Yes and remember, ALL lightning protection efforts and methods must be outside of the house or structure for safety reasons. PolyPhaser systems are noted to be excellent in this regard. And second, the ground system provided for your station must be bonded back to the AC Main ground.T

Re: [Elecraft] K3S Power On / PTT

In this regard and while waiting on my new K3S to arrive, I've read the manual several times. These discussions then raise the question, "is there no Master Reset" that returns the radio to factory default values? I may have overlooked this. However the product not having a Master Reset

Having had a recent loss of radio equipment along with other items, I would comment, the insurance company strongly and aggressively pushed for a settlement under the loss definition of "power surge". In this case they would only pay depreciated value for the equipment less the deductible w

Re: [Elecraft] K3S Power On / PTT

Thanks Lyle. I do have the K3Utility on the computer and will do just that..first thing. As I stated to another person letting me know of the procedure as listed in the manual, coming from other brands of radios that do offer a "Master Reset" I am finding the nomenclature and langua

Re: [Elecraft] K3S Power On / PTT

is not up to your standards. The "master reset" feature is on page 72 of the manual. Elecraft calls it "parameter initialization." I sincerely hope you find the K3S more acceptable after you receive it than you have while you've waited. 73, Scott N9AA On 8/8/15 2:5

Malcolm brings up a very good point. All connections should be fitted with a proper lug which is crimped with a proper tool, depending on wire size and the terminal to which it will be attached, AND all terminals should be soldered.I make no exceptions to this practice.The crimp conne

Re: [Elecraft] P3TXMON question?

A comment here, has anyone thought to use a Bird 43P with a 100 watt HF slug? Or maybe a TelePost LP-100a? Both are equally good regarding power measurements but only when the load is 50 ohms resistive. 73 Bob, K4TAX K3S s/n 10,163 On 8/21/2015 8:15 PM, Don Wilhelm wrote: In a slightly relat

[Elecraft] OT Power Measurements

Seems that I somewhat stirred the pot on this topic with my suggestion of using a Bird 43P or LP-100a.In this regard with a Bird 43 instrument, proper choice of a slug is necessary. Thus if one wishes to measure 10 watts or so then a slug of the proper full scale range, both in power and f

Re: [Elecraft] K2 - KPA100 RS232 interface repair

The K3S has a RJ-45 connector for the RS-232 communications. Now that's different! Of course they supply a cable with a RJ-45 on one end and a DB-9F on the other. And then to keep everybody happy, there is what appears to be a 15 pin VGA connector that is the ACC connector to provide band d

[Elecraft] Different Reflectors for different models

For those that might have a more or less interest in various products. Why not a K3/K3S reflector? Why not a P3 reflector? Why not a KX3 reflector? Why not a K2 reflector? and so on. At least put the model in the subject line. That way I can eliminate automatically the "not intereste

Re: [Elecraft] K3/K3S DB9 Conn - If it plugs in, then it should work

Standard use of connectors is a good thing. It saves the various number of different connectors that we must retain for various uses. However, there is no standards in the ham radio community regarding the use and types of connectors. In the military, they use a different connector for every

If there is a connection which is heating that much, one has more issues than molten solder to be resolved. 73 Bob, K4TAX K3S s/n 10,163 On 8/23/2015 12:37 PM, bs usb wrote: Kenneth Talbott wrote: Never solder PSU connectors - overcurrent can heat the joint and drop molten solder where you

Re: [Elecraft] P3TXMON question?

This seems to have things really screwed up. Yes, the Bird 43 is a 5% of F.S. accuracy instrument. The Bird 43P is somewhat less accurate, although 5% F S with carrier, and more like 8% F S or so in peak mode. In measuring a 100 watt radio with a 100 watt F S slug would seem to be most

Re: [Elecraft] K3S Semi firm plan

I've noticed with my K3S when operating with a SWR of greater than 2.5 : 1 the power output does take a dive downward. While I use an external tuner, it would make sense to have and use the internal ATU in certain applications. While resonant antennas are best, I operate 160M and 80M and due
