Sure sounds easier than turning off the plate supply, opening the top
of the cabinet, changing the coil(s), closing it up, turning the HV on again, then tuning the rig for the new band.

You forgot to add changing the coils in the HRO receiver :^)

We are indeed spoiled. If Elecraft could just fix the disappearing of ham bands on the BAND button when tuning to a non-ham-band frequency, I would be happy as punch. Not all radios have a dedicated button for each band (at least 11), which is really a waste of panel space. I have been happy band-switching (up/down buttons) with my IC-718 for years, but it doesn't have the Elecraft disappearance quirk.

Many (many, many) years ago my station consisted of a Heathkit Apache
TX1 transmitter, Mohawk RX-1 receiver, and SB-10 SSB adapter. I figured that I had to switch or adjust a minimum of ---12--- controls to change bands. If I needed to change between LSB and USB, add two more for a total of 14. And that does not include switching antennas and changing the dial frequency if required (on both transmitter and receiver). That also does not include my 6 and 2 meter transverters. In those days I thought twice before deciding to change bands. :=) On the other hand, the SB-10 phasing-type SSB exciter had absolutely WONDERFUL-sounding audio. I got unsolicited compliments on nearly every QSO. Al N1AL P.S. The list as I recall it: TX-1: Bandswitch Tune/operate switch Driver tuning Driver gain Plate tuning Plate loading RX-1: Bandswitch Antenna trimmer SB-10: Bandswitch Carrier null #1 Carrier null #2 Tuning On Thu, 2008-05-29 at 13:33, Bob Nielsen wrote: > You forgot to add changing the coils in the HRO receiver :^) > > Bob, N7XY > > On May 29, 2008, at 1:23 PM, Mark Bayern wrote: > > > Sure sounds easier than turning off the plate supply, opening the top > > of the cabinet, changing the coil(s), closing it up, turning the HV on > > again, then tuning the rig for the new band. > > > > Mark AD5SS > > > > > > > > On Thu, May 29, 2008 at 3:04 PM, David Ferrington, M0XDF > > <[hidden email]> wrote: > >> 5 presses? > >> -- > >> A good cook is like a sorceress who dispenses happiness. > >> -Elsa Schiaparelli, fashion designer (1890-1973) > >> > >> On 29 May 2008, at 20:28, Dave G. wrote: > >> > >>> What's wrong with > >>> "FREQ ENT" -> '1' -> '4' -> '.' -> 'ENTER' > >>> ? > >>> -- > >>> Dave G.

Alan and All,
I had nearly the same setup back in 1961-2 while stationed in Berlin, Germany. Built the Apache, which worked great, then added the SB-10 shortly thereafter. That was my first SSB venture, and you are right--the reports were good. Problem was though, the Apache was not the most stable transmitter ever designed! I had an annoying drift problem, which really gets accentuated on SSB. But Heathkit readily attributed it to a design flaw on their part, and sent me different capacitors to use (temp. compensating). Got the Apache settled down sufficiently (but not 100%), and life was good! Kind of a brick though, compared to my 8 pound K3!

As a 99.9% CW buff, I've not been highly I believe that most, if not all, DSP (i.e. both K3 type and PC type SDRs) SSB modulators are essentially digital version of the phasing design (although note that I am not an ESSB believer). (They might just be third method, but that is still a phasing design.) -- David Woolley Emails are not formal business letters, whatever businesses may want.
