[Elecraft] K3 / K3S Filters Available

In a week or so I will be getting my K3S back from Elecraft service where I sent it in for updating. While it is there, I am reconfiguring the crystal filters and will have the following available if anyone needs one or more: Two each 2.7 kHZ OEM SSB filters; list 139.95 sell 100.00 each;

I’m just surprised it took this long to hit 10K. Remember the night they opened ordering? Ye gads that was mayhem. But good mayhem :) I ordered the kit so mine is S/N 267. Great ancestry indeed - the two K2 and two K1 I built were the highlight of my kit building experience. Sorry

Re: [Elecraft] Just RX'd KX3 Serial No. 10,028!

We know that the K3 sold nearly 10,000, so add in the K3S sales, and that is more than the KX3. ICOM sure sold a lot of the IC-706 series. I would not be surprised to see that at the top of the list. If we are talking rigs made specifically for amateurs, the Collins S-line might not qualify.

Re: [Elecraft] Lightening damage

Hi Peter, Sounds like we have a similar setup for lightning protection. I wound up using 23 ground rods all cadwelded together with solid #4 copper wire. Everything coming into the house and leaving the house is all tied together to one point common ground. I never disconnect and most of the time

Re: [Elecraft] Lightening damage

Likewise - 3 direct hits to the tower and nothing in the house damaged. Radios always plugged in. Do it properly (don't trust me - google it). Lots of buried ground rods and copper strap and a single point of ground connection for the radio bench (only). Gas arrestors across all the aerial and

[Elecraft] Lightening damage

Bingo! Of course the tower is not immune from lightning. Mine has taken many direct strikes and it has a number of ground rods. The ground system gives it a path that is not though your equipment. Also a single point ground and proper bonding as K9YC mentioned will keep everything at the same

I supported myself at university as an engineer at the only TV station in town.  Transmitters [10 KW visual, 5 KW aural] and studio were in a building at the base of a 400' tower on a ridge overlooking town.  Studio wiring was in trenches in the concrete floor covered with fairly heavy steel

As a young Naval Aviator, many of my elders, including one commanding officer, were former LTA pilots. God forbid one should utter “blimp.” They used to refer to “lightening,” which was one of the ways that they could get rid of ballast to lighten ship and avoid plunging to their deaths. So

Re: [Elecraft] Lightening damage

It doesn't. But having the grounded tower helps bleed off the charge building in the atmosphere in the immediate vicinity, greatly reducing the likelihood of the charge reaching a high enough level to ionize the air and produce a major lightning discharge. Once the air ionizes it becomes a good

Rich, Even massive grounding systems do not keep a tower from being hit! It only mitigates the damage. I was CE of a TV station in South Florida with towers of 1,000' a couple at 500' and several more at 100' to 200'. They all got hit at one time or other. Sometimes many times a year. We used

Not quite on the topic but FWIW, I had Delta Products Surge units installed at the A/C line coming in to my shop. Both are grounded and then tied between the hot & neutral lines. Fairly inexpensive and somewhat of a "whole house" surge arrestor & protector. They are made by a very responsive

Thanks to all of you for your responses. My need for a lower impedance parallel line is not so much a matter of loss but to minimize the impedance transformer effect a 25’ window line (400 ohm) has when terminated in a low impedance load. My real concern was for the ability of the line to

[Elecraft] Off topic feedline question

My 80M antenna is a low, loaded dipole fed with balanced window line.  As the center impedance is  low the high impedance window line tries to invert the impedance to a much higher value.  The feedline is only 25' long and terminates in a 1:1 balun which is then connected to a remote autotuner

Re: [Elecraft] Lightening damage

I worked in Broadcasting for over 55 years. It’s common for broadcast towers/antennas to take direct hits. The lightening protection systems deflect the energy to ground. AM stations use ball gaps at base of each tower. In the mid 70s I worked at WKBN and lived in a farm house in the middle
