Re: [Elecraft] P3 burn-in concerns?
The data sheet for the display we're using specifies an LED lifetime of 10,000 hours minimum. I expect that's probably a conservative spec. I've had mine on for thousands of hours so far with no noticeable change.

As David noted, burnout is very rare. Should it happen, you can replace the LCD yourself with only a screwdriver.

The LCD are, of course, available direct from Elecraft. 73 Ron AC7AC -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Ralph Parker Sent: Monday, March 11, 2013 3:40 PM To: Elecraft@mailman.qth.net Subject: Re: [Elecraft] P3 burn-in concerns? >No. The only possible issue is backlight failure, just like your >computer or TV screen.

That would depend if the backlight is LED or cold cathode.

Re: [Elecraft] OT: beware of strange replies to your ads
Yep Had one of those years ago. I had a wanted ad on Eham for a power supply for a KW2000b. individual claiming he was from England replied that he had the item I was looking for with some sketchy details he said the tubes had all been tested and were good. What tubes?. I strung him along for a while asking stupid questions about non existent wood trim and other nonexistent features. Each indicated that the features I asked about were all fine. and of course each reply ended encouraging me to wire money. Finally I sent the whole lot to the fraud dept of the RCMP.

Re: [Elecraft] K3 Receiver Mute
Assuming your antenna relay provides enough isolation to protect the K3 receiver front end, what about using an external speaker with the K3 and accomplish muting by switching the audio out from the K3 to an 8 ohm resistor instead of the speaker during transmit? You could then perhaps monitor your transmitter on a P3 if you have one. 73 - Mike WA8BXN __ 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

Elecraft K3 Build – Parts separation and Day 1 Build So I will say upfront this is not the most exciting part of the build – I will say that I was not feeling 100% while working on this section so I didn’t get as far as I wanted and I also found that it’s pretty stressful trying to build, read, get things right and be on video ☺ http://nicktoday.com/elecraft-k3-build-parts-separation-and-day-1-build/ __ 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

>No. The only possible issue is backlight failure, just like your computer or >TV screen. Tnx, Ron, just what I was hoping to hear. I usually turn the radio on in the morning, and off in the evening, longer periods only in a contest. Should I be concerned about the backlight? I've only had two burn out, one in a laptop (NEC) and one on a desktop monitor (Dell). I would suppose that the entire display module would have to be replaced.

Re: [Elecraft] [KX3] Portable Antenna question
I too use the MP-1 Super Antenna, but replaced the flimsy collapsible whip, which I lost one windy evening, with a 10ft Buddypole whip! It's a bit longer but much more robust. The MP1 needs to be tuned carefully, and collapsed a section to resonate on 10m with the Buddypole whip, but otherwise it's a real good backup when I don't have my 32ft push-up pole.

Re: [Elecraft] [KX3] Portable Antenna question
Hi Steve, Them MP-1 is a pretty neat antenna. You can set it up from the inside of a tent when its raining (right outside the door). Its a compromise length wise but well built. I would suggest NOT putting any antenna on the BNC connector of the KX-3 because of the strain on the BNC connector in the radio. (I would not use any hard connector like an 90 degree BNC to connect an antenna either). Use some coax between the rig and the antenna and find a suitable and cheap to fix if needed way to support the antenna. 73/72 - Mike WA8BXN ---Original Message--- From: ke6...@gmail.com Date: 3/11/2013 4:55:17 PM To: elecraft@mailman.qth.net; Lynn W.

Re: [Elecraft] General coverage bandpa
I put BPF boards in both receivers but if I had only one it would go in the sub RX. 1) I am more likely to use the out of band Rx for listening to the "AM Band" and using the Sub RX with a separate antenna eliminates the losses associated with the pin diode T/R switch. 2) I am likely to want to use the main RX for normal ham operations while listening to something else (WWV, route weather, SW BC, etc.) and having the second RX available for the SWLing even when using the transceiver normally "just makes sense". On the other hand, if I had a need to *transmit* outside the ham bands I would have no choice other than to put the BPF in the main RX. 73, ...

Re: [Elecraft] [K3] RE: S Meter
I must be missing something in this recurring "RF Gain" thread. In the "olden days" before product detectors [think SX-28], for CW, you turned AGC off, AF gain to max, and used the RF gain. The BFO produced a constant signal that activated the AGC if it was on, and with the RF gain at max, the received signal was way too high at the mixer compared to the BFO level which was constant. The S-meter didn't work for CW and that funny sounding new mode called SSB. Today, I run my K3 with RF gain at max, AF gain controls the volume, AGC is on ... SLOW for SSB, FAST for CW ... all the time. After all the comments in this thread, I've tried "riding the RF gain" with AGC off on very weak signals. CW signal readability doesn't change. If I could barely copy him with AGC on, I can equally barely copy him without AGC. The only effects I can find are: 1) I'm fiddling with the controls a whole lot more and if QSB occurs he disappears until I manage to bring up the gain; and 2) A strong station that appears in the passband is really really loud in the cans. I leave my P3 set with dBm on the ordinate. Except on RTTY, the P3 averaging prevents the apparent peaks from actually matching the peaks on the S-meter and I kind of like to see the real baseline noise level at the receiver input. Based on this thread, I must be doing something really wrong. My K3's AGC does a super job of controlling the RF gain, far better than I can do manually, and my S-meter works in all modes. Explanations on what I'm missing are welcome. My "rememberer" remembers a receiver that had both a real RF gain control and an IF gain control separately. I don't remember the name however. I'll look in Fred Cady's book this afternoon and see if the K3 HW AGC is actually applied to the RF stage [not sure there is one], the first mixer, or just the first IF amp chain. I remember audio-derived AGC ... it was OK for phone, not so much so for CW. 73, Fred K6DGW - Northern California Contest Club - CU in the 2013 Cal QSO Party 5-6 Oct 2013 - www.cqp.org On 3/11/2013 3:08 AM, Mike Rodgers wrote: By the way, I don't want to incur the cost of a P3 to "fix" the RF Gain PAIN.

Re: [Elecraft] K3 Speaker Amp Protection
> http://www.elecraft.com/K3/mods/AF_Output_Mod_Rev_C.pdf This is an entirely different (and older) modification. Output Mod Rev C is designed to prevent damage to the right channel of the AF amp when it is "open circuit" as it is when SPEAKERS=2 with a single speaker attached. The modification that Paul is inquiring about is designed to protect the AF amplifier when the output is short circuited - e.g. connecting a *mono* plug with SPEAKERS=2 - or in case of overload (a sudden static "crash" or high level carrier with AGC=OFF) when using low (4 Ohm) impedance speakers. The latter modification has never been documented but I assume it involves adding 2R2 or 2R7 resistors in series with the blocking capacitor - perhaps replacing L13 and L16 on the KIO3 Audio Board. 73, ...

Re: [Elecraft] [KX3] Portable Antenna question
My favorite is a 20 meter DEZ, 86 feet fed in the center with open wire line. Works OK on 80, good on 40 and 30, excellent on 20 and 10 and ok on 17, 15, and 10. Now in my current apartment I hid 43' up a tree and hid 43' horizontally. I feed it with open wire line from a balun connected to the back of my K3.

Re: [Elecraft] K-3 S meter
Mike, I also would like to see the S-meter deflection done away with. It is not practical to use the P3 to indicate signal strength because of constant looking back and forth from the rig to the P3. It's "another step" from just being able to look at the K3 S meter. Some may not find that a problem, but for me it is not intuitive. Not only that, but the P3 is expensive, especially if you have the SVGA board. Someone posted here that this would take a hardware mod and is not doable by firmware. So, I have decided to try one of Ten Tec's rigs, maybe the Omni 7. Quadruple band stacking registers sounds nice, and no more S meter deflection. Not a highly rated rig according to Sherwood, and certainly not the best for CW because the BW is limited at 300hz. (maybe 200hz) But, for casual operating this might be nice.

[Elecraft] [K3] RE: S Meter
I'll second the comments below. By the way, I don't want to incur the cost of a P3 to "fix" the RF Gain PAIN. I'm just having to live with it. ate: Wed, 06 Mar 2013 10:30:51 -0500 From: drewko To: Elecraft@mailman.qth.net Subject: Re: [Elecraft] K3 S-Meter Message-ID: Content-Type: text/plain; charset=us-ascii Don, I always seem to have my RF gain adjusted by ear to below where the s-meter will deflect on a particular signal. So I will most always have to readjust the gain to see an s-meter reading. The RF gain can be adjusted much lower than the signal's meter deflection point but still have an audible signal. A moderate strength signal can still be heard when the RF gain has been turned down to the point where the s-meter incicates s9+40 db. The more I think about it the less useful it seems to have the meter deflect upward with a lowered RF gain setting. Does anyone find this action useful for tuning in a signal? I know that I would be fiddling around with the RF gain control a lot less if the s-meter display was not affected by the gain control. Why not make the s-meter "absolute mode", which is independent of the attenuation setting, also independent of the RF gain control? That seems more consistent and logical to me. 73, Drew AF2Z 73 Mike R Play me some fiddle, but no stinkin' violin!

Re: [Elecraft] The P3 Effect
It's still as tough as it's always been, just like a hailstorm of callers for which you need a good rx and even better ears to sort out. As the population of P3s and other panadapters expands, more random listening might help, rather than ploughing a furrow. David G3UNA T32C Perhaps this is why DXpeditions seem to play "spin the dial" more; having many stations converge on the last rx frequency probably tends to slow their rate. I experienced this effect at PZ5RO. It would be interesting to get feedback from DXpedition ops. 73, Redd - AI2N __ 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
