Buying A Second Hand Radio? What Do You Get For £1200?

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!!

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.

If it already bothers my eardrums a little, imagine if I were there lol 😂😂
Glad the vacuum cap isn’t too expensive. Probably be a bit much with shipping. Im in over my head. Maybe i can do a fixed frequency. I have just the frequency in mind too. A guy that jams up the airwaves 24/7. He’s really far away. Itd be so cool to finally make contact. Local doesn’t count to me.
1.5KW!!! Bro! Im happy to get 500! For the price of amps! I just want CB.
Can we make a HV regulator with tubes? I don’t want to use silicon if I can avoid it.
Not using vacuum relays. Looked em up and it hurt LOL. They are beautiful tho. I hope I get to play with them one day.
Not the best but cheap easy and robust. I spent 230 bucks to get four. I wanna make a nasty powerful amp
I really like my SDR rig but i won't give up my old superhet rigs. I have two fantastic old Kenwood TS-850s rigs ,talk about morse machines! I have all the mechanical filters in one of them, and they still hold their own against modern rigs...
Cool to see the red hot turbine.
Tease! 😂
Splendid! Plenty of volts there 😎

Dommage, maintenant Airbus
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.
