Re: [Elecraft] K3 DSP BYPASS
I don't think it's possible. Some dsp functions are not available with AGC off. Sometimes it's quieter with AGC off and reduced rf gain but not always. After 3 years, the best way to reduce hiss for me is to reduce hi cut (on ssb) sometimes to 2.4,sometimes 2.1. I would think in a contest you would be running narrow anyway but wouldn't want AGC off. Can the DSP in the K3 be bypassed? In other words, can it be operated as a conventional superheterodyne receiver without any processing? Would be interesting to do A/B comparison testing. Years ago I had a Ten Tec Omni 6 Plus, a great radio except for the horrid DSP hiss. I always wished I could somehow bypass or defeat the DSP just to see how much better it would be to listen to through a long contest without that awful hiss. 73 Mike R RIP- Mr 500.

Re: [Elecraft] Help - Elecraft Shutting Down
Ron, Most problems of that nature are not a problem with the K3, but a problem with the power system. Check your power supply and the power cord. All connections must be tight and the PowerPole connector that plugs into the K3 must have the contact blades fully inserted into the housing. Look at the business end of the connector - if you can see two metal ends (both the latching spring and the contact blade), the contact is not latched - push it further into the housing until it latches behind the spring. What is the voltage reported by the K3? If it is low, you might have a problem in your power supply. 73, Don W3FPR On 3/3/2014 4:43 PM, N6SC wrote: Elecraft K3 – The radio just started turning off and shutting down during this weekends contest.

Re: [Elecraft] K3 digital mode
Hi Mike, If you're using external sound for your data modes, you should have the mode set to DATA A, not AFSK A. Having your audio set to Line in DATA A mode is correct, unless you're going through the mic and phones jacks. Most people use the line in/out for external data modes (very handy!).

Re: [Elecraft] K3 Off Grid
David, I'll describe my setup for you. As others have mentioned, you need only 2 basic items, a 12V battery and some means of charging it. My particular arrangement is as follows: *100Ah Group 31 12V battery. Mine is an AGM type, which is safer than a wet cell type to keep indoors. *20A MPPT type charge controller to limit charging rate from solar panel to battery to protect wires and battery. *60W solar panel to keep the battery topped off or for QRP use. I had these on hand so use them when I can. *210W solar panel when I need to run full power for extended times, e.g., Field Day, contests, etc. *Battery charger for operation when sun is not available. Mine is a BatteryMINDer 12248; many others available. *TGE N8XJK Boost Regulator to keep the voltage to the K3 steady as the battery is used, and to filter the noise from the BatteryMINDer. *PWRcheck meter to keep tabs on voltage, current, etc. *1200W pure sine wave inverter; not needed for radio, but can run our refrigerator all day in case of grid failure. I also recommend the ARRL publication Emergency Power for Radio Communications by Mike Bryce WB8VGE to enhance your technical side. I hope this helps. Best wishes on getting your K3 off the grid. 73, Dave W8OV On 3/3/2014 6:03 PM, David Peterson wrote: I would like to operate my K3 off grid. I would like detailed information on this.

Re: [Elecraft] K3 Off Grid
I didn't read his question that way, it seemed he wanted to operate in places where there are no power lines. I sold my KPA100 and KAT100 because I was always using my K2 at low power in the field, in the last several years activating SOTA summits. I've settled on LiFePO4 as the best choice. It's not off the grid, all I'm doing is buying energy from Pacific Gas and Electric, stuffing it into a little package, and taking it with me in my pack. Incidentally, if you charge your big battery with a gasoline generator, you're still on the grid. From an economic perspective, energy is energy, if it's not electrons coming from the power company in wires, it's gasoline coming from a refinery in a pipe. Solar, wind, or if you're fortunate enough to own a dam, can take you off the grid. Be sure and include the capital cost of the solar panels, turbines, or the dam when you compute the cost of your energy. :-)) We all use propane here and my neighbor once commented that the price of propane tracked the price of gasoline. He was sure it was a government conspiracy [he has lots of those] and I don't think he believed me when I told him it's just economics. 73, Fred K6DGW - Northern California Contest Club - CU in the 2014 Cal QSO Party 4-5 Oct 2014 - www.cqp.org On 3/3/2014 8:53 PM, WILLIS COOKE wrote: I suppose that David wishes to operate free from the grid to prove a point, but the grid is very efficient and you cannot save money by generating your own electricity unless the cost of transmission lines is excessive, such as a mountain cabin or pipeline equipment in a remote location. __ 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] Off the Grid
The K3 runs on a car battery and an ordinary 60 amp car battery will run it for easily 24 hours without anything going amiss. I lived in Africa in the 70's and I never ran down the car's battery or the one in camp by operating my radios which in those days were Atlas and TenTec 2's. In the 80's I ran a 500 watt Metrum Solid State 500M amp and it had it's own battery and I would use it for hours keeping skeds from 5Z and 5H to W2. I had a generator in camp and would trickle the batteries whenever we ran the generator which was long enough in the day to keep the fridges cold. The batteries are the least of your problems as are the radios. If you are using battery chargers the automotive trickle chargers are more than adequate. Nobody operates off grid for hours and hours anyway. Whatever you have around to charge a car/truck battery when you inadvertantly leave the car on all night will work just fine too. Only the guys that use solar cells have to worry about overcharging batteries. None of us have to worry about car/truck/marine batteries running down in 24 hours and I believe frankly you could run a contest weekend with one too but have never done it. I have never worried about whether my voltages were 13.8 or 12. Nothing ever got below that for me and I used to ham for hours and hours when younger. Your off the grid antenna should be of more concern. I like long wires.

Camping is certainly Off Grid but it is not the first thing that comes to mind.

Re: [Elecraft] Off the Grid
This might be helpful. I operate out of a parked RV, mostly using a 30A AC main power cable (so-called shore power). As a result of a nasty 220v surge (details below), I needed to buy a whole-line surge protector, which just happens to have a continuous, cycling display of line voltage, frequency, and amperage. So I ran a few measurements to see how much power I drew at 120v AC, translating my measurements into DC amps at 12v. My K3, on receive, with the KAT500 in-line, the P3, and my massive 70A Astron p.s. powering the K3, drew about 20A DC. Putting the K3 in transmit mode, with just under 12W drive (so as not to kick in the 100w amp) required about 30A DC. Boosting the output to 50W drew about 70A DC. Running it wide open, at 100W out, required about 80A DC. And finally, turning on the KPA-500, with 15W drive to yield 300W out, required 150A DC. These readings might be useful if you're trying to calculate running times for your equipment using batteries instead of line (mains) power. If you operate on deep-cycle batteries, I don't believe you should consider discharging your batteries below 50% of their rated amp-hour capacities. Now back to the 220v surge. This was apparently caused by faulty components in the sub-main service panel serving my RV line. The surge protector I bought is a Progressive Industries PT30C, $248 from Amazon.com. It seems very ruggedly built and is supposed to be waterproof (it's outdoors), although I cover it with a plastic box as a precaution. While its price may seem steep, I wish I had bought it before the surge, which blew out two pricey surge strips, my 12v converter/charger and distribution panel, and my (direct wired) microwave oven (the surge fried its control electronics). This is a warning for other operators running from shore power as I was. The situation is supposed to be even worse for those using campground RV hookups. -Paul, N1HEL ___ recently had to buy a On 3/4/2014 10:48 AM, William Levy wrote: The K3 runs on a car battery and an ordinary 60 amp car battery will run it for easily 24 hours without anything going amiss.

Larry, Why not measure the current. Break the positive 12 volt Power Supply connection and insert your DMM set to measure current. Then short the keying input line on the relay box. You DMM will tell you how much current is being drawn. A new K3 has a 1 amp rating on the 12 volt output.

I need recommendations on wiring the Plantronics CS50 base unit to the back panel mic and phone connections with the standard four wire line from the Plantronics base.

If I'm reading this correctly, on receive, you're drawing 240 to 280 watts. At 12 watts, you're drawing 360 to 420 watts. For 50 watts out, you need more than 800 watts in. Someone else suggested that a 60 amp-hour car battery would probably run the rig for a day. If I'm reading this correctly, you'd do no more than 3 hours if you did not transmit. For lead-acid batteries, you don't want to exceed the 10 hour rate, so the smallest acceptable battery would be over 200 amp-hours, and only for just-receive. Something seems a little off. -- Lynn On 3/4/2014 2:41 PM, Paul Grigorieff wrote: My K3, on receive, with the KAT500 in-line, the P3, and my massive 70A Astron p.s. powering the K3, drew about 20A DC.

I power my K3, P3, and KAT500 with a Yaesu 1030A power supply. The KPA500 is plugged into the wall of course so I turned it off. At 100W the total current is 21A for a total efficiency of ~40%. I get closer to 50% out of my K2 @ 5W output. The K3/P3/KAT500 combo drain might be 1A in receive, the scale is really cramped that low. 80A at 12V is 960W for an overall efficiency of ~11%. That seems awful low to me. A friend gave me a solar panel with a 12Ah SLAB in it. I've only had the chance to use it with my K2 in one Spartan Sprint [too cold out on the deck], but I may do QRPTTF with it at the end of April if I don't do a SOTA Summit. The sun is headed back north but the sun angle is still not normal to the panel and looking at the charging current vs the average drain when I'm keying the K2 on CW @ 5W, it appears I could send all of War and Peace during the day and not drain the battery. :-) When I'm on the solar panel, I'm essentially off-the-grid, all the energy in the battery is solar. All the rest of the time, we are definitely *on* the grid. 73, Fred K6DGW - Northern California Contest Club - CU in the 2014 Cal QSO Party 4-5 Oct 2014 - www.cqp.org __ 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
Re: [Elecraft] Mic and headphone

Re: [Elecraft] Mic and headphone
Allen, Most modern audio output stages are low impedance sources, and there is no need to match impedances. Do you think about matching impedances when you plug something into a power mains wall receptacle? Likely not, because the AC mains is a low impedance source and will deliver whatever the device needs. Your headphones are similar - with a low source impedance driver, you don't have to worry about it, just adjust the AF gain to a comfortable level. More power will be delivered to a low impedance device, but headphones do not require much power. The microphone is similar. It is a relatively low impedance source, and it is operating into a relatively high impedance device (1k to 10k for modern transceivers) and the voltage produced is the important parameter. Yes, high impedance microphones may not give the proper frequency response curve, but other than that, no impedance matching is normally required. Modern microphones are in the range of 200 to 600 ohms driving impedance. I suspect yours is also in that range. 73, Don W3FPR On 3/4/2014 7:12 PM, N5AG wrote: Has anyone wired up a Plantronics CS50 Telephone headset system to the K3?
