OK, odd question

Something that bugs me just a tiny wee bit.
So, for years I used a Kenwood or two, then a Yaesu or three, then a Ten-Tec. Much of the time on CW. When I tuned a band, say 20M, I would start at the bottom of the band and tune upwards in frequency. When I did this, as I approached a CW signal it would be higher-pitched. As I tuned it to zero-beat with my 500-Hz CW offset the pitch would drop until it matched my 500 Hz spot. If I tuned too far, the pitch would drop below 500, then drop off the scale as I tuned past it. Similar in fashion to tuning a USB signal. My Elecraft tunes similar to one other rig I have owned, an iCom 706 MkIIG. As I tune up the band I first hear a low-pitched CW signal, then it centers, then it gets higher in pitch. Similar to tuning an LSB signal. This doesn't make a difference in usability, I guess it's due to the receiver architecture. And, yeah, I can go to "CW-R" and it works the way all those other radios did. My question is, is there a reason for it working this way? Does it provide some advantage? Or is it just the way it happened. like, not enough room towards the edge of the napkin when it was drawn up?

IIRC there was no "standard". It was an arbitrary choice by the manufacturer
which side of the filter they put the BFO crystal frequency. Nice to have a choice with the K3! 73, Roger On 2/14/2018 11:15 AM, Chuck Chandler wrote: > Something that bugs me just a tiny wee bit. > > > > So, for years I used a Kenwood or two, then a Yaesu or three, then a > Ten-Tec.

I for one like the tuning direction of the Elecraft rigs in CW (LSB).
When I began ham radio using much older receivers, I liked listening with the BFO set to LSB. My perception was "If the pitch goes up, I am tuning to a higher frequency". Those receivers did not have very good frequency resolution and it helped me in tuning correctly. I realize that is my preference, others like it the other way around. It is easy to set the Elecraft gear to CW reverse, and that is "sticky", so you only have to change it once for each band. It is a designer's choice, so I guess Wayne agrees with me because he made LSB CW the default. 73, Don W3FPR On 2/14/2018 11:15 AM, Chuck Chandler wrote: > Something that bugs me just a tiny wee bit. > > > > So, for years I used a Kenwood or two, then a Yaesu or three, then a > Ten-Tec.

I find it helpful to tune from a high pitch to a low pitch. That way, I
hear the signal coming rather than have it sneak up behind me and tune past the optimum tone. That means, I have to shift the Reverse function depending on whether I am tuning up or down in frequency.

It is the "custom" for CW mode to use LSB on the bands below 20 meters and
CW USB on 20 meters and the bands above it. Hiram Percey decided that long ago. 73, Roy K6XK I for one like the tuning direction of the Elecraft rigs in CW (LSB).
