What a Treat!  Time owned: more than 12 months
I bought one of these at the beginning of my ham career in 1977 at the Rochester Hamfest. I paired this up with my Yaesu FRG-7 receiver and a manual antenna switch. With a 40 metter dipole in the backyard and a fistful of crsytal on the qrp and novice band segments....I was ON THE AIR. As a beginner I could hear more than I worked of course with the lower power but some patience netted me contacts all over the USA. I still have it to this day and its a gentle remimnder of my first experience with QRP that has lasted over all these years.

Excellent Little First CW Transmitter  Time owned: more than 12 months
I owned one of these at the beginning of my ham career in 1977. Used it with a cheap Panasonic SWL radio and a T-R switch. Worked 33 states and 14 countries on 40m CW.. Amazing little XMTR!! Wish I hadn't sold it for $5 at a hamfest! If anyone has one, I'll buy it! 73

Cool, old QRP transmitter  Time owned: more than 12 months
I purchased my MFJ-40T CW transmitter from Hamtronics in Trevose, PA back in 1982. It was my novice station transmitter and I used it with an RCA AR88 and a Realistic DX-160. I made hundreds of contacts with it. It is amazing how much fun I had with a transmitter that cost me 40 bucks and how much could be worked with a watt or two and a simple dipole. I still have it, it still works, and I just picked up another for my back up rig, just in case it dies after 30+ years! Most cost effective piece of ham radio equipment I have ever purchased.

Early vintage QRP transmitter  Time owned: more than 12 months
This little fellow was, as far as I know, one
of the first available store-bought QRP
rigs. Only Kantronics occupied the same
niche back in 1978. Ten-Tec's Argonaut was available
of course but it was the Lamborghini of the genre.

I took it camping to the Bob Marshall Wilderness in Montana.
It's safe to say that this little transmitter broadcast the
first cw ham signal ever from this remote outpost.
It was 2 days in by horseback in order to camp and fish on the
Flathead River.

Sorry. I digress.

2 watts on 8 AA batteries, a companion VFO,
a dipole at 20ft, a straight key----- that's
about it. My receiver was the pricey Sony
Pro80, one of the few handhelds back then
that could detect CW/SSB. The QSOs
were never difficult to find in the early evening
on 7040.

This MFJ transmitter has performed flawlessly
through my camping years.
Wish I had bought two. If it ever appears on eBay,
I'll be on it like a chicken on a June bug.
