Converting An Old WW2 Aircraft Radar Into An Oscilloscope
Instead of putting this vintage WW2 Nav/Radar display unit on the shelf of shame never to be used again, I thought it would be a good idea to convert it into an oscilloscope for the shack

Просмотров 1,3 тыс.5 месяцев назад
If you're in the market for a new rig what sort of second hand radio can you get for about £1000-1200? I compare my recently acquired 2nd hand Ft1000MP to a modern FT710 which costs about the same........

Defender Mods Part 2 : Frontrunner Roof-rack Is No Match For The British Weather!!
Просмотров 30811 месяцев назад
The double-DIN unit is now in and working. I've removed the Frontrunner roof-rack; a bit disappointing to see that is has not survived the British weather that well.If you plan on buying any Frontrunner stuff throw away the rubbish nuts and bolts it comes with and replace them with stainless steel hardware.

There is printed on a A4 paper something like used on a BC 221 frequency meter giving the frequency read out for the HRO. Some time ago I found the chart on the net published by a G4??? but it seems to have been taken down.
Thanks for posting! I just bought a Lightning Bug from the 50’s or 60’s from the son of a Silent Key. Looking forward to building an oscillator to practice it!
Well WTF! I was unsubscribed from your channel! I love 160 and I run a 700' loop that is currently up about 50' in the air. It works pretty well for reliable communication with most of the central USA. I am located right in the center of the country pretty much. My dream is to get a dipole up at least 200' in the air for a dx antenna as I don't really want to put a ton of copper in the ground. 73, KF0BBU.
Hi I’m considering this rack for my 90. Would you still buy one given everything you’ve discovered ?
I think they are good racks but I would just replace the nuts and bolts with stainless ones
The most amazing turbojet engine ever made!!!
Product doesn't work for me. Maybe for somebody else, so that makes it not practical to sell.
I bet his neighbours love him also your channel is awesome
I have a d3 black edition, it's working excellent but two buttons broked...do you have a solution?
nice how those bushes get blasted at 100% N1... love it...imagine mounting a GE-90-115B1 Engine on there... that would be awesome...
Top band dx-ing is something I love most but unfortunately I have no space for an antenna for 160m... 😢
Using an Broadcast sound processor for CB, is the most STUPID thing i ever seen till today!!!
Not CB my clever friend!
My friend has a FT-710 and i listened to his audio on AM mode, but the quality isn't good. Can you show the menu settings to achive a good quality as you shown on this video?
Hi , I cant remember exactly but I think I had the mic gain about half
Nice build
Ouvi transmissão am de um amigo com o ft710 em am o áudio esva baixo . Vc fez alguma alteração no seu tx pra ficar bom em am ? Obrigado 73
Did not see one piece of fire fighting equipment or did i miss that? You must have a lot of confidents in starting and engine that has mot been run decades. Oops did some fire bottles on the ground to the right. When was the last time they had maintenance on them and tanged. 3 nasty bottles most likely not serviceable, at 6:46
Yes they do work and we’ve got the garden hose😂
I understood that the 'B' set had to be decomissioned before they could have been sold as surplus. Looking at adverts in old magazines shows this too. I was told this by the late & legendary Nev Kirk, G3JDK. The B set was what they called UHF back then & this set covered 229Mhz to 241Mhz, which as you know isn't an amateur band in the UK. Richard, G0OJF, UK
j'adore cet avion !!
Any idea where we can get a surplus 2D94-2 PC20 cylinder head?
No idea… Japan?
Did you move the GU50s around to different sockets to see if the red glow traveled with the valve or if any GU50 in that socket glows red? That's the first troubleshooting step, to make sure there isn't a problem with that socket or that channel's wiring. ;)

Where do you get this crap? This uses AM modulation onto a pentode grid. Will need to set 50% power with negative bias on 3 grid then it works cleanly.
Thats more or less how it works… suppressor grid modulation; not very efficient!

Hello Justin! How you make signatures on the front panel?
Hi, I used a Brother label printer. Nothing special!!
As you say……you don’t know much about them.
Everyone needs a jet engine in his backyard
Nice he asks "Dave" is that you? Haha Yes mister that's me !!!
bit late to the party...but change the cap across the meter.....common issue on these...still have mine working great with oem transistors...
Could something like this be achieved with larger ceramic piezo transducers? I found some of them working at around 2Mhz. I see here you're using 8.2Mhz... I'm curious to try this concept on something larger like a garden hose
Very sad to see
His call is G3SES, not SIS. de K4TO
I'm pleased to see how you've set the horizontal and vertical scan amplitudes (a reasonable compromise for the screen shape). But back in the day, sets were always set to overscan - no black visible at all - which always irritated me, as I'd rather have a (slightly) smaller picture but at least see all of it!
Thank you sir for the inspiration! Have you drawn up a schematic for this power supply and amp? I sure would love to have a copy. I am busy studying EX8A's translated webpage for information too.
Too much noise! Needs a major redesign !
Great video 73 de Gerald PA3GEG
Lads that would fit in my car. Just need an rpm step down and tough transmission and am literally away
Use lantern oil
Could I have the details please
I will chime in with other commentators by saying " THANK YOU " for making this video. I is always Great to see these Old Vintage Transmitters and Receivers in Action. For me this is part of which what makes the Hobby of Ham Radio so interesting.
Amazing
That is VERY cool!
2W is really low for those tubes. In 1920 they had housing on their gear.
That's great did similar stuff to.
Where is it?
My favourite airliner
Used to work on these in the RAF, only came here for the sound!
I was cringing the whole time you were poking that screwdriver around on the front panel.
Why does this TRF have so much crackly noise? If the noise source is the antenna or local switching device radiation, can one or more broadband filters be strategically installed to eliminate this noise?
Still no nozzle fitted. Does the spey have reheat? It looks like it did at some stage I have M701 mounted in a pickup truck And a T62 with gearbox for my next project
"Old men talking crap..." Yes, heard on 160, "Jimmy put up a tower a few years ago and he only put a guy wire on the east side because the prevailing wind was always from the east. Well, it stayed up for a couple of days, but then one day the wind changed coming in from the west..." And other tall tales.
