M3IIG listening through...

I've only done a foundation license in the UK, and don't have any interest in doing anything higher than that due to my lack of electronics skills.

I take my HT out with me when I go walking among our plentiful (but small) mountains with a local repeater and the calling frequency programmed in. Always handy if you get in trouble.

I mostly do a lot of scanning and SWL with my gear, though, and very rarely transmit.

Anyone else in the UK want to wake up and post?

Just wanted to pimp my HT.



Kenwood F7E. Known as an F6A in America with slightly different bands (ie, has 1.25 meter which doesn't exist over here for amateurs in the UK.)

It's a great little radio and I stuck a new UHF SMA antenna on it and I love it.

I also have a stupidly long telescopic for SWL and low-band VHF stuff, and also a loop longwire that I use for really long wavelength stuff that I built myself.

It's literally a 1 meter length of 50ohm coax with a plug on the end, then the 20 meter loop of wire is soldered from the centre core, then back to the shielding. If you disconnect the shielding end, you can really hear the difference, the interference goes up. The good thing about the loop is that I can disconnect one end, and string it wherever I like, wind it around something to make an antenna for a certain frequency, etc. Crude but effective.

The F6A has a very dedicated following here in the States. I never could get the hang of the menu, as it has a very different feel from my Yaesu, but apparently a great many people have an easier time navigating it.

You must get a lot of interesting signals from mainland Europe. I'm jealous, because we don't get a lot of the cool stuff out here in California. Mostly religious broadcasters (who are responsible for the HF bands turning into poo poo) and a few powerful Pacific Rim stations.

Yeah, I pick up lots of awesome stuff on HF from around the continent. Sadly the HAM usage on UHF is all but dead, and on VHF it's sporadic.

If I'm going to be honest, I passed my licence exam because I thought it'd be cool, bought the radio, and have transmitted like twice in three years. But I do take it whenever I go adventuring in the mountains because it may well come in handy.

I mostly use it for scanning, but it's nice to be able to transmit if needed.

I do get to work with more stuff but thats more or less EHF and SHF which doesnt interest your hammys.

You'd be surprised, there are quite a few people that use the amateur bands up in the gigahertz. Granted, the range is poo poo, but still..

Also, second LF info request :)

There's a VLF submarine station near me, HMS Inskip it used to be called, but nowadays they have a new government agency that handles that, so it's called DCSA Inskip (this is North-West England)

I saw some nice sites that talk about scanning VLF stuff, and they have some nice plots of the waveforms and whatnot.

P.S. PROTIP: With an HT + mag-mount on your car, you can listen to fast food drive-thru window conversations while you're in the line. Drunk/stoned people at 2am = unlimited entertainment.

You probably won't even need the mag-mount, a rubber duck antenna that came with the HT is more than sufficient.

Not when the drive-thru speakerbox transmits on 30 MHz. Why there are 10-meter channels set aside for business use is completely beyond me.

Oh, yeah, that is kind of stupid.

Although, that's range dependent. If you're really close to it it wouldn't be that much of a problem.

Just scan from 240-270 FM and see what happens. Occasionally you'll get military out on manoeuvres, and sometimes pirates piggy backing off the birds.

Or, do what I do, and wait till there's a shuttle mission on. Then you'll get lots of wonderful stations endlessly radiochecking as per the examples here:

http://uhf-satcom.com/sounds/

Rescue birds and ground stations in the US and Europe (TAL sites) are heard.

I wonder if they're allowed to use Marine Band on shore like that.

I mean, sure, you have shore facilities such as ports and terminals and the coastguards using it, but anyone else? They'd be unlicensed, surely, right?

I wouldn't think they'd really like people yapping on CH16 in case of emergencies. Were people moving to a free channel after initial contact or just treating it like a party line?

They very rarely listen to the airwaves because they are so busy. Any contacts are usually prearranged through NASA PAO.

I haven't received the amateur stations, but I have received space-to-ground comms from the Russian Segment on something like 130 MHz.

I'm not sure how much harmonisation there is between countries, with regards to bandplans, so it might not be an idea to try and pick a frequency.

Besides, it's not really good operating practice, is it?

I would suggest using the standard calling frequencies and just using CQ GOON.

Question though. When I put the Icom into scan mode, it stops at a few frequencies on the .00 mark, with some weird noise. For example, it stops at 152.00 every time it goes around. Any idea what it's picking up? For reference, I'm in Summit County, Ohio, outside of Akron.

As mentioned, those are almost certainly pagers at that frequency.

You should get hold of the bandplans and then you'll be able to look quickly.

I've managed to open my local repeater from 25 miles away (tone bursting) with my stock antenna on my Kenwood F7E over 5 Watts. I know that's not really the same as chatting and having readable speech, but at the time I was really quite chuffed.

Found my Kenwood F7e in a drawer at home. Took it into work and scanned across the bands with my best rubber duck antenna attached.

Net result: sweet gently caress all. Everything's on digital now on VHF/UHF, or pushing data over IP to cellular data terminal things. I proclaim the hobby dead (at least in the UK) - obviously there'll be stuff still on the amateur bands but I couldn't really devote the time to checking.

Sad :( Anyone in the UK want to buy my unit? It's modded to transmit out of band too!

I'm currently casually helping a UK friend look into getting his Foundation license.

Apparently UK doesn't do frequency restrictions, but power restrictions? I actually like that a lot more.

Been a while since I did my foundation, but I'm fairly sure there are one or two bands that are off-limits, but they may be experimental bands.

Also you don't get to do RAYNET or anything but lollll

I'd like to sell my F7E if anyone is interested? It's been modded to transmit out of band, which is of course very naughty. But shh. Battery isn't in the best condition but you can get aftermarket ones. It's quite an old radio but very nice and I have a few other antennas to go with it.

PTT button is a bit flakey but if you're using it for monitoring this isn't a major issue :)

UK-based. Anyone? I'm not even sure what it's worth nowadays, eBay doesn't seem to have any for a comparison.

I’ve just bought a pixie kit and I’m having fun building it. I was wondering if the supplied transistors, an S8050 and S9018 would be the best NPN transistors to use? Would I get any better performance with a 2N2222 or something? I know I have to think about frequencies as well.

I’m looking to improve the power output but fully appreciate that I can’t achieve miracles.

Apologies for the 101 question, but I'm trying to find, very simply, the difference between an FM transmitter circuit and an AM transmitter circuit, but everything looks the same and there's less examples than you'd think.

Literally just looking for oscillator, mic, mixer, antenna kinda thing. Is it the way the transistors are linked that determines the kind of modulation performed?

My breadboard circuits don't work also - I am very sad. I know they are poo poo for RF for but basic hobby 30meter range stuff it should be ok. I have no real analysing tools other than a multimeter :(

Reluctant to move to protoboard until I have something tested and working.

longview posted:

Do you have any examples of what circuits you're looking at?

For the extremely simple cases like 2-3 transistor transmitters the modulation might affect both frequency and amplitude, the AM receiver will usually ignore frequency changes and FM receivers will ignore amplitude changes.

Ooh. That’s interesting. I assumed it was the layout of the circuit that did it.

Half an hour calling CQ from a decently-open park in Edinburgh has convinced me that analogue VHF/UHF is dead over here. Everyone up here is all DMR and it doesn’t interest me at all, so I won’t be buying any kit for it.

Anyone else despairing in the U.K. at all? Did I get back into all of this at the worst time? Last year I did SOTA and there are some local folk listening for that, but that’s few and far between.

Maybe 4:30pm on a work day is the worst day to try, I could try one evening I guess.

With the UK dropping the requirement to do an in-person practical, I took the opportunity and I got my my UK foundation license the other week :woop:

Yet to make any contact with anybody, the first (and only) signal I picked up was two dudes talking about their cataracts and disability badges.

Bought a DMR radio too hoping to make a contact with a friend on the coast, but all the Repeaters i can pick up are analog only.

Have parts to make a slimjim antenna on the way, hopefully I can get a bit better signal with that. Otherwise it’s off to find some accessible hills.

Welcome! I’m a foundation too but the RSGB have now said they’ll do intermediate level exams too so I’m highly considering it. I don’t have much practical experience, basically none on HF. Maybe in the future but I’m primarily wanting to do this so I can put my own gear on the air, which foundations can’t do.

I can reliably-ish pass test exams from some app but the current RSGB 2019 mock papers did kick my arse a bit.
