[Elecraft] Type 31 Ferrite

I've got a small stack of 2.5 inch diameter type 31 ferrite rings. Interestingly the resistance measured on the ring was dramatically different depending upon which of the flat sides measured. One side 600kOhm+/- whilst on the other 10>20kOhm. This was the same for all of them. Regards,

Re: [Elecraft] Programmable access to KXBC3 clock?

Terje, Setting the RTC from KX3 Utility already is present. It sets the clock from the computer clock time. Reading the clock is a different matter. If you have a computer connected, why not just allow the logger to use the clock in the computer? 73, Don W3FPR On 5/23/2017 7:21 AM, Terje

[Elecraft] Programmable access to KXBC3 clock?

Hi, I’m wondering if it’s possible to get programmable access to reading and/or setting the KXBC3 internal RTC (real time clock), through the serial interface? If not, that would probably make for a nice feature request? I checked the programmers manual and the KXBC3 manual, but I must have

Re: [Elecraft] K2 smeter not showing RF Power

Graziano, I understand the S-meter display is OK, but that is not related to what I was saying. I hate to see you replace the pushbutton and still have the problem. Tap the DISPLAY button and see if it displays the voltage and current. If not, replace the pushbutton. If it does display the

Re: [Elecraft] BL2 -- Antenna Balun Usage

I was going to respond to Jim’s comments about terminology, but Wes presented my thoughts better than I could have. I would like to address two of the comments that were made in the responses. First, EZNEC is powerful tool that can help understand theoretical behavior of ideal antenna systems.

Re: [Elecraft] Transverter Interace Question

Hi Doug Your work around is the way I had to do it when I borrowed one to use a 28MHz IF! I recently asked kuhne if there was a split IF /1mw of drive so I could use the 23cm module with the kxv3b and was told "that option is available with the built option" (ie the 1100 Euro model). For that

Re: [Elecraft] BL2 -- Antenna Balun Usage

Terminology does count, especially in technical areas, like radio. If you ask to borrow my truck, and I say "yes" and hand you my hand-truck (two-wheeled dolly) it's probably not what you were thinking. On 5/22/2017 10:19 PM, Clay Autery wrote: How about not worrying what to call it, period?

Re: [Elecraft] BL2 -- Antenna Balun Usage

Since a truck can be defined as a wheeled vehicle for moving (heavy) loads, many variations exist. Likewise, a balun can be defined as a device for converting from a single-ended to a balanced source/load and many variations exist. The fact that both terms are all-inclusive doesn't negate

Re: [Elecraft] Type 31 Ferrite

This is not unusual. The value is not critical, but rather that the resistivity is within a range that CAN be measured with a typical VOM. 73, Jim On Tue,5/23/2017 5:50 AM, Mike Harris wrote: I've got a small stack of 2.5 inch diameter type 31 ferrite rings. Interestingly the resistance

[Elecraft] KX2 Firmware

Greetings, I was just looking at the KX2 firmware, Beta and 2.69 and discovered that they were built and released in the 11th Century!! Who knew?!? **MCU 2.69 / DSP 1.49, Final Release Feb 5, 1017** **MCU 2.75 / DSP 1.49, April 7, 1017 **Best regards, Tom, W1TEF Lexington, SC ** **

Re: [Elecraft] K2/100 overheating?

Ken, That bias setting is correct. The current draw seems a bit high to me, but may be OK - I do not have typical measurement data. One more check - make sure that Q6 and Q7 are oriented properly. They appear at first glance to have 2 flat sides, but the "round side" has chamfered edges.

Re: [Elecraft] BL2 -- Antenna Balun Usage

Even Jasik, ed., "Antenna Engineering Handbook" mentions the balun. My first ham antenna (1952) was a 40 meter dipole fed with 72-ohm twinlead and a B 1:1 air-core balun and I once worked on an airborn military system which used a balun. The term "unun" has a much more dubious justification,

Hello Don, thanks for the answer. Maybe i did a wrong explanation and the last lines made a bit of confusion. I was intended to say that is normal that when you are in CW, when you press the RF-/ALC button nothing happen and you get only a "BUP-TONE" back ! The problem is the during transmission

Hi Dave, Yes this is the place and that's a great idea. It's called ballistic tuning. I think it ultimately became the feature that makes the RIT dial a rapid tuning dial. Check out the 2009 e-mail from Wayne that I pasted below. Maybe Wayne will update his earlier comment. 73, Mike K2MK On
