Re: [Elecraft] RE: K3 - should data via the RS232 cable work?
- Original Message - From: Robert Benedict [EMAIL PROTECTED] 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. I recommend a SignaLink USB or the more expensive but excellent Navigator from USInterface.com. You can drive the SignaLink USB so that it keys a radio using VOX, also the SignaLink's soundcard will probably be much better than the soundcard in your laptop. At the moment I am not in a position to add the features you want - as you have a laptop I am sure that you will prefer to use a proper software solution. I used the built-in RTTY in my IC-7800 for about 5 minutes - software programs were much easier to use and offer more modes such as PSK63F, Olivia, MFSK and SSTV.

Hello Dave, It's normal, what you hear ! The direct connection to the d-sub connector is not recomended as it can damage either the computer or the transceiver. You will have to build the interface shown in the N3FJP software, either with transistors or with optical coupling ( prefered, no groud loop!). The result should be very nice with either interface.

[Elecraft] K2/100 Low output pwr 20m and up
Hi all Yesterday I discovered a problem with my K2/100 (Serial 0413). I am getting around 90 watts out on 80 through 30m but the pwr drops down to 50w on 20m and keeps dropping to about 34w on 10m. I have a K2/100. It was originally a K2 when I bought it secondhand back in 2004. I upgraded it from ver A to B at that time. Last Christmas I updated the radio adding the 60m/transverter kit K60VX to it and updated the firmware where needed. Over the summer I added the KPA100/KAT100 and the XV144 kits. At the time everything worked and was with in spec when I set it up. After discovering the problem yesterday I took the KPA100 out of circuit and did some tests with the radio at low power. On the LF bands I get about 9 or 10 watts max but when I change to 20m the power drops to 5 watts and them reduces as with the 100w pa in circuit. I put my scope on the input to the K60XV from the band pass filters and then on the output from the K60XV and the levels match what the watt meter is showing me. The radio has the following modules fitted. KSB2 K160RX KNB2 KAF2 K60VX I have taken the KPA100 out of circuit and am still seeing the issue with the base radio so I cant see it being an issue with the KPA100. The base K2 used to produce 15 watts key down. Not having done any faultfinding on the K2 before could someone guide me as to the best place to start.

Dick Dievendorff wrote: I hope to add a more natural data terminal page that doesn't require you to have a Programmer's Reference manual open when you make data mode QSOs. But I'm going to stop well short of competing with MTTY or any of the other data-mode programs that decode with a sound card. I have vacation plans, so this work won't happen until early next year. My program KCommunicate is intended to take advantage of the K3's built in encoding and decoding. Since it can send CW from the keyboard using KY commands there is no reason why it could not also send RTTY or PSK using these commands, though obviously the software would need some changes such as allowing a larger character set to be sent. However there is little advantage in transmitting data via serial port commands if you still need to use the computer sound card to decode it. The current TT1 implementation of sending raw decoded text back to the serial port is unusable by software that also wants frequency, mode, S-meter readings and other information from the radio. Users who have installed the second receiver option may also want software capable of independently displaying two separate decoded data streams. Dave, G4AON, commented that KCommunicate does not seem to work with a K3. That is hardly surprising, as I have not got a K3 to test it with yet. But even if I did, I suspect I still will not be able to get this to work until there is further refinement of the firmware in this area. - Julian, G4ILO K2 s/n: 392 K3 s/n: ???

[Elecraft] K2 - RTTY walk through, connections, and software
I was planning on waiting till next year when the K3 gets here to play with RTTY, but after seeing all the activity this past weekend I am getting the itch. So I am trying to understand what I need to do to get the K2 on RTTY, or if I am better off to wait. Separate from these questions, I do need to re-visit the K2's alignment and filter settings. It could use some attention, as I have learned more since I performed the last ones after the SSB installation. The long term view is that the K3 will become the primary operating / contesting rig, and the K2 will be used as a back-up and to search for other stations / multi's while in the contest. So I need to be cognizant of how much I spend on a K2 only solution at this time. I do understand I need the following; * Computer, soundcard, and software * K2 needs an alignment, and turn on and setting of the RTTY filters * Interface between the computer and the K2 * RTTY software Anything I didn't consider? Currently my resources are a K2, and a deaf computer. So I know I need to put a sound card in the computer. On a side note, I plan to use the K3 for contesting, would I be better off to start looking at the MicroHam products, and plan on migrating that from the K2 to the K3? I am getting more and more into contesting, and I do not currently have a voice keyer, or a way of keying the CW on the K2 from the computer. I have some very nice responses from my CW K2 keying questions in my Keepers folder, so I'm covered there. Just starting to think about larger solutions that solve multiple issues at once. Filter Setup I have never done RTTY, so my search through the Elecraft archive was fruitful, but I didn't quite understand the results. Has anyone done a walk-through on the RTTY setup like currently exist from N0SS and W3FPR for SSB and CW? Don's page describes settings for RTTY with a TNC. I have seen notes in the archive about setting the RTTY mark and space. Being new to this, not sure what I need to do here, but I got the impression that I should set the passband for 1000 if possible, and 800 if not. Then use the RIT to try and tune the signal. Am I barking up the right tree here? Interface = I picked up Don's line out card to get the output for digital modes, but I am not going to have time to get that together, and revisit the alignments, between now and the ARRL RTTY activity in January. There are many quick and easy commercial interfaces, from low cost to quite expensive, but also with increasing capabilities. Once again, because of the ability to migrate it to the K3, and I am thinking about going ahead and investing in the MicroHam, if that meets the needs. Software With RTTY, do they do the logging with the RTTY software? Any recommendations concerning software? I have been using the N3FJP programs for contesting, and logging, but I am starting to use N1MM for contest logging. -- David Wilburn [EMAIL PROTECTED] K4DGW K2 S/N 5982 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Re: KX1 Lid-Tiltstand
A form of protective lid for the KX1 that also acts as a tiltstand is an interesting challenge, Paul. Sitting here enjoying much-needed rain in Sacramento, I see on my KX1 those two panel screws part way down from the top that could be substituted to hold an elongated hinge for attaching a top created from materials purchased from, say, Tap Plastics. Finding and modifying a useful hinge might be the most difficult search. A modified hasp on the front lip could easily secure into the screwhole for the KX1 paddle, and the lid could swing back to make a tiltstand. I also use a different paddle, preferring the Paddlette, and have it mounted snuggly to the right side on a piece of PC board which in turn is secured by a thumbscrew on the base of the KX1. I use a different thumbscrew, since the original would stick out farther than the rubber feet on the base. One doesn't want to modify an Elecraft cabinet, but nothing is harmed by add-ons which don't mar it. Part of the experimenter in this old ham's heart loves trying to solve such challenges.

Re: [Elecraft] K2 External Keying
Dear Dave, You need to use the transistor circuit too. It does 2 things, first it makes the RS232 levels, which are often +12V and -12V, compatible with the K2 (applying -12V to the keying input is probably not a good idea), and second it inverts the keying. I think the inversion is what is giving you the continuous tone which is the sidetone. The incorrect sequence of dots and dashes are then the spaces in the message rather than the dots and dashes. 73 Kevin w9cf I have configured my computer and paddle according to Figure 8-1 on page 92 of my K2 owner's manual.

When I tell the N3FJP software to send a message, the message is heard but it is not the correct sequence of dots and dashes. N3FJP shows a transistor interface in the help section.

Re: [Elecraft] PSK31 on K3
When I transmitted PSK31 on a K2, I increased the audio until the ALC just flickered. The K3 Manual suggests that the mic gain is advanced until 4-7 bars show on the ALC. I thought compression and ALC had to be zero to avoid excessive bandwidth and distortion? Has the K3 got something the K2 hasn't in this respect? In a word, yes. The K3 manual is providing the correct information for use of PSK31 or other modes on the K3: CMP set to 0, and MIC or LINE IN adjusted for 4 to 7 bars of ALC.

[Elecraft] K3 and AM mode: using the DSP bandwidth controls
A few of you have asked how to use and interpret the settings of the receiver's DSP controls when in AM mode (SHIFT/WIDTH and HICUT/LOCUT functions). I'll be improving the associated Owner's Manual section soon, but I thought I'd try to get the word out more quickly. What the DSP controls are adjusting is the final audio passband: what you hear. This is true in all modes, and is immediately reflected in the DSP graphic on the LCD. When you rotate WIDTH and see 2.80, that means that the audio bandwidth is 2.80 kHz. When you rotate SHIFT and see 1.60, that means the center of the audio passband is 1.60 kHz. Of course there isn't just audio filtering in the K3. As you rotate these controls, we internally adjust the 1st and 2nd I.F. passbands optimally to match the audio passband. For example, in SSB mode, if you set WIDTH to 2.80, and have a 2.80 kHz crystal filter, then you have three filters all cascaded at this same bandwidth: a 2.8 kHz 1st-IF crystal filter (centered at 8.215 MHz); a 2.8 kHz 2nd-IF DSP filter (centered at 15 kHz); and finally, a 2.8 kHz DSP audio filter (centered at 1.6 kHz). We do all the math to make this as seamless as possible, selecting the ideal crystal filter as you cut the highs or lows or reduce the audio bandwidth. With this in mind, I can now explain what happens in AM mode, which has to be handled differently. An AM signal is comprised of a carrier and both sidebands. So it's much wider than an SSB signal, and this is why you need a 6-kHz crystal filter for best fidelity. But this filter bandwidth is only required ahead of the AM demodulator, that is, at the first and second I.F.s. After the demodulator, we're back to the audio passband -- what you hear. So, when you rotate the DSP controls in AM mode, even though you'll typically see the 6-kHz filter selected (FL1 on my rig), you won't see 6.00 shown on the LCD. Instead, you'll see the audio bandwidth (2.80, etc.), just like you do in other modes. And this is what makes sense, given that the controls are linked the AF passband. This will be even more apparent when using FM (coming soon!). FM requires a filter around 13 kHz wide. As you can see, having the DSP controls show something like 13.00 when WIDTH is rotated wouldn't be very useful. You'll want to know how they affect what you hear, not the underlying IF filter selection. Note: For now, I suggest that you enable only the 6-kHz crystal filter for AM. A future firmware revision will also properly handle the 2.8 or 2.7 kHz crystal filters when DSP controls are rotated in AM mode. This will be most useful when doing hicut/locut. 73, Wayne N6KR --- http://www.elecraft.com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 and AM mode: using the DSP bandwidth controls
I'm sure my fogginess on this is due to my own understanding deficit, but I would like some more explanation on this in order to compare how the K3 will be used to how I use GC receivers now to listen to AM SWBC in congested bands. I've found the best way to reduce QRM while using a typical dumb AM/SSB GC receiver is to put the carrier in the center of the IF passband, then switch to either USB or LSB mode (with the carrier zero-beat) and listen to either the upper or the lower sideband. That way, if adjacent-channel QRM is worse on the high side, listening only to the lower sideband eliminates it, and vice-versa. Will something equivalent to this mode of reception be possible on the K3? Bill / W5WVO wayne burdick wrote: A few of you have asked how to use and interpret the settings of the receiver's DSP controls when in AM mode (SHIFT/WIDTH and HICUT/LOCUT functions). I'll be improving the associated Owner's Manual section soon, but I thought I'd try to get the word out more quickly. What the DSP controls are adjusting is the final audio passband: what you hear. This is true in all modes, and is immediately reflected in the DSP graphic on the LCD. When you rotate WIDTH and see 2.80, that means that the audio bandwidth is 2.80 kHz. When you rotate SHIFT and see 1.60, that means the center of the audio passband is 1.60 kHz. Of course there isn't just audio filtering in the K3. As you rotate these controls, we internally adjust the 1st and 2nd I.F. passbands optimally to match the audio passband. For example, in SSB mode, if you set WIDTH to 2.80, and have a 2.80 kHz crystal filter, then you have three filters all cascaded at this same bandwidth: a 2.8 kHz 1st-IF crystal filter (centered at 8.215 MHz); a 2.8 kHz 2nd-IF DSP filter (centered at 15 kHz); and finally, a 2.8 kHz DSP audio filter (centered at 1.6 kHz). We do all the math to make this as seamless as possible, selecting the ideal crystal filter as you cut the highs or lows or reduce the audio bandwidth. With this in mind, I can now explain what happens in AM mode, which has to be handled differently. An AM signal is comprised of a carrier and both sidebands. So it's much wider than an SSB signal, and this is why you need a 6-kHz crystal filter for best fidelity. But this filter bandwidth is only required ahead of the AM demodulator, that is, at the first and second I.F.s. After the demodulator, we're back to the audio passband -- what you hear. So, when you rotate the DSP controls in AM mode, even though you'll typically see the 6-kHz filter selected (FL1 on my rig), you won't see 6.00 shown on the LCD. Instead, you'll see the audio bandwidth (2.80, etc.), just like you do in other modes. And this is what makes sense, given that the controls are linked the AF passband. This will be even more apparent when using FM (coming soon!). FM requires a filter around 13 kHz wide. As you can see, having the DSP controls show something like 13.00 when WIDTH is rotated wouldn't be very useful.

Re: [Elecraft] K3 and AM mode: using the DSP bandwidth controls
To clarify -- Will something equivalent to this mode be possible on the K3 IN AM MODE -- i.e., without having to absorb the carrier energy, as when listening in USB/LSB mode?

[Elecraft]: Tokyo Hy Power HL-1.5Kfx
Has anyone on the list tried running a K2 with a Tokyo Hy Power HL-1.5Kfx amplifier, using full QSK. Is any external hardware required to enable full QSK operation? I got to play with the HL-1.5kFX for a review I did for CQ Magazine. It sources only a milliamp or two, so any transceiver solid-state output will work with it (even my IC-706MKIIG). I measured the QSK relay switching time at about 5ms, but the relays are spec'd at 10ms maximum, 5ms typical. So if you can set your amp enable to RF output delay to 10ms or greater, you won't have any problems. You can start with 5ms and listen on a separate receiver to your signal. You can hear when you start hot-switching your transceiver (sounds like bad key-clicks). Drive the amp with maybe 10-watts or so when you are doing this.

Replacing the diodes usually cures that behavior. 73, Don W3FPR Fred Jensen wrote: DIFFERENT SUBJECT: My KAT100 seems to have lost it's tuning brains. Is there something I can do to reboot it?

Fw: [Elecraft] KAT100 bad behavior
What do we do when we are not using our equipment ? WHY we unplug them from the power lines and we also remove any and all antennas don't WE ! Remember the word ... the word is EMP !

Either you have a really bad load on the KAT100 (like a short or open circuit), or the 1N5711 diodes have been zapped by a static surge of some type (like lightning). Replacing the diodes usually cures that behavior. 73, Don W3FPR Fred Jensen wrote: DIFFERENT SUBJECT: My KAT100 seems to have lost it's tuning brains. Is there something I can do to reboot it?

David, Congratulations! I know you are a Macintosh user (and Cab-converter user!) so I hope you'll also relate your experience with the MacLoggerDX integration and the results from your first contest. I can't wait to work you on the air with your new toy! Take care. Enjoy the assembly process (and feel better!) 73! -- Scott (NE1RD) Mr Brown knew I was waiting for this, he paused to let me take a photo :) Inventory tonight, but real bad cold, so need to feel better before assy. --snip-- 73 de M0XDF FISTS #12575 -- View this message in context: http://www.nabble.com/-K3--SN-174-arrived-at-11%3A45z-today-tp14374951p14381939.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Re: K3 and AM mode: using the DSP bandwidth controls
Bill W5WVO wrote: To clarify -- Will something equivalent to this mode be possible on the K3 IN AM MODE -- i.e., without having to absorb the carrier energy, as when listening in USB/LSB mode? Can I shift the IF passband in AM mode and listen to just one sideband or the other? Bill, In AM mode, if you tap XFIL to select a 2.8 or 2.7 kHz filter, then SHIFT the passband down (counterclockwise), you'll be removing one sideband. The narrower crystal filter passband results in a loss of fidelity from the high-precision I-Q AM demodulator, but the signal will still be intelligible. If you want to control which sideband you remove, you can always use LSB or USB. This provides excellent fidelity on AM signals, and you don't have to touch the VFO -- just changes modes. 73, Wayne N6KR --- http://www.elecraft.com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
