Re: [Elecraft] [K3] Err 12v

I recently had Q6 on the LPA board fail shorted, in which case you will get no power out at all. It's a MOSFET and very prone to an ESD event since it is on the antenna. Check gate-to-source resistance with an ohm meter. Should be 800 or so ohms. 73 N7RT - Original Message - From:

You will be better off just buying them new. You will have all the instructions plus guarantees. N7RT - Original Message - From: spitze1 nh...@gmx.net To: elecraft@mailman.qth.net Sent: Monday, December 27, 2010 10:04 AM Subject: [Elecraft] Wanted: Elecraft K3 Options (KAT3 Tuner, 400

Re: [Elecraft] Semi OT: vertical wire antennas

The only caveat I would add is DO NOT end your vertical in the tree. The tree will catch on fire even at the 100 watt level. The voltage potential at the end of a vertical can reach 10,000 volts or more. I have the experience... Instead, attach a U-Bolt with an insulator to extend the

Re: [Elecraft] K3 Questions and gripes

Hi All, I just had my first failure on the K3. I noticed both the AF RF small knobs were slipping so I thought the set screws were loose. But closer examination showed that both knobs were cracked. I replaced them with some small aluminum ones from Radio Shack. I don't think I over tightened

[Elecraft] AF RF knobs

Thanks to all who replied. Apparently this was a quality issue at one time that I was unaware of. I should have checked the archives now that I think about it. 73 Hardy N7RT __ Elecraft mailing list Home:

[Elecraft] VFO A B tracking?

I just noticed when I turn VFO A knob, VFO B tracks along. I can't think of why that would be. I don't remember if it used to do that or not and looking at the manual did not yield an answer. There again I have wasted a couple of hours tweaking this thing and did not get it fixed. I don't think

Re: [Elecraft] Need for advice was; (More Thorough Documentation)

Just my 2 cents on manuals. The N1MM, Logger32, Elecraft, et al all could use improvements. My suggestion is to write comments on the sides of each page (or somewhere), and when you think you are proficient at whatever you are doing, send them to each institution involved (scan, Xerox,

Re: [Elecraft] Re： soldering station

I use a couple of Therm-o-Trac irons made by Hexacon. They are very good for surface mount work. Metcals are good expensive as you pointed out but they produce short range RFI. Hardy N7RT - Original Message - From: w2bvh w2...@comcast.net To: Johnny Siu vr2...@yahoo.com.hk Cc:

Re: [Elecraft] [K3] Overvoltage protection?

To all on the net: I bought an AS35A at a swap meet and so far it's doing it's thing just fine with the K3. But there was no paper work. Are there tests I can do that say yeh verily this thing works as designed? 73 N7RT - Original Message - From: Tom Hammond n...@embarqmail.com To:

I agree with the reply and results that Don got but we are straying off course. Please can everyone who is involved take this thread to Tower Talk? I am still try to learn this radio. 73 N7RT - Original Message - From: Don - K2PMC k2...@arrl.net To: elecraft@mailman.qth.net Sent:
