[Elecraft] PTT keying a KXPA100 with a K2
Hi, I own a QRP-K2 with the KIO2 installed. I want to PTT key a KXPA100 (not KPA100). May I connect Pin9 from KIO2 (8V in receive mode and 0V in transmit mode) directly with the PTT-IN connector on the KXPA100 (5V receive, 0 V transmit) ? Maybe with a diode (cathode KIO2, anode KXPA100) ? Thank you for advice 73 Luc F6HJO/HB9ABB __ 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
[Elecraft] Feeding 2 transverters XV144
Hi, I want to realize a 144 contest setup with 2 PA, 2 antennas and 2 transverters tuned on the same frequency with therefore a unique K3 switched back and forth only during receive. To do so, I want to feed two XV144 transverters in parallel at 28 MHz from the KXV3 TX path interface (dual port interface) (For receiving, I switch back and forth between the two transverters RX path). In the TX path, I intend to use a BNC-Tee with the common port attached to the 28 MHz KVV3 port and the each transverter connected to the other Tee-Ports. Is this OK or do I need a Wilkinson divider to feed each transverter with the assumed 50 ohm resistance ? I didn't find any impedance figure to be seen from the KXV3 nor from the XV144. Tu for helping me with advice.

[Elecraft] K3 event macros
Hello, In VHF weak signal traffic it's often very useful to end the transmission by a bip sound (the QSO partner knows you are now listening). To do this, I try to write a K3 macro launched by the release of the microphone transmit button. This macro could activate a voice recorder memory place with the bip recorded inside (sure, they are better solutions). Writing the macro itself is probably not a big deal but I didn't found in the K3 programmer manual how to launch the macro as the microphone transmit buton is released - a kind event driven programmation ! Any idea ? 73 Luc/F6HJO/HB9ABB __ 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
[Elecraft] KXPA100 et Smarttuner SG230
Hello,
My configuration : KX3, KXPA100 (with KXAT100, not used in normal
operation), coax line, SG230 (Smartuner), doublet.
My question :
In way to tune the Smarttuner, I must send some RF into the Smartuner
via the coax line. Before the tuning process begins, the SWR in the coax
line to the Smartuner may be very high. In this case, the KXPA100 goes
into Fault Condition ("Err Ant") ; no RF more, the tuning process stops.
Roundabouts :
1. PA off (via menu), tuning with KX3 barefoot.
2. KXAT100 on, KXAT100 tuning, Smartuner tuning, KXAT100 off.
Doing so (1. or 2 above), I can get the Smartuner tuned, but it's a bit
cumbersome.
Any idea ?

[Elecraft] K2 and X144
Hello, I have and odd and maybe difficult question : Is it possible to have one (and only one) K3 transmitting into two XV144 on the same frequency, but swaping between them on receive?

Re: [Elecraft] K2 LCD Issue
I had the same issue and resoldering the LCD did the job. 73 Luc/F6HJO Le 25/02/2014 01:02, Don Wilhelm a écrit : Don, That normally is the symptom of a solder connection that did not receive adequate heat during soldering. After a time, enough oxidation has developed to cause a problem. If you are fortunate, that bad solder connection will be at the LCD. Re-flow the solder for the LCD leads (I suggest soldering from the side the LCD is mounted on), and see if that cures the problem. If it does not, then the problem is with the soldering of Front Panel U1. Tell me which segment is not working and I can tell you which U1 pin that needs to be soldered better. Since the pins of FP U1 are covered by the LCD, the technique for resoldering is to carve away a bit of the plastic from the U1 socket and soldering the pin from the socket side of the board. 73, Don W3FPR On 2/24/2014 6:46 PM, donh wrote: Been happily on the air with my K2, but I noticed a few day ago that one of the segment of the LCD numeric display has stopped working.

[Elecraft] K2 : 8T rise and fall
I have an heavy trouble with my K2/100. During last french contest in SO2R setup, I made a mistake and keyed the K3 with the K2 still on the same band. I heard a strong noise in the K2, saw smoke and the TX was dead. RX OK. I've just replaced the 2 low level PA transistors : they were broken, both electrically and physically. Now the K2 has following behaviour : pressing TUNE, the PA collectors current rise very shortly, then fall. After 1 or 2 seconds, depressing TUNE has the same behaviour. I measured the 8 T line and the 8T voltage follows the same law. Suspecting any processor error, I made a reset (456POWER). No change. Any idea ?

[Elecraft] Trouble with K2 PLL reference oscillator
Hello YLs and OMs, I have an annoying trouble with the PLL reference oscillator in my K2 (1028): I use the K2, ever for hours, without any trouble. I switch it off. I switch it on within minutes : the PLL reference oscillator does'nt oscillate anymore I switch the K2 off and wait for 10 to 20 minutes : the PLL reference oscillator starts then like a charm. Of course, I've inspected and redone all the solder joints, looked for solder bridges, defect or unsoldered parts, and even more. I've tested the oscillator transistor Q19 and the diodes D18 and D16, looked for defect resistors or chokes (L31) and other discontinuities without detecting anything false or suspect. I tried to reproduce the trouble by heating the board with an hair dryer, without any success. Has anyone verified such a annoying behaviour ? Any idea ?

Interesting, interesting... I had a similar problem on 80 CW only : my note was T8 and garbling. I used a K2/100 and a SB220-PA. I attributed this behaviour to the weakness of the 220 V supply (engine driven generator). By why only on 80 ? More on this subject ?

Re: [Elecraft] K2 auto-detect feature
I've never had such a problem, even after 36 hours contesting.

[Elecraft] KCR2 with 2 radios, some questions
I'm considering the acquisition of a KRC2-unit, but I'm not sure it will fill my needs in my specific contest configuration. I want to use the KRC2 with a K2 with a KPA100, a KAT100 and a linear (SB220) as first radio, another transceiver as second radio, a PC-contest-program (TR-log or similar), antennas swiching-relais (to switch antennas back and forth beetween the two radios) and other switching devices for keyer and headphones. My question : is the KRC2 the unit I need ? Another question : the KRC2 manual mentions a "daisy-chain" to couple the KTA100 to the KRC2. What is this ? Another word to say parallel connecting ?
