OSCAR 6 1974
Equipped with solar panels powering NiCd batteries, AO-6 provided 24 V at 3.5 W power to three transponders. It carried a Mode A transponder (100 kHz wide at 1 W) and provided store-and-forward morse and teletype messages (named Codestore) for later transmission.
AO-6 had a 1.3 watt transmitter into a half-wave dipole antenna. AO-6's receiver input sensitivity was approximately -100dbm (2 uv per meter) and had an AGC that provided up to 26dB of gain reduction optimized for SSB modulation.
145 up 28 down
and 432 up 145 down
Orbital parameters were obtained by programming an STC mini computer at BCAE using one of these

Re: Remember these?
I think there may be a thread about older calculators, but this was used by me at trade school in the late 70s.
My (Civil Engineer) father upgraded his calculator and I scored this beauty. The photo was taken today
with the displayed result of factorial 69 which was the best it could do. A Windows 7 (scientific mode)
will display the result of factorial 3248 ...fairly useless information but the technology progresses !
I was amazed to find the machine ran for a while after the mains supply was removed - the NiCads are
about 40 years old !

I had one of the first TI calculators , went through college using a slid rule which still functions well and never needs charging offer any problems and is on the money at each useVK5ACY wrote:I think there may be a thread about older calculators, but this was used by me at trade school in the late 70s.

1/2 inch 1962 Birko 60 watts soldering iron.
Purchased by me at Mantons harware East Vic park in 1962.
Sitting on top of a 1980 Milo tin used as a wind shield when on the roof soldering wires or connectors etc.
Remnants of solder dating back to about 1980 in the bottom of the tin.
This iron still works like new and in regular use to work SMD devices in delicate ham stuff.

Re: Remember these?
The most amazing thing is that somebody is still selling them.
And just when you think your "tard-o-meter" is registering a +30, you discover he's sold out of them !
Re: Remember these?
I also have an original box of these little gems in the back shed.
I haven't worked out why outlaw motorcycle gangs are making millions of dollars selling throwdowns to kids.
If you made $1 profit on each box, and how many million children are in this country and could easily chuck a packet of these in 5 minutes.
Not to mention several million adults who'd love to chuck a packet of them.
I show them to friends and their eyes glaze over and their mind is flooded with some good childhood memories.I haven't worked out why outlaw motorcycle gangs are making millions of dollars selling throwdowns to kids.
