That would have been the 14" model Geoff - the 17" had a higher EHT. If memory serves the 17" version actually used a 30P4MR (the MR was a special version for Murphy as they used one of the octal base tags as a connecting tag for somewgint else as the standard 30P4 had an internal connection to that tag so the trick was to just cut the tag off and replace it with one not connected to the valve base)

On a slightly more bizarre note, we had a very exuberant border collie who always jumped up to greet. One day, he managed to snag a tooth in my wedding ring - it HURT (and left a dent in the rim of the ring for years after).

btw Geoff, monochrome TVs had the EHT at 15 KV (colour ones are round 25 KV) but the problem with watches wasn't the straps  - it was the magnetic field from the scan coils that had me getting a replacement hair spring (in mechanical watches) on average every 6 months if I forgot to take it off laugh. I did get a few zaps from EHT but never due to a ring or watch: one day I had it shoot thropugh from a knuckle on the small finger to the knuckle on the index fingerr (leaving a pinhole sized callous). The standard safety rule was to work with one hand in your pocket so that any discharge would go down one side and not across the chest

Thread: YAD (Yet Another Drone) and its idiot
22/02/2019 00:49:40

Nice thought Steve but I doubt if the Aer Corps has the funds (or the manpower). Their 'strength' (sic) is

2 CASA CN-235 (maritime patrol)
1 Learjet 45 (VIP/air ambulance)
1 Britten-Norman Defender (police support)
5 Cessna FR172H (surveillance)
6 Agusta-Westland AW139 (utility/ASR)
4 Eurocopter EC135 (2 military, 2 police support)
8 Pilatus PC-9 trainer/CAS)

3 Pilatus PC 12s on order to replace the Cessnas

and about 150 personnel

You'd think some people would have sense, or maybe they just feel they can do what they want, where they want

Dublin Airport isn't one of those places

If you just google 'piper cub military' there are loads of images and colour schemes - from army camouflage to naval blue/white and marine midnight blue (and some all yellow and all silver)

We used to refer to that style of crown as 'King's' and the current as 'Queen's'. Correcty, the older style was 'Imperial' which would put it before 1947/48.

When I was an erk back in the early 60s, I had been issued with the current stye of cap badge, but I had my late father's badge (old style) which I wore instead (and never got pulled on it).

The crown design was also on the brass buttons on the best blues and changed at the same time as the cap badge

On a beautiful summer’s day, two English tourists were driving through Wales.

At Llanfairpwllgwyngyllgogerychwyrndrobwyllllantysiliogogogoch they stopped for lunch and one of the tourists asked the waitress: “Before we order, I wonder if you could settle an argument for us. Can you pronounce where we are, very, very, very slowly?”

The girl leaned over and said:

“Burrr… gurrr… King.”

Interesting reference in that referring to the BMFA exemption "...the small unmanned aircraft shall not be a rotorcraft with more than one lift generating rotor or propellor..."

Guess that means no scale Chinooks or Ospreys.

Well I suppose it is the 'best price' (if you're the one doing the selling)

Thread: Ferrite coils.

Surely they are simply RF suppressors that are fitted as standard on a number of ESCs, in fact not particularly aimed at multi motor models use at all.

Yes Pat, that is the normal case but in this instance the guy said his motors wouldn't sync. It's possible that he had an electrically 'noisy' one and that was causing the interference and de-synchronisation

06/01/2019 22:54:30

I'll hazard a guess here and point out that ferrite cores installed like that would smooth out any voltage spikes coming from tjhe other power egg

Thread: Blotto rip-off
06/01/2019 09:24:20

This one claims there are 'no major rips' (well the bottom part of the p[lan isn't there so it's not actually ripped).

Nice price for something with a lot of stains and bits obscured by water damage

It doesn't stop it being insulting Erfolg.

What I'd like to know is what idiot released their details when they hadn't even been charged, vbrought to court or anything else

Yep, we had models known by different colours for different bands for detection and jamming to counter the remote IED threat.

There was a totally unintended side effect there. I always knew when there was a road check ahead by the buzzing on my 2 metre rig (fm only) - it didn't affect the main rig in the shack which was multi-mode.

23/12/2018 09:22:51

Maybe, but during the 'troubles' here, 'jammers' operated on 10.7 MHz (IF frequency for FM superhets) and blanked out not only CBs but also any FM ham band rigs.

That's the usual system - don't hit the operating band, but the intermediate frequency in the receivers and then it doesn't matter what band they are operating on

22/12/2018 12:23:51

The big problem is 'knee-jerk legislation'. Back in the day, during the 'pit bull' saga, the Irish government decided to copy the Brit laws but managed to end up banning ownership of Bull Mastiffs, ALL Bull Terriers and English Bulldogs.

Politicians don't seem to be able to actually THINK first
