[Elecraft] 4W/G3ZEM

I want to acknowledge the superb performance of my K3, KPA500, KAT500 combo along with my little HF9V while away on my solo 'man in a tent' trip to Timor-Leste. The nominal 220V supply in T-L rapidly ranges +/-20% when it is available at all This would be a challenge for any equipment. Aside

Re: [Elecraft] KPA500 fault at H44KW (no pwr high SWR)

Not to contradict the expert but in addition to the specified parameters I would want to know the on resistance (Ron) and the gate threshold voltages were the same before I would sub. 73 Fred, AE6QL -Original Message- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of

Yes, the 2m module is a nice add-on; here at home, I use mine to drive transverters for 222, 902, 1296, 2304 and up. On 2m, with just 2w, I'm able to drive my SSPA to a full KW out (see the Oct 2012 QST article on the amp, or on the w6PQL web site). I do notice an instability on 2m, and hope

[Elecraft] Elecraft CW Net Announcement

Good Afternoon, After a week of incessant rain broken by only a few minutes of sunlight the fog is once again enveloping my house. The fir, cedar, and ferns are all enjoying the moisture; moss is glowing everywhere. The long range forecast is for a mild, but very wet winter. By the time

Re: [Elecraft] KPA500 fault at H44KW (no pwr high SWR)

Hi fred, The parameter is Rds(on),max The IRFSL9N60A is .75 ohms at 9.2 amps and the IPA50R399CP is .399 ohms at 9 amps. Q4 and Q5 are in series with a 100 ohm resistor and the diode so the difference in the R DS(on),max has little effect. Jack WA9FVP Willco Electronics - Jack WA9FVP

[Elecraft] Err AT3

Curious little bugger; since yesterday when I turned the K3 on and got a message on start-up saying ERR AT3, I find this happens all of the time now. In this error message state I can not transmit. What it takes to resolve this is to tap on a function switch like band change, mode, split
