[Elecraft] K2 KIO2 - Serial to USB

Re: [Elecraft] K2 KIO2 - Serial to USB
You can use a USB to serial adapter but you must make a cable/adapter than connects *only* pins 2,3 and 5. Other pins on the KIO2 connector are not compatible with RS-232 (+/- signal levels). 73, ...

Re: [Elecraft] K2 KIO2 - Serial to USB
You can use a USB to serial converter, but you MUST make a special cable to connect to the K2 that only connects some of the RS232 lines. Look at the K2 manual for info. If you don't do this you can do serious damage to the K2! Vic 4X6GP/K2VCO On Aug 27, 2015, at 4:27 PM, George Rebong ke6t...@gmail.com wrote: My K2 has KIO2 RS232.

Re: [Elecraft] K2 KIO2 - Serial to USB
George, Do not plug the USB to serial adapter directly into the K2 AUX I/O connector, plug the adapter into the special cable made to connect to a computer serial port. The AUX I/O connector contains some non-RS232 signals that are used to control external Elecraft devices (KAT100, KRC2, XV series transverters) and those signal lines will not withstand RS-232 levels - in other words, you can damage the K2. USB to serial adapters differ, even those with the FTDI chip. Some do not like to run at the slow 4800 baud rate of the K2. If one does not work well, try another brand. 73, Don W3FPR On 8/27/2015 9:27 AM, George Rebong wrote: My K2 has KIO2 RS232. Most of the computers now does not have the RS232 DB9 port.

Re: [Elecraft] CW RX
I use similar settings - except I follow the advice of Wayne and Lyle against using any boost in the EQ. That leaves the bottom two and top two bands at -16 with the middle four flat. On occasion, I have also set the 1600 Hz band to -16 dB but I set Pitch at 490 Hz which places 1000 - 12000 Hz well down on the filter skirts even if I have widened the DSP to 800 Hz. 73, ...

Re: [Elecraft] K2 KIO2 - Serial to USB
George, Just in case it isn't quite clear. DO THE SPECIAL CABLE The special cable is what makes the DB9 jack safe to connect to any of the RS232 stuff, including the USB to serial adapter. The special cable, a Y cable, puts the three safe RS232 leads on one side of the Y and the dangerous Elecraft proprietary K2 internal voltages on the other side. If you have no external need for the proprietary voltages, you can just do the RS232 half of the Y to hook up serial stuff. There are useful variants of this You can do, such as the RS232 half of the Y only, with a mini tip ring sleeve stereo plug on the non K2 end. This with a bundled key lead hooks up the K2 to my bitty MicroHam CW Keyer for portable QRP contest operations. The CW Keyer then connects to my laptop with a USB cable, adding all the useful Winkey functions.

Re: [Elecraft] CW RX
It's personal taste, your headphones/speakers, and state of your hearing. My hearing is pretty bad and my hearing aids don't work under headphones [I never use speakers]. CW: Don't boost anything over 0 dB, RX EQ goes away at very narrow DSP BW settings ... don't remember exactly where. You can reduce ranges above and below your pitch level to remove noise, although I've never been very successful at that. SSB: On advice from Jim, K9YC, I set the profile to approximate the shape of my hearing aids [inverse of my audiogram]. You can get +/- 16 dB, but if you lower the bands where your hearing is good and raise them where it is bad [usually the higher frequencies], you can effectively get about a 30 dB total range. You'll have to run the AF gain higher to compensate for the EQ reductions of course. 30 dB isn't even close to what my hearing aids do, but it does help a lot. Most importantly, follow Jim's advice and GO SLOWLY! I flailed around changing the settings to no avail and finally gave up and left them flat. When I went back and tried again following his advice, I changed one setting at a time and put operating time in between changes, keeping track of what I was doing in my station notebook. After awhile [multiple days], I could tell I was improving the intelligibility of SSB for my ears.

[Elecraft] CW RX
As a general rule with use of equalization, most EQ designs seem to have less phase shift effect when they are used in the attenuate mode as opposed to the boost mode. I've observed that excessive EQ in many applications will make an audio signal appear to sound as though it has a watery effect. Many traditionally will think in terms of add this or add that, when it is usually best to reduce the abundance of a portion of a audio signal. In other words, if your signal is reported lacking in high end, it is better to reduce the low end as opposed to adding to the high end. 73 Bob, K4TAX K3S s/n 10,163 On 8/27/2015 11:57 AM, Joe Subich, W4TV wrote: I use similar settings - except I follow the advice of Wayne and Lyle against using any boost in the EQ. __ 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 Message delivered to arch...@mail-archive.com

Re: [Elecraft] CW RX
Hi Mark, Barry's recommendation is what I did, however, there is one other thing to consider. This topic was discussed a few years ago on the reflector and Lyle advised that it was not recommended to peak up a desired frequency on CW. Only use negative settings for undesired frequencies. The reason was that at narrow DSP width settings like 50Hz or 100Hz the RX EQ is cut off. So if you had a peak setting of 8db in the RX EQ and you narrowed the bandwidth you would hear a sudden decrease in audio volume of 8db as you turned the width knob counter clockwise. Of course that was many firmware revisions ago so this might not still be true. 73, Mike K2MK pastormg wrote Good Evening, I have been tinkering around with the RX EQ #'s for CW.

This places the yagi one wavelength above ground which results in the major lobe of the antenna at 12 degree elevation angle when yagi is pointed on the horizon (I have no elevation control). Antenna dimensions were modeled by Mike-K6MYC with a gain of 13-dBi. The Moon peaked at 13-deg elevation during this pass so was perfect position for my antenna.

Both receivers are muted on transmit regardless of the antenna connections. The carrier operated relay will protect the receiver (or not), but it doesn't have any effect on what you hear.
