Re: [Elecraft] Receiver Similaritie"

[Brian Denley]

The HRO 500 was my dream receiver as a young guy but unaffordable for a 
teenager.  That one had a digital display and was all solid state.  Around 1967 
or so.  The old building that housed the National Radio plant is still there 
about a mile from where I live.

I racked my brain on this (I had an HRO) and the only thing I can think of is 
that they both have a sort of digital display.

Re: [Elecraft] Receiver Similaritie

[Don Wilhelm]

Doug,

Actually, I have no idea of what you are referring to.  The HRO 
receivers have the large dial which at that time provided good dial 
reading vs. frequency readings.  That was done with a chart of frequency 
vs. dial number, and with Elecraft gear, that is done in firmware with 
the display showing the actual frequency without reference to a graph.
There is a crystal filter in the HRO, but it is not like the filters in 
the Elecraft gear - in those old days, you had to adjust the crystal 
phasing to peak the signal and it was only useful for CW.


I don't know which HRO receiver you are referring to.  There is a big 
difference between them, culminating with the HRO50.  My experience with 
National receivers goes back to the NC-100 which was the predecessor to 
the HRO series, and has the bandswitching system of the NC-240D (I still 
have it in the attic - a restoration project for "someday-maybe", but it 
may never actually happen).

Well, I have owned both of them (HRO-Jr. 1952-64. K2 2006 - present).
Never really appreciated the HRO until it was gone.

Re: [Elecraft] Receiver Similaritie

[Brian & Cyndi]

Hi, Doug!

Two questions...

What do you mean by "technical design technique"? Is this referring to 
how the rigs were designed? Or is this a technical "feature" common to 
all their rigs?


And you are suggesting this technique applies to every model of Elecraft 
radios, from the K1 to the KX3?


Having owned both Elecraft rigs and HRO rigs, I am very curious about 
what you are suggesting.

Re: [Elecraft] Receiver Similaritie"

[Fred Jensen]

Ummm ... my K3 has a tuning "precision" of 1 Hz, repeatable.  It has 
whatever "accuracy" I set when I calibrate it against WWV.


Unfortunately I never had any of the HRO series and only used one a 
couple of time on FD 150 years ago, so I don't know the answer to the 
question.
