I installed Windows 3.0 for the first time today* From seven 720 kilobyte stiffy** disks. And it worked first time.
* Windows 3.1, I’ve installed countless times. Windows 3.0, never.
** Yea that’s what we call them here.
Found a stowaway in our mosquito net.
I mentioned previously that I figured out how to make a new display for an FT-x90R. My own rig is still in pieces ‘cos I’m not quite happy with the software yet (or actually, with my reverse engineering of the display protocol, but it’s the same thing in the end).
But Dave ZS5DF wanted his rig fixed so I fitted a new display, even though it doesn’t have the
F key “P” priority display function in firmware yet.
Two filament bulbs, because the replacement display needs light from the right-hand side and the S meter is on the left-hand side.
Component cost is close to R500 which almost puts it in good-money-after-bad territory but I like these little radios.
Younger kid had to build an electric motor for a school project. Having a garage full of stuff, it was no hassle to find everything required to build one.
I made her wind the coil.
But the question is, how do kids complete (or even conceptualise) something like this if they don’t have a Wouter around the house?
This is a C1166 Pulse Tetrode made by English Electric, who also made transistors. Good for switching 17 500 volts at 15 amps. But only for 1 microsecond every 1 millisecond (1T4 and AA battery for scale).
The filament alone needs almost 60 watts (9 amps at 6.3 volts).
Quite useless unless one wants to build a glowbug radar or something. But quite marvelous in a way.
Playing catch up. The following two funnies from Kevin.
Thank you for asking.
Background: I think I found a way to fix a broken display on my Yeasu FT-290R 2m all-mode radio. A broken display on these things is common, and displays are very much NLA. The FT-290 (2m), FT-690 (6m) and FT-790 (70cm) are all pretty much identical except for the RF bits, so a fix for one is a fix for all.
So I advertised on swop shop, looking for an “FT-290R / FT-690R / FT-790R”.
Hello Wouter ,
Thanks for the mail. I have the requested FT-290R / FT-690R / FT-790R
in an excellent condition I will be shipping via FedEx courier on a 3
working days delivery and will accept payment via Western Union or
What’s your complete shipping address?
First and foremost before proceeding with transaction we can only
accept payment via western union if you are satisfied with that kindly
get back to me.
Maybe I should ask for a photograph of this “FT-290R / FT-690R / FT-790R”.
