PITCH to 915 in the K3 and your digital software, you can get a signal out UNTIL you invoke Dual PB, then no RF out (although you have receive!). BTW - Both modes are fragile. If you leave CWT on from a previous CW mode they also doesn't produce RF. I have seen very inconsistent results which I think are due to unexpected interactions like this. 3. Data Mode: FSK Dual PB works on receive and on send with KY command. Appears to be robust. Since I use a laptop with my rig I have no parallel or RS232 port lines to trigger FSK, hence my request for a RTTY keyboard capability as the only way I see to use Dual PB.

As I understand it, the K3 is supplied with the latest version, available at the time of packaging / shipping. But note that the firmware is still in active development / maintenance, so you will want to update it to get the latest bug fixes and enhancements.

Re: [Elecraft] New K3 F/W - MCU: V 1.49 DSP: V 1.46 NR Improved.AMadded
Hi Joe, Receiving double sideband AM with offset tuning has some unique audio equalization requirements since the low audio frequencies are boosted by 6dB due to the partial remaining sideband. Agreed, but when, for example, trying to fish out weak signals from NA (10kHz steps) between strong EU stations (9kHz channels) on MW, sometimes one does want to shift around the passband. Audio quality is not so important in this case. Many times SSB is better, but sometimes not. At any rate, I personally would prefer to see the bandwidth in terms of RF bandwidth and not AF bandwidth. vy 73 de toby -- DD5FZ (ex 4n6fz, dj7mgq, dg5mgq, dd5fz) K2/10 #885 K2/100 #3248 K3/100 #67 DOK C12, BCC, DL-QRP-AG, JN58td ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

AM is a double sideband mode and requires equal bandwidth above and below the carrier. Thus with a 6 KHz filter, one would be limited to a 3 KHz (or slightly more depending on the filter skirts) maximum audio frequency. > It might become confusing when one wants to shift the filter > to listen mainly to one side band; On a clear channel with > say 4kHz or when avoiding interference with 2kHz. Receiving double sideband AM with offset tuning has some unique audio equalization requirements since the low audio frequencies are boosted by 6dB due to the partial remaining sideband. Lyle, it might be worth considering a higher high cut/wider bandwidth for receive with offset tuning. If I recall, many of the SW broadcasters are using a "compatible" modulation that is essentially USB with a reduced (-6dB) carrier. In fact, it might even be worth considering "compatible AM" (VSB or SSB with reduced carrier) transmit - after all it's only programming . 73, ...

Here in Detroit we are in the middle of a snow storm that could bring up to 12 inches by the end of today so I am enjoying a slow morning with my coffee and some time to daydream. Here is a thought for the Elecraft design engineers - a KX1 with a redesigned case that includes a hard cover to protect the controls and display during transportation. This hard cover could then flip around and serve as a prop to provide a small tilt angle for the rig during use. The KXPD1 paddle would probably need to be reworked to accommodate a tilt but that shouldn't be too difficult. (I use a detached paddle with my KX1.)

[Elecraft] K3 Firmware version at time of shipping.
Geoff The firmware on mine was right up to date to the version released that week. I would recommend you test and align your K3 with the version that it comes with, then once it is fully working you can update it to the latest version from the web. 73 Dave, G4AON K3/100 #80 = Probably a daft question but am I right to assume that the version of firmware supplied as part of a K3 kit purchased from Elecraft is the latest released version existing at the time of shipping the kit, or is the kit supplied with some early version of firmware which has to be updated as part of the K3's 'alignment'? 73, Geoff GM4ESD ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Local Demos
Wonder that the K3 looks like in person? Sounds like? Works like? Folks who are willing to show their K3 and those that want a little "Kick the Tires" session can make that known on the K3 fourm at < http://www.zerobeat.net/smf/index.php/topic,119.0.html > 73 - K3HRN ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] RE: K3 - should data via the RS232 cable work?
Hi Bob, There would be some disadvantages to sending the RTTY / PSK via the KY command, I honestly think that an external program such as DigiPan, WinWarbler etc. would be a better option. Displaying the text decoded by K3 is another matter. FWIW I don't really have time to add this now, I am trying to get some new analogue SSTV code working before Christmas. If I can send and receive SSTV then I know that January and most of February will be taken up with the supporting software for SSTV such as picture archives, QSL card templates, fancy drawing software and the like. Maybe next year I'll have a better idea for getting the K3 to send RTTY / PSK, but I'll need to be convinced :-) Simon Brown, HB9DRV - Original Message - From: "Robert Benedict" <[EMAIL PROTECTED]> The FSK data mode works with KY commands but not the PSK data mode. I have used FSK with command macros in Ham Radio Deluxe. The DM780 digital modes program, also from Simon Brown, now also supports keyboard CW on the K3. Maybe with a little lobbying Simon will support keyboard RTTY and PSK for the K3. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
