Hi All Regarding the KPA500 RF / LPF boards. Are the inits matched paired, or can the LPF filter board be placed on another RF pwr module board. Thanks Ken..G0ORH __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listi

Re: [Elecraft] OT: For New Hams, How to Tell What an Amp Will Do For Your Signal

I guess I wasn't particularly clear, or maybe I just didn't say it often enough. If you are competing against other hams, such as calling CQ in a contest or calling DX from within a pileup, EVERY db counts no matter how good the propagation is. An amplifier will often win the day for you ev

Re: [Elecraft] OT: For New Hams, How to Tell What an Amp Will Do For Your Signal

Excellent point that you make Phil. If one can hear the 100 watt level, one can usually hear the much lower levels as well. That's a good demonstration that when the path is open, it is open and when it is not, it is not, Hi! >From my QTH on the Oregon coast I can usually hear those beacons on my

Re: [Elecraft] OT: For New Hams, How to Tell What an Amp Will Do For Your Signal

On a good day from my Kirkland, Washington QTH, I can hear three stations on the 14.1 MHz beacon. That would be 4U1UN, W6WX (always the loudest), and KH6WQ (usually the weakest because it is often off the back of my hex-beam). But, when I can hear any of these stations, I almost always hear al

Re: [Elecraft] OT: For New Hams, How to Tell What an Amp Will Do For Your Signal

Ron, I agree 100% Ron. I am elmering new hams and use the beacons as a good tool to explain the difference in signal strength with increase of power and relation to db's. Cant think of a better way to demonstrate. It gives credence to our explaining that they need to focus on the antenna sys

Re: [Elecraft] OT: For New Hams, How to Tell What an Amp Will Do For Your Signal

Yes. An amp that takes you up 10:1 in power, e.g. 20 watts to 200 watts or 100 watts to 1,000 watts, makes a 10 dB difference in signal -- just a bit over one S-unit. I pointed out the beacon resource as a good example of how often that extra power is not needed on H.F., especially for narrow band

I will put in a guess range: Lower kit price range: $649 - $699 Upper range kit price range: $749 - $799 I prefer the lower kit price range. Justification for the price points above is that the K3 100 amp option is $500 and that is just a board basically. So, a box, a heat sink, and power

For the newer hams, here's an interesting resource that will demonstrate to you what a DX signal sounds like at 100 watts, 10 watts, 1 watt and 0.1 watt. All you have to do it tune into the beacon frequency of 14.100, 18.110, 21.150, 24.930, 28.200 using CW mode and listen. The beacon stations in 1

Re: [Elecraft] KX3 Amp

I have been using my KX3 for a few months now, and never needed an amp. Nine out of ten times, if I hear someone, they can hear me (CW). Actually, even with my K1 at 6W, I never felt the need. For SSB, I can see how it would help, but for CW, it's a waste of money. Gil. __

I've been using a Tokyo High Power HL-45B and have been satisfied enough with it. It's only 50 watts and it doesn't do automatic band switching with the KX3 but the price point is well below where the Elecraft amp will likely be announced. Chris AB3QV On Wed, Mar 20, 2013 at 7:43 PM, Giff Hammar
