   Re: Your First SSB XMTR

   In a message dated 06-13-14, Ed Vance said to Holger Granholm:   
      
   GM Ed,   
      
   EV> I was thinking the other day about You saying that You built   
   EV> a SSB rig in the early 1950's.   
      
   Correct, this is the SSB history of Finland and the Aland Islands:   
      
   History Starts here ......   
      
   I have been licensed since 1951 and operated CW, AM and NBFM prior   
   to the SSB era.   
      
   I started the SSB era as OH2OJ in Finland 1955 by building a phasing   
   exciter similar to the Central Electronics 20A using the PS-1 phase   
   shift unit. The outboard VFO came from a BC-458 surplus transmitter.   
   With this rig I came on the air on nov. 26th 1955 as first OH on SSB.   
   In 1956 I built a Sideband Slicer   la Central Electronics as an   
   addition to the Geloso G-207 receiver and also a 150 W Power amplifier   
   with a 4-65A tube.   
      
   1957 I built my second SSB transmitter, the "Cheap and Easy S.S.B." as   
   described in QST by W2EWL in the march 1956 issue. Also a phasing rig,   
   built on the chassis of a surplus BC-458 transmitter with only the VFO   
   and PA tubes remaining. The AF phase shift unit was a B&W 2Q4.   
      
   The receiver for this station was a surplus BC-453 receiver with an   
   outboard 14 MHz converter. I used this station to put OH0 on the SSB   
   map as OH2OJ/OH0 in the summer of 1957.  The same year in november I   
   moved permanently to OH0.   
      
   END of history ---------   
      
   EV> I'd think You used the Phasing circuit, as the Central Electronics   
   EV> 10A, 10B and 20A SSB Transmitters did.   
      
   The first SSB exciter/transmiter used the CE Phase Shift Network and the   
   second used the B&W 2Q4 Phase shift network.   
      
   EV> Some AM'er didn't like it a bit.   
      
   Well, locally I was called Donald Duck but that was all.   
      
   EV> Back then, was it like that in Europe as it was with some AM'ers in   
   EV> the U.S.A., like the one Ham I met on the Navy Base that hated SSB   
   EV> with a passion?   
      
   Most stations i was talking to were americans stationed in Germany after   
   the war. Some early SSB starters in various countries were also worked.   
      
   EV> When someone used SSB on 80M around the Louisville, Kentucky area in   
   EV> the late 1950's, no one got excited about it, they just let the   
   EV> SSB'er do his 'Experimenting' and flipped their Beat Frequency   
   EV> Oscillator ON so they could hear what was said by the SSB'er.   
      
   I remember that I used the idle carrier of Radio Moscow on 40 meters   
   during some contests. There was no program sent during the night.   
      
   EV> Which made me want to ask You, does Your License allow You to use   
   EV> One Kilowatt of Input Power at Your QTH in the Aland Islands?   
      
   Well, I could update my license to 1 kW by just requesting it but I've   
   never felt a need for it. 100 - 200 Wo has always been enough and pse   
   remember; being in a rare country ups your signal several db.   
      
   EV> Oh, another thing came to mind as I was writing.   
   EV> My first experience using a Collins 32S-1 on CW made me think that   
   EV> That Collins XMTR was Illegal to operate on CW because it used an   
   EV> Audio Tone over the Supressed Carrier.   
      
   That has never been illegal here. With a well suppressed carrier the   
   only signal you hear is carrier.
