Being New Years Eve, it is nostalgia time, and I think it appropriate to 
discuss those antique stations.

If you want to hear how bad some of those antique transmitters were, do 
listen tonight for SKN.
Bad chirps, bad keyclicks and lots of phase noise that spread the 
signals out over a large portion of the band.
The bands today are more crowded than they were back then, and while it 
is legal to use those antique transmitters and receivers, I do not think 
it should be an everyday event.

Yes, I know several hams who are into 'boat anchors', particularly those 
old AM transmitters.  Fortunately, that crowd concentrates on 80 meters 
when the band is not full of signals, but listening with today's more 
selective receivers and hearing signals in a 'net' so spread out and off 
frequency, it amazes me that we were able to communicate easily back 
then.  BUT we did, and had fun doing it.

I would not advocate using those transmitters and receivers in a contest 
today, but they did work for us back then.  BTW, I was first licensed in 
1955, so you can perhaps understand the advances in technology that I 
have seen over the years.  There has been a LOT.

I have often considered building again my Novice transmitter which I 
assembled from the article in the 1955 ARRL handbook (a 6CL6 xtal 
oscillator and a 6146 final), but obtaining the parts is almost 
impossible.  Can you find 1 1/4 inch diameter, 4 pin coil forms these 
days?  Maybe, but they are prohibitively expensive, and the power 
transformer is almost impossible to find although back then, they were 
quite common because they were used in TV designs.

I pass by the flea market areas at hamfests and get enough of my 
nostalgia satisfied by looking at those old transmitters and receivers 
that I drooled over 'way back then' knowing that as a teen with limited 
income I could never afford them.  I don't have time nor energy to 
restore any of those 70 pound radios, nor does my hamshack have space 
for them, so I look and marvel, but do not take any of them home with me.

I do have my homebrew receiver, a version of the HBR-16 and an old NC100 
receiver that I may someday bring out of the attic and bring back to 
operational status, but that is pretty far down on the priority list for me.

Enjoy SKN and listen to those old transmitters (and even listen on your 
vintage receiver).  It is a telling story of the history of ham radio 
and the gear available in the years gone by.

Happy New Year.
