Holger,

I was thinking the other day about You saying that You built
a SSB rig in the early 1950's.

I was thinking to myself, was it a Phasing or Balanced Modulator rig?

I'd think You used the Phasing circuit, as the Central Electronics 10A,
10B and 20A SSB Transmitters did.

In the early 1960's I met a Ham in San Francisco, California who would
join in a QSO by tuning his 10A to Zero Beat on an AM'ers signal while
that Ham was talking and other Hams thought he was using AM until he
told them different.

Some AM'er didn't like it a bit.

Back then, was it like that in Europe as it was with some AM'ers in
the U.S.A., like the one Ham I met on the Navy Base that hated SSB with
a passion? And didn't like the Ham using the 10A on 'Their' AM Freq.

When someone used SSB on 80M around the Louisville, Kentucky area in
the late 1950's, no one got excited about it, they just let the SSB'er
do his 'Experimenting' and flipped their Beat Frequency Oscillator ON
so they could hear what was said by the SSB'er.

The Ham with the SSB rig was a Old Timer, who also worked for a 2-way
Radio company as a service technician.
I can't remember what AM Rig he used at his QTH, but I know it sure
wasn't a Heathkit DX-40 like I used. .... ..
Several Hams in the area had built Plate Modulated KiloWatt TX's,
and he may have been one of them, I don't know as I never visited his
Ham Shack.

Which made me want to ask You, does Your License allow You to use
One Kilowatt of Input Power at Your QTH in the Aland Islands?

Oh, another thing came to mind as I was writing.
My first experience using a Collins 32S-1 on CW made me think that
That Collins XMTR was Illegal to operate on CW because it used an
Audio Tone over the Supressed Carrier.
To my way of thinking back in 1961(2?) that was MCW (Modulated CW)
and MCW wasn't allowed on the High Frequency Ham Bands by US Hams IIRC.

GM Ed,

I was thinking the other day about You saying that You built
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 á 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 ---------

I'd think You used the Phasing circuit, as the Central Electronics
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.

Some AM'er didn't like it a bit.

Well, locally I was called Donald Duck but that was all.

Back then, was it like that in Europe as it was with some AM'ers in
the U.S.A., like the one Ham I met on the Navy Base that hated SSB
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.

When someone used SSB on 80M around the Louisville, Kentucky area in
the late 1950's, no one got excited about it, they just let the
SSB'er do his 'Experimenting' and flipped their Beat Frequency
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.

Which made me want to ask You, does Your License allow You to use
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.

Oh, another thing came to mind as I was writing.
My first experience using a Collins 32S-1 on CW made me think that

Audio Tone over the Supressed Carrier.

That has never been illegal here. With a well suppressed carrier the
only signal you hear is carrier.

I looked at the Specs. and Feel in Love with the tube.
I've never owned one of my own, but I did buy a pair of
'pulled from service' 4-125A's at a Hamfest Flea Market years ago,
and never completed the project to use them in.

The most power I've used on HF was 300W but I can't remember what tubes
were in the RF Amp, and I don't have it anymore.

Oh, another thing came to mind as I was writing.
My first experience using a Collins 32S-1 on CW made me think that

That has never been illegal here. With a well suppressed
carrier the only signal you hear is carrier.

To my way of thinking the 32S-1 was running MCW (Modulated CW) which
wasn't allowed on HF frequencies in 1961 IIRC.
To me it was Tone Modulated AM with a supressed carrier and probably
with a supressed sideband.

From looking over the Kenwood TS-520S schematic it looks like that is
how CW is created in my XCVR.

One Terminal from the Key Jack goes to the "AF UNIT" pc board and then
on towards the "RF UNIT" pc board.

Speaking of "Final" Tubes I rembember from the 50's when I was on a
Submarine for the Radar the ET's they had a board with a spare set of
Finals mounted with the filiments powered.
Seems like the tubes needed a break in because of you put a cold set in
and hit them with the high voltage B+ they would fail.

Well, we were allowed 150 Wo at that time in history so this tube was
ideal for the purpose unless you wanted to downspec an 813.

Actually I just sifted through the rules and found that I am allowed to
run 1 kW with my license but as said I've never had the need for that.

That is the way old (even unused) should be broken in irrespective if
directly or indirectly (cathode) heated. The reason is that the glass feedthrough always allow some of the vacuum to escape with age.

When the tube is manufactured the getter is used to burn the remaining
air away but after that the getter is useless. That is the purpose of
the pre-heating of replacement tubes and it also concerns old unused
spare tubes.

the need for that.

300 Watts is the highest RF Input Power I've ran at my QTH, and I think
300W on HF is probably ALL I need to run.

When I had the Home Brew 300W RF Amp, with plug-in coils, a older Ham
Operator built and used years ago, that he gave to me, I made a QSO on
20M CW with a Ham in Katowice, Poland once when I lived 20 Miles South
of where I live now.

I know Katowice is a short distance from Your QTH but it was DX to me.

The only other higher powered TX's I've used was a T350-XM that was
replaced by the CE 100V/600L at K6NCJ when I was stationed at Naval Air
Station Alameda, California.

I loved using both of those TX's.
When I keyed up the T350-XM on 80M or 20M AM it made a 'Hole' in the
frequency I used.

Before I was assigned duty in Alameda I was in Norfolk, Virginia and
used a B&W 5100 at the Ham Shack on the Base.

In the mid-1960's a local Ham Radio Store had a list of Radio Gear it
wanted for Trade In and to my surprise the B&W5100 was at the top of
the list.

I asked why and was told that CB'ers wanted those TX's because they had
a 11 Meter position on their Band Switch and ran 180W RF Input.

That made me wonder about the owner of the store who was a Ham.
