It is frustrating for me. I live in rented accommodation on a farm in a hollow surrounded by trees. I cannot sensibly operate from my home location except for Es'Hail.

Fortunately, my landlord and the owner of the farm has a little wooded area that is a bit derelict. He allows me to use this land free of charge with only the simple exchange of me funding improvements at mutual agreement. I have parked a 20' container there and my Strumch 18m mast-on-a-trailer. It is off grid and has no postcode so I do not believe I can make it my main station location and must sign portable. But it is where I go, quite within the lock-down rules, to operate.

For personal reasons I shall not go into this VHF NFD is far more important to me than any other in the past and likely in the future.

I am tempering this by way of knowing that I don't really care about being up there in the tables, and taking part is far more important. I really hope to be operational for this slot, if I can get this damn masthead amplifier to work, and will be one of those shouting "CQ contest, for check log only, just giving away a few points" - which I think it is quite sad.

Doesn't sound like /P operation to me
No different to a shed at the end of a garden.

Nothing to stop you using a generator for your shed power - and it saves all that PME nonsense.

You misunderstand.

If you used the same Vcc for receiver and transmitter when making your test, your result that the audio is louder/clearer when injecting into Vcc could be false.

The other methods (LM317, transformer) will NOT inject significant audio into Vcc,  In both these cases, the audio signal is in series with the impedance of the HB100, so very little audio will have been injected into the Vcc line. .  When you connected the audio signal directly to Vcc with a capacitor, you removed that impedance and superimposed the signal directly into the Vcc line.  

Try this: inject the signal as you did into the Vcc line, disconnect the transmit HB100 ... I suspect you will still hear audio on the receiver.

Re: RSGB interest in bands above 1GHz

Can't help wondering; wear a his vis jacket, perhaps with "JNT Telecommunications" {*}  written on the back of it. and could get away with anything.  Generally, the great unwashed and their minders would show a lot less interest or poke their noses in than if you showed no sign of who or why.

I was at Lane End once with a dish and a chap came up and asked.  I just said I was checking out a radio path.   He assumed I was some company/organisation, and asked if I could fix the telemetry link on the local water reservoir he'd had to come up to read the water level manually.   Regretted "we" weren't that sort of organisation, into repair and maintenance, and suggested he contact a small local RF company I'd heard of. Dunno the outcome, wasn't interested.   It was only a uhf whip so some basic link.   A few years ago I'd have offered to supply a new telemetry system, but frankly, now ....

{*}  You'll have to form your own telecommunications co.

Receiver will be using separate VCC.
So that's not a problem for me for now. But I will keep this in mind anyway.

And even with the other methods (transformator or lm317) I will be injecting audio to Vcc anyway..

There is talk of opening the shops on Monday coming in Wales, I suspect the 5 mile limit will not be far behind. Unfortunately, I am now so far behind with boat repairs, even if they do open Wales up to visitors,  I doubt I will get them done in time for summer sailing, so this season is probably lost to me.  Still, it is doing wonders for the radio stuff, 70cm and 23cm are pretty much sorted, time to start looking at 13cm more seriously ...

Hi Ben...I too struggled with KST and KSTME !

Personally I find that in a contest / activity period, it is like Paddy Market ( Probably can't say that now) However recently I have used it to good effect with Clive GW4MBS to set up 10GHz tests
I see that you too are now on 10GHz and I thing the path to IO80 KX just south of Taunton would be on from your location ...particulary with all the rain we are having of late!

Let me know if you would like to have a go ..I have 5 watts to a 60cm dish ..mast mounted ..I am not far from GB3KBQ 10368.870 with line of sight to the Mendip Hills,,,so a good shot up the Severn valley

7101 - 7120 of 63519
