Re: [Elecraft] 6kHz Filter Install in K3
From the manual … (K3S p 85 — same rules apply to K3) "Rule #2: You can install any filter in any slot, and can leave any slot empty in anticipation of installing a crystal filter there later. However, you should install the widest filter closest to FL1, the next widest to its left, etc. “ So yes, you should move the filters.

[Elecraft] 6kHz Filter Install in K3
I am installing a 6kHz filter in a K3. The current filters are in positions FL1, FL2 and FL3. Do I need to move the other filters so the 6kHz is in the FL1 position? Thanks in advance. __ 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] KPA500 fan won't shut off
"It then sets the fan for full speed operation to bleed off the 60 V power and waits for the power button to be released." I don't think fan is set to high speed to bleed down the 60 V supply. I think it is set to low speed but may revert to high speed when the firmware shuts down with 60 V is still present. Try this simple test - With KPA500 powered and On, use menu to set minimum fan speed 6. Then shut down with the front panel On button. Fan immediately reduces to speed 1 and holds speed 1 until it slows down as the 60 V supply bleeds down. The firmware could detect that 60 V has not decayed below min monitor threshold and issue a fault. That fault code could perhaps alert the operator to turn off the rear panel power switch and seek assistance. Better to be alerted at shutdown time than find the fans still running the next day. There is a potential safety issue with a stuck 60 V enable relay. The interlock switch is in the relay coil coil circuit and offers no protection if the relay is stuck on. On the other hand - how often does the 60 V enable relay fail 73, Andy, k3wyc __ 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] KPA500 fan won't shut off
Dinner on Andy? Your analysis is spot on. When the KPA is requested to shut down it does some housekeeping, saving various things and putting the amp into a safe condition, including setting the 60V to off. It then sets the fan for full speed operation to bleed off the 60V power and waits for the power button to be released. It finally resets into the boot loader. It does not monitor the 60V voltage at that point. It is an interesting observation that perhaps it should, but the question is then what to do about it. The only thing really is to throw a fault, which puts that amp into a safe mode, but we are already there. As usual, Andy, you provide great things to think about. I’m not sure there is anything to do about this one, except find out why Jerry’s 60V power is stuck on. 73 and thanks!

Re: [Elecraft] KPA500 fan won't shut off
Kevin - As I read Jerry's post, I believe his fan was running even after the amp had been shut off all night long... and the only way to get it to stop running at full speed was to either turn the amp on... or turn off the power switch on the rear. He also stated that the menu setting was set to NOR, so I think Jack is on the right track to check with support.

Re: [Elecraft] KPA500 fan won't shut off
The KPA runs a check on the memory contents when it starts up. If something has changed that should not, then it will ask for a fresh firmware load. Since Jerry is not seeing this, then I don’t believe there is a firmware issue. I _am_ concerned about the issue, which is why I suggest calling tech support when they open tomorrow. This has the feel of a stuck relay on the power supply board, but I am sure my friends in Watsonville will have a better idea as to what might be happening. 73!

Jerry: Maybe clarify. I think Jack's concern is that your fan was running even with the power off. That's not the case, right? The fan just came back on full when you turned the power back on? Try Menu, scroll down to FAN CTL and make sure that say NOR. If it has a number instead, you somehow accidentally set the fan on at that speed. Just use the down arrows to get back to NOR.

That means the power is not shutting off. We bleed off the capacitor charge through the fan at front panel shutdown, which is why you hear the fan run for normally a short time.

[Elecraft] Any problems with this 6m setup with KPA500?
A few of us are planning an multi-operator operation for next weekend's CQ WW VHF contest, cobbling together equipment from different places. I am wondering if there are any potential issues (most likely with switching timing) with the following potential setup for six metres: Radio: K2 (QRP+KXV60, with ground-on-transmit T/R keying output), 8R hold ON, with some reasonable release time for semi-break-in CW) Transverter: homebrew, 10 watts out max., relay switched, but the relay is faster than the K2, so no sequencer needed normally Intermediate amplifier: an ancient Lunar 6M10-120P, which is an RF-sensed only (no T/R input available) 100-watt class amp, with K2 drive set to give around 30 watts output. Up to this point the setup has been tested and works fine. Final amplifier: KPA500 I'd plan on adding a second T/R output from the K2 somehow, so the transverter and KPA500 can be keyed at the same time. Modes of operation: CW, SSB, FT8, FT4?, MSK144. I haven't quite got my head around what would happen on non-CW modes where the release delay for the T/R output is zero. In this case the transverter and KPA500 will switch from transmit to receive before the intermediate amplifier does (using its own internal delay timing). Is that likely to cause any issues? Any other timing problems you can think of? Do I need a sequencer? Would the KPA500 survive 100 watts input if, for some reason, the drive level is set too high by mistake? My understanding is that it should initially switch in an attenuator and then hard-fault (switch to straight-through operation). Correct? 73, Steve VE3SMA __ 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

Make sure BOX is ON on all bands. Make sure not in TEST mode on bands with no CW out.

Re: [Elecraft] No output on CW with K3
The YCCCN Remote OPs group (VY1AAA) uses the K3S at this site (VY1JA) and reported the same problem but only on Six meters. The K3s is working perfectly on all other bands. It has been confirmed that the CONFIG does not redirect TX output and tests on TUNE show good output on 6 and low antenna SWR there. As soon as this unit is switched to CW on 6 and keyed, there is no output. Next troubleshooting steps for getting this GG for the RemoteOps?
