Re: [Elecraft] [K2] Mic bias bypass?

Out of the box all pins on the microphone connector are open circuit. There is an internal jumper block that has bias free microphone audio and resistor free 5 volts on it. If you are seeing 5 volts on pin one on the external connector it is because someone has wired 5v to it. There may or

Re: [Elecraft] K3 FSK RTTY Problems

Ralph, I normally use MMTTY, with DXLabs. That is not the problem, the Mark output of the radio is at ~200hz, NOT 2Khz as normal, and can not tell if the space is there or not, due to the super low frequency offset from the dial frequency. I'm setup for SO2V operation with Writelog,

[Elecraft] K3 FSK RTTY Problems

Hi All, This weekend my K3 stopped working with FSK. AFSK works just fine. I have ran many RTTY contests with the K3 in FSK mode, using various software drivers. The problem is I get a single tone, but at the wrong frequency, Its about 200hz, not 2125Hz. I checked the pitch setting,

[Elecraft] K3 DSP processor speed

I was informed by an ICOM 7851 owner that the ICOM has DSP processors are 10 times as fast as the K3 and therefore has noise reducing advantage. Not that important to me but curious if this is meaningful and if there is consideration of chasing this performance spec by Elecraft and if not Why not?

Re: [Elecraft] K3 battery and RRC1258?

Tom, I can answer about the Low Battery part of your question - that has to do only with the power supply voltage delivered to the K3 (not the coin battery for the Real Time Clock). There is a BAT MIN menu item where you can specify the voltage below which that message will be blinked on the

For those who have not yet snagged a station on the fabled MF band below 500 kHz, here's a chance to listen to one of the last operating commercial CW stations (although it is now officially a museum. Since I worked them often in their heyday I guess that makes me officially a fossil). 14

I make all my audio cables out of plain old CAT5 cable (be sure to use the stranded variety). The stuff's a real bargain, and the twisted pair construction makes it a great choice around RF. I picked up a 100 meter spool in eBay for around $30. I either don't use the spare pairs or double 'em

Re: [Elecraft] K3 DSP processor speed

The K3's DSP code is written in very efficient assembly language. It executes quickly, because it doesn't need the lengthy library-routine calls typical of the C or C++ code written for GHz-clock DSPs. The code is also extremely compact. The crystal oscillator frequency is not a direct

Re: [Elecraft] K3 DSP processor speed

While I appreciate the input from Wayne on the K3's programming architecture (as well as the facts on the power consumption characteristics), the reality is that many of us have identified other rigs that have implemented NR in a way that produces results that are much more satisfactory. Comments

I am trying to use the Tx Inh (pin 7 of ACC) to allow the K3 to xmit only when my 2M EME sequencer allows. In testing out this function, I find that when Inh Hi or Lo is used, once you apply a logic change to pin 7 the Tx Inh will lock in the on position. Removing the logic signal, or returning to

If you are using MMTTY make sure that you have the "EXTFSK" patch set up in both the TX setup window and the Misc window. I get tripped up on this every once in a while. If these settings are correct you probably have a physical problem with the FSK keying lead between the interface and the

Re: [Elecraft] K3 FSK RTTY Problems

Gordon, It's not clear what you mean. The mark output from the radio is at RF, not at either 2 kHz or 200 Hz. Do you mean the audio monitor tone you hear from the K3, or are you monitoring in some other way? In FSK D (and also in AFSK A), the K3's dial displays the actual Mark frequency as

Rich, Sorry, I am going by the monitor tone. I need to check the actual rf on another radio and see if the Mark is really at 200hz offset or at 2.1Khz like it should be ( I use high tones from mmtty or 2tone) the AFSK A is working normal. I did not hear any shift using FSK D. I
