[Elecraft] RTTY via FSK-D
So I'm thinking about wiring up the FSK IN pin on the AUX connector to do RTTY TX properly. I'm curious of a few things before I take the time to make the cable. First off how do people usually drive this signal? I assume its usually taken off of a serial port... I've tried a few RTTY apps and I've gotten them all to work via AFSK and all seem to have their pros/cons. I have a feeling in the end that I'll probably most use MMTTY being that it has a very nice interface into N1MM (unless there is another application that has a nice interface into N1MM that I should be aware of). Finally my last question is that if this comes off of a UART how has the timing been for people? I remember a while back I used a UART to to CW keying in N1MM. I remember being embarrassed by the CW that was sent and I've since bought a K1EL WKUSB kit and put that together... Very happy with that little box. Would I have these same timing issues in this FSK_IN setup? If there was ever a stupid thing is trying to use Windows as an RTOS. ;) Anyway thoughts appreciated. ~Brett (KC7OTG) __ 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] xv144
Hi there, Got the xv144 yesterday. Built it in in one hour. No problems, works as promised.. Very clean SSB and FM signal. The only thing: I cant get a 1750 herz tone as stated in the manual..

[Elecraft] OT: FCC seeks comments on blanket amateur radio waiver for disaster drills
http://hraunfoss.fcc.gov/edocs_public/attachmatch/DA-10-365A1.pdf The Federal Communications Commission is accepting comments through April 2 on an AHA request for a blanket waiver to permit hospitals seeking accreditation from The Joint Commission to use amateur radio operators who are hospital employees to transmit communications on behalf of the hospital as part of emergency preparedness drills. Hospitals accredited by The Joint Commission must prepare an emergency operations plan setting forth how the hospital will communicate during emergencies, establish back-up communications links to communicate essential information if primary communication systems fail, and test their emergency operations plans twice annually. The AHA requested the blanket waiver last month as an interim solution to prevent the FCC and hospitals from having to prepare, file and process a raft of waiver requests while the FCC prepares a proposed rule that would allow amateur radio operators who are hospital employees to participate in drills. de Doug KR2Q Tnx for the BW __ 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] K3 #3934 live and running
George, It really depends on the type of noise. The various outboard DSP units are quite helpful improving selectivity of older radios, clarity by reducing some background noise, etc. I don't recall them being effective with impulse and/or broadband noise typically associated with things like powerlines, mercury or sodium vapor lights, etc. On occasion you may find a rig's noise blanker can help, but unfortunately few NBs perform well. Some years ago out of the blue I got hit with S9+ noise across all bands almost 24 hrs a day. Powerlines are underground. Spent days tracking it. Then one day while raking leaves I noticed my neighbor's sodium vapor floodlights were flickering...a symptom the lights were on their last legs, but long legs since it took months for them to finally go kaput. I purchased a Timewave ANC-4 unit and installed a noise sensing antenna. With time and patience to experiment with antenna placement and the ANC-4 settings I was able to get the noise from S9+ to S2. But again, it took a lot of time and patience to get there and it worked for that particular type of noise...may not work for others. I seem to recall a link somewhere on the ARRL website that takes you to a page where various noise samples are recorded. This may be a good place to start so you can get a sense of a particular noise source that may be causing much of your grief.

[Elecraft] RTTY questions
I am having trouble getting started in RTTY. Am using AFSK and N1MM with MTTY. In the RTTY Engine it appears that I am transmitting, but there is no output. Last night I went through all the K3 config parameters, and still no luck. There were a few times that I noticed an Overload error message...Another thing is that in the TX tab of the setup, it will not recognize my COM port. Thats probably because it is in use. The problem may be a N1MM setup issue. In the Configur Ports tab, what ports do I need to assign in addition to the radio?

Re: [Elecraft] xv144
In FM mode, hold PITCH and set VFO A to 1750 Hz, and VFO B to TONE ON. The K3 will display FM T When you transmit, the 1750 Hz tone will be sent every time for about a second. I just tested it here and verified it is working. 73, Lyle KK7P __ 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] RTTY via FSK-D
Brett, Regarding the timing problems you had with CW from a serial port: In this situation the timing is not done by the UART, it is done directly by the CPU toggling the control line (usually DTR) on and off, and is therefore subject to non-RTOS timing problems. If you are using a UART to do FSK on its standard TxD data output, the timing is controlled by the clock in the UART, so the timing issues that affect serial port CW do not affect FSK done in this way. In a sense, the UART for FSK is a logical equivalent to the Winkeyer chip for CW. However, this only applies if the UART is capable of doing 5-bit codes at 45.45 baud. The UARTs used in PC serial ports have this capability, but most USB-to-serial adapters do not. One giveaway is the maximum speed supported by the adapter; if it is greater than 230 kb/sec, then the minimum speed is too high for RTTY. Currently available single USB-to-serial adapters are too fast for RTTY, but some 4-port or 8-port USB adapters can handle the slower speed. There is an add-in for MMTTY called EXTFSK that is capable of doing 45.45 baud RTTY with any USB-to-serial adapter. EXTFSK can key any of the TxD, DTR or RTS signal lines on any serial port or serial adapter; in fact, it can even do FSK keying via a parallel port. The downside is that the timing is handled by the CPU, not by the UART. However, apparently EXTFSK uses the same sound card timer that is used for AFSK, so the timing of EXTFSK-sent FSK should be the same as the timing of sound card AFSK, no better and no worse. You do need a keying circuit between the serial port and the K3's FSK input. The same kind of one-transistor or opto-isolator circuit that is usually used for serial port CW or PTT will also work for FSK keying. 73, Rich VE3KI KC7OTG wrote: So I'm thinking about wiring up the FSK IN pin on the AUX connector to do RTTY TX properly.

[Elecraft] OT: RFI from Modern Furnaces
Hi all, There was a discussion some time ago about RFI emanating from front loading washers. This note is about the possibility of RFI emanating from microprocessor controlled house furnaces. We had to have our house furnace replaced last week because of a failure. Yes we winter camped for a over a day as a result. We now have a 95 percent efficient microprocessor controlled furnace installed. I did not think about possible RFI that it might emit at the time of choosing that furnace. The good news is that I have not found any RFI on the HF bands as yet while the furnace is active or not active. My question to the group is: was I lucky? The furnace control has a very nontrivial computer control and could cause plenty of noise. It would be nice to think that the designers of furnace control systems are sensitive to RFI radiation issues. The furnace is a Lennox model G71MPP.

I'm not sure I understand what you're saying. Your HC-4 should connect to the sound card MIC IN (via STEREO plug with audio on tip, shield on shell, no connection to ring). Turn sound card MIC BOOST on. The sound card output (tip or ring of 1/8 stereo) should connect to LINE IN on the K3 (1/8 mono).

Re: [Elecraft] K3 Stereo mic plug into rear panel mic (mono) jack! Okor not? PTT or VOX during SSB contest?
HC-4 is plugged into the sound card MIC IN, straight connection, no adapter. It works fine, can record and audio is good. The sound card output was connected to the K3 MIC MONO on the rear panel, with rP.H selected in config. I did this based on N1MM setup information. I used a stock 1/8 stereo cable. I did not try LINE IN MONO on the rear of the K3. I did get it to work by going from sound card out to the K3 front panel mic connector using the Heil adapter. It was set at FP.H. It worked OK. If I understand correctly, I need to have an stereo to mono adapter and use the K3 LINE IN MONO. Is that correct? Thanks for your help Dave!

Re: [Elecraft] RTTY via FSK-D
MMTTY used to send upside down in FSK and there was no way to change it via software. MMTTY does not send upside down. It generates a 1 (high) on the output of the UART for mark which is correct. Most interfaces use a simple NPN transistor which turns that 1 into a closed contact (again correct for the old 60 mA loop circuits). Unfortunately, many rigs expect the FSK input to be OPEN (or high due to their internal pull-up) for Mark. The user needs to read his transceiver manual and if it is normally mark open or mark High, select REV in the menu ... this applies to such a diverse group of transceivers as the FT-1000D, FT-1000MP, IC-706mkIIg, TS-870, etc. Again, MMTTY is not upside down ... it is the interface standards that are still rooted in the 60 mA current loop instead of the data communications world where Mark=1/Space=0. 73, ...

Re: [Elecraft] A K2 question - checking the amp
Hi Dan, You might check the DC bias voltage on the current sense resistor near U7A. I would guess that it would be higher when the K2 Power is set above 10 watts then when it is set below. This shift might represent Emitter current acting somewhat normal. Perhaps check the voltage difference between pin 6 of U7B and each base of the 2879s. These should not be too different from each other. I might check the resistance between pin 6 of u7B to GND and compare that to the 2879s Base to GND resistance. It should be a little more as you are adding in the bias resistors. Even with the 2879s in circuit I would try using my diode check on the 2879s emitter-base junctions, for the possiblity they can be read that way. At a time like this, one would surely like to have a schematic marked up with the good-known test voltages marked on it! Hope this helps, N1BBR ?Hello all, Is there a way to check the PA transisters in my K2 safely while still installed? Thanks in advance.

Re: [Elecraft] RTTY via FSK-D
The Invert logic option in MMTTY only applies to PTT. The UART's FSK output cannot be inverted. If you are using EXTFSK, there is an option to invert the FSK logic in EXTFSK. This is immaterial with a K3, though; all you have to do is adjust CONFIG:FSK POL (set it = 1 for normal polarity). 73, Rich VE3KI W6SX wrote: I've never had occasion to use it and maybe I misunderstand what it is supposed to do, but it looks as if one can switch MMTTY transmit logic as follows: Open MMTTY Option Setup MMTTY TX Check or uncheck Invert Logic __ 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] K3DSP Upgrade Board
FYI - I ordered the K3DSPUPGD board to update my K3. I ordered it Jan 10. Had no word, but the 3-4 weeks on the shipping status page on the Elecraft web site had passed by twice. So, last Friday I called and talked to Lisa. She said it would be 3 more weeks, anyway. But she suggested an alternative that worked out well - send my board in for modification. Mailed it from Maine last Friday. They got it Monday. Modified it Tuesday. Shipped it back Tuesday. Arrived in Maine on Thursday. In the radio and back in operation on Thursday. At 6 days door to door across country, it's a great option. Most everyone can live with the backup rig for less than a week. 73 de K1ESE John __ 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] RTTY via FSK-D
First off how do people usually drive this signal? I assume its usually taken off of a serial port... I've tried a few RTTY apps and I've gotten them all to work via AFSK and all seem to have their pros/cons. The most common way, and compatible with most loggers and RTTY software, is to drive the K3 FSK and PTT lines on the AUX connecter from a serial COM port on the PC. All that's needed is a level shifter from the PC RS-232 to the K3 TTL. Use a 1-2Kohm base resistor and an NPN switching transistor in the FSK and PTT lines. A diagram of this (except for the K3 AUX connector pins which is in the K3 manual) can be found many places, including www.rttycontesting.com. I have a feeling in the end that I'll probably most use MMTTY being that it has a very nice interface into N1MM (unless there is another application that has a nice interface into N1MM that I should be aware of). In the recent RTTY Contesting Survey just completed, 75% of the respondents use MMTTY. Look no further. It is beautifully integrated with N1MM Logger. Finally my last question is that if this comes off of a UART how has the timing been for people? I remember a while back I used a UART to to CW keying in N1MM. I remember being embarrassed by the CW that was sent and I've since bought a K1EL WKUSB kit and put that together... Very happy with that little box. Would I have these same timing issues in this FSK_IN setup? If there was ever a stupid thing is trying to use Windows as an RTOS. ;) Timing is perfect. I've never heard of a problem, especially because of the UART in the PC.

I built a separate relay into my interface that disconnects the microphone when the computer is operational sending a SSB message, and the mic is activated and the computer message is stopped as soon as I put down the footswitch to manually operate the mic. I can't imagine trying to use the computer during a SSB contest or for meteor scatter without the ability to interrupt it. The programs I have used for this look for an interrupt via the serial port's DSR line. I would think this would be possible with a flexible rig such as the K3, but apparently it is not yet incorporated into the firmware. I don't know if it is on a firmware wish list or not, but I think it should be. GL and VY 73, Lance -- Lance Collister, W7GJ (ex: WN3GPL, WA3GPL, WA1JXN, WA1JXN/C6A, ZF2OC/ZF8, E51SIX) P.O.
