[Elecraft] K3 Internal 70MHz Transverter

For those interested in such things, I see an aftermarket 70MHz Internal K3 Transverter with 28MHz IF on ebayuk. It is made in EA9. Item # 121290408912 also shows on ebay.com Dave G4FRE __ Elecraft mailing list Home:

Re: [Elecraft] KX3 Power Socket

I had the same issue with my kx3. Investigation revealed that their was a dry joint between the power socket and the PCB. Soldered it properly, not had the problem since Dave G4fre Date: Mon, 17 Feb 2014 16:26:00 + From: Dominic Baines dominic.bai...@ntlworld.com To:

Re: [Elecraft] KPA Aux cable

I did for a while use that signal for my transverter interface, see http://g4fre.com/k3vhf.pdf and http://g4fre.com/K3_PTT_sw.htm IT got messy when I changed XVn settings, so I moved onto sniffing the frequency in the rs232 stream and switching transverters based on that, see

Re: [Elecraft] K144XV Option

There was talk by Wayne when the K144XV was introduced that the K144XV could be wired for a separate 144rx ports, but I have seen nothing written up so far. I noticed that there was a 3 pin header (normally with jumper) near the unused cable outlets marked 144IF in the box cover. Investigation

Re: [Elecraft] [600MRG] Use of K3 on 600m (and below)

I am still waiting for 10MHz to be available as an IF band on the K3 to enable a 10MHz rubidium or GpS standard to be used as a local oscillator While I wait, I use my anan-10 sdr which produces ~5W on the band and has had qsos Dave Ww2r, g4fre -Original Message- From: 600MRG

Re: [Elecraft] K144XV Strange Readings

Both my early edition K144XV were not unconditionally stable and were swr intolerant I think you will find that the 3:1 swr is because it is oscillating out of band. Try listening on a scanner. I have experienced this on my two k144xv and g4ddk had the same issue with his. One example produced

Re: [Elecraft] K3 with 2m module K144XV

Lance Having tried the K3 with the high spec oscillator and with the external locking I found I needed the external locking for my 144 digimode qsos. However my eme shack varies between around 37F and 110F (outdoor garage) so it is expecting a lot of the internal reference External locking of

Re: [Elecraft] 472KHz transverter for KX3

It would make the maths even easier if one could set XVn IF to 10MHz (and XVn RF to 0MHz), one could then use the K3 external 10MHz reference as the Transverter Local oscillator Last time I checked Wayne was working on the software to give the KX3 the same xverter driving capabilities that the

Yes, I do I use my k3 2mtr option to drive a home built amp using the I0JXX 500w 2m module with PIC control/monitoring and an LCD display, see http://g4fre.com/500w144pa.htm Just about to upgrade to an F1JRD 1kW module using the MRFE6VP61K25H device that was in DUBUS Dave Ww2r From: Phil

Re: [Elecraft] KX3 offset with transverter

As far as I knew the KX3 supports none of the menu settings that you mention until Wayne writes the software. They only work in a K3. Dave G4FRE From: Erik Overbye Olsen la4...@nrrl.no To: elecraft@mailman.qth.net Subject: [Elecraft] KX3 offset with transverter Message-ID:

Re: [Elecraft] KX3 and digital modes

Following the listed procedure made made my KX3's previously iffy performance on 6m digimodes acceptable and even just about acceptable for HF QRSS. I used the 5th harmonic of my K3's 10MHz GPS locked reference as the calibration signal Dave Ww2r Message: 14 Date: Mon, 19 Nov 2012 18:13:03

[Elecraft] KX3 Band Decoder

With the CQWWSSB coming up next weekend I decided to work on solving the nagging issue of not having an HF band decoder for my KX3 to automatically select antennas and switch the Low Pass filters. I am using the RS232 data from the KX3. The writeup is at http://g4fre.com/KX3_RS232_hf.htm Dave

Re: [Elecraft] Question about KX3

I met the same problem with the K3 and devised a switching system based on sniffing the rs232 data. See http://g4fre.com/K3_RS232_sw.htm It can decode/drive 8 transverter bands. It gives a 1 of 8 band output and a 1 of 8 ptt It also works with the KX3, I just tested it, although until Wayne

Re: [Elecraft] 472KHz/500KHz

It would be even easier if one could use a 10MHz IF for LF. For this the K3 and KX3 (when the code is written) xverter settings could be set to XVRF=0MHz XVIF=10MHz. This way the accurate 10MHz reference, already applied to the reference input to the K3 could be used as the local oscillator in the

I also got the same reply from Vicki at elecraft on 5/17 that it would be shipped next week ie the week now ending. Having not received the despatch notice I called her 2 hours ago to enquire and was told the 20 outstanding orders are now ready and will be shipped next tuesday Dave ww2r

Re: [Elecraft] Elecraft Digest, Vol 85, Issue 34

I was also involved in the beta test. I was/am using the K3 as supplied 5ppm oscillator and a rubidium 10MHz source and I managed to maintain 2Hz accuracy at 50.26MHz (40ppB)which is fine for the VHF/microwave weak signal modes I needed it for. Dave ww2r Message: 8 Date: Fri, 20 May 2011
