[Elecraft] Are the internal 2m Transverter and the external XV144 the same internally?

Are the internal 2 meter Transverter and the external XV144 the same internally? Is it the same board in each? Same logic but different board layout? Adjustment differences? Thanks, Jim KG0KP __ Elecraft mailing list Home:

[Elecraft] KX2/KXPA100 Drive Power

Since I'm basically a QRP op and rarely use more than 25 watts, I guess I didn't notice when this "problem" actually began. So here's the issue: My KX2 will show the power I've set with the knob precisely, right up to 110 watts.  However, my KXPA100's green LEDs seem to be about 20 watts

Don't you think being "rather disappoint[ed]" in the internal sound card is a bit demanding?  Do you really expect a 192 kHz, studio grade DAC internal to the radio? I understand the desire for low noise and wide bandwidth... I do.  But to put a Focusrite Scarlett grade sound interface internal

Thanks Christopher, compared to high quality external devices SNR and THD+N is rather poor. And so is the dynamic range and the max. sampling rate of just 48KHz. Rather disappointing, to be honest. 73 Udo, DK5YA Am 20.09.2017 um 00:24 schrieb Christopher Hoover: The circuit is based on

Re: [Elecraft] Question for Wayne about your OCF Dipole

A couple of points. 1)  In an OCF the currents are not equal. 2) The two cables are operating in a (different and largely unknown) mismatched condition. Using ARRL publications for calculating additional loss due to mismatch is fraught with danger. As is I might add, using older versions of

Skip, Download the older version if you do not already have it on your computer. Then point K3 Utility to the files on your computer, and load the files to the K3. That is all there is to it. Similar to loading beta firmware. 73, Don W3FPR On 9/19/2017 1:56 PM, Fred Jensen wrote: I need

Re: [Elecraft] Question for Wayne about your OCF Dipole

They're in series when used in the manner being discussed, not parallel.  If you were to connect the two center conductors together and two shields together at each end, they are in parallel.  In such case, the shields go to one side of the dipole and the center conductors to the other side.

Re: [Elecraft] Question for Wayne about your OCF Dipole

A few years ago, at a previous home with 5 ac, I considered an 80m full wave horizontal loop fed with ladder line (450-ohm) but coming thru the house wall would require hefty insulators so I considered running parallel coax as Wayne described and have an parallel tuner on the wall.
