Re: [Elecraft] K3 - A different RTTY question
Exactly my findings at MW2I. Normally we dont use dpb as incoming signals arrive all over the place frequency wise (in arrl rtty 2010 3 people called over 1.5khz off!) outside the dpb passband.

Since a K3 only has one PTT output, I have built an interface board that takes the LP Keyout, DIGOUT0 and DIGOUT1 and generates a separate PTT output for HF, 6m and non-Elecraft transverters that use the low power outputs from the KXV3. It also provided a switched 12v to control the 6m preamp since DIGOUT1 is used on this board. The board contains 6 RCA jacks, one is 12v in from the 12v jack on the K3 rear panel and another RCA is provided with 12v out. There is a switched 12v jack that is activated on 6m for the remote preamp and then the 3 PTT output for HF, 6m and VHF transverters. This is not in competition with the KRC2 which does band decode and lots of other cool stuff, this is a quick and easy way to control amps and transverters. It is NOT for folks running QSK as the relays are typically 35ms switching. I will have some pictures up on the K8GP website tonight. I have about $30 in parts and will provide the units assembled and tested. You will have to provide a interface cable with a DB15HD for the ACC connector on your K3, the other end of this cable connects to this board via a push on connector (supplied) and a suitable enclosure.

To: elecraft@mailman.qth.net Message-ID: 001001c9e078$0f538940$2dfa9b...@biz Content-Type: text/plain; charset=us-ascii Jim, you said supposedly accurate. A Bird wattmeter is accurate only if it's been properly calibrated and handled carefully - especially the slugs. Bumps and bangs can easily ruin the calibration (That's why all Birds used in critical applications carry calibration stickers showing when it was last checked - normally no less often than annually - and is carefully handled and stored in approved containers). Let's assume the Bird is recently calibrated and treated kindly: 1) Its calibration is then dependent upon using the right slug. You probably know better, but a surprising number of Bird owners think the frequency range on the slug isn't very important. I believe the proper Bird 43 element for 6 meters is the type A slug spec'd for 25-60 MHz. 2) Are you allowing for the normal error in even a perfectly-calibrated Bird? That's +/- 5% of *full scale*. IIRC the Bird 6 meter slugs have full scale ranges of 25 or 250 watts. If you're measuring 100 watts with the 250 watt slug, the possible error in a properly-calibrated Bird is +/- 5% of 250 watts *anywhere* in the scale. So at 100 watts indicated, the actual power may be anywhere between 87 and 112 watts. That's plenty good enough accuracy for nearly all field use, including for showing that transmitter power levels comply with FCC regs (although when I demonstrate a marine transmitter to FCC engineers, it's *their* Bird that is the final word ;-) Now, the K3 has simply another wattmeter built in, so it's normal for the two wattmeters to disagree by the sum of their possible errors. You asked, Which one is more accurate? One of the Elecraft engineers would have to answer that, but let's assume the K3's built in wattmeter is as good as the Bird. In that case a perfectly calibrated Bird on a perfectly calibrated K3 may disagree by as much as 15 watts at 100 watts giving you an indication of anywhere between 85 and 115 watts on the Bird when the K3 meter says 100 watts. And don't forget that assumes everything is in perfect calibration. In the real world, it's not unusual to see a greater error. That's why it's not normally considered important for owners to worry about the K3's power calibration. Unless you have some laboratory standards to compare to each other and to the K3, it's almost impossible to improve on the default factory settings. Ron AC7AC -Original Message- Gentlemen, How accurate is the built-in watt meter indicator in the K3??? I'm asking because when I've used a supposed;y accurate Bird 43 while measuring the K3's various outputs on the various HF bands there seems to be a slight discrepitancy between what the K3 is showing and what's actually there according to the BIRD!!!

Absolutely! I've been playing with an RFSpace SDR-IQ and a beta version of Spectravue. It provides panadapter and waterfall that can be set anywhere from 1 to 190 KHz wide ... clicking on it will tune the K3 to put the narrow filters in the right place. N8LP's LP-Pan and PowerSDR should also be able to provide the same capability. SDR-IQ and SpectraVue work very well with microHAM Router since SpectraVue's new external panadapter function can use Router's 2nd CAT port to control the K3 at the same time as a logger and digital mode package like DXLab Suite or HRD/DM780. 73, ...

Re: [Elecraft] Transverter offset
If by offest you mean the transverter offset (config: XVxOF) it applies to both VFOs. This brings up another interesting K3 Xverter observation from the VHF contest a few weeks ago config: XVx RF allows only 3 digits of MHz, quite reasonably, because thats all the display can show. However it is these 3 digits of MHz that the RS232 will report. Example on 1296 with Xv4 RF set to 296 rs232 reports 296.100, which is not recognised by the logging program as its not a ham band. I have already asked elecraft for a feature request to allow 5 digits of MHz to be entered in Config:XVx RF and be reported by rs232 but (as now) only show 3 digits of MHz on the display Currently the work around (on 1296) is to tell the logging program and the F1EHN tracking software (for auto doppler correction) i am using a xverter with a 1 GHz local oscillator so 296 appears as 1296 again Dave ww2r -- Message: 44 Date: Sat, 7 Feb 2009 17:55:20 +1300 From: Ross rbig...@ihug.co.nz Subject: [Elecraft] Transverter offset To: elecraft@mailman.qth.net Message-ID: dd9395eacc3b4b8d9842a9023e529...@rossbeast Content-Type: text/plain; charset=iso-8859-1 I need to put in an offset for 1296EME into the transmitted signal.

Re: [Elecraft] Silly question - what is KEY OUT?
Do not be mislead by the manual as I was last weekend during the VHF contest. The LP has nothing to do with low ***RF*** power. It is active when producing 100W or 0dBm in transverter mode. Currently there is no K3 keying output that is ONLY active when transverting. To achieve this I had to gate the KEYOUT-LP on pin 10 and the DIGOUT0 signal on pin 6 Perhaps it should have been labelled LC (low current)?
