Try sticking the question on the RSGB Technical Groups IO (or whatever it’s called).

I have just thumbed through the SBC booklet that came yesterday with my 2022 Rates letter (it MUST be a quiet Sunday morning!!)...

They announced a scheme (page10) to support the installation of solar panels to private houses later this year.

Has anyone got solar panels, have good relations with neighbours with solar panels or who are involved in the industry of manufacture or installation of these (and their control gear) and who can comment on any QRM issues ?

Rob G4XUT has had them for a number of years as had my father G3YCH, not aware of any QRM issues in these instances but I am sure there will be some.

Re: GM3SEK - Clean Up Your Shack - Mains Filter Build Cost

I built one of these filters last year and can confirm that my noise level reduced by a couple of S points across 80-30 meters.

Well worth the money and time..

[Edited Message Follows]

Hi All,

For those that attended the excellent video talk 'Clean Up Your Shack' by GM3SEK on Thursday and for those that didn't, I thought I'd price up the cost of making one of the mains filters. The pricing includes everything, except the 13A Socket Strip as most people are probably already powering their kit via one of these. All the parts can be purchased from just 3 suppliers, Mouser, CPC and Screwfix (for the mains cable). Mouser are able supply both the types of ferrite cores and the Schaffner mains filter. They offer free shipping as do CPC. For the 13A 3-Core cable, I chose Screwfix, as they are local and I can pick up the cable direct from them. I also chose a 10m drum as I'm planning to make 2 filters, so will need at least 6m of cable, so it makes sense to buy a 10m drum as I'm sure I'll use the remaining 4m for another project.
To make 2 filters, the total cost of parts, delivered would be £127.74 (including the 10m drum of cable), so if you half that, then the cost to make 1 filter would be around £63.87. So, if you bought just enough cable for 1 filter, it would probably cost you about £60.

All the individual links to the parts are below:

Correction. Cyril was G1ZGT not G3.

Thanks Tony, I think I’ve sorted both rigs now whilst half listening to the club net on WH! Found the IC706 the toughest to get my head round. Hope to be up Thursday, Bob

Listen on the high frequency and TX on the low.

All,

Please note that the frequency of the Swindon 70cm FM Repeater, GB3TD will be changing on Sunday 20th February. Details below.
As with the last frequency change, the club will be holding a 'bring your radio in to be reprogrammed' evening up at the club, so anyone struggling to reprogram your radio can bring it up the club and we'll attempt to do it for you. Last time we did this, we only found one 'odd-ball' radio which we couldn't reprogram using CHIRP. Keep an eye on the club programme on the website and the weekly email for details.

The change has happened and the repeater is working..

Your Radio should be receiving on 438.3875, TX on 430.7875.. 

It confused me yesterday as I had a positive TX shift where it should be a negative shift

To endorse all that’s said about Cyril, nice he is remembered as he was a great encouragement in years gone past. His antenna was still mounted on the chimney last time I drove by and had time to look! Now, how about Gray ‘KBN who used to reside in Rodbourne, also silent key a similar time. Somewhere I still have recordings of a few QSO’s. Bob G0VTA

Well Marc, following your enquiry, herewith FYI....

Cyril  was a "true" TV engineer - at a time when PL509s and 90° CRT TVs 8n wooden cabinets ruled! 

He was the workshop service engineer for a Swindon TV Sales and Service company. (...diagnosing and repairing to component level long before modular boards were the rage)!

Licenced as G3ZGT (iirc), Cyril monitored WH practically all day - more so after his eventual retirement.

If someone put a call out "listening through WH " he would likely be the first to respond.

Way before the days of Satnavs, if a /M amateur from out of the area popped up looking for somewhere in Swindon, Cyril would talk them in. His knowledge was vast. He would engage the amateur in real conversation en route and, having established where they came from, would chat knowledgeably about their part of the world with ease. Wikipedia had nothing on Cyril's knowledge!

He lived locally until he went SK around the early 2000s??? (Someone will no doubt feed in the actual year).

His 2m aerial - an X50 collinear mounted on the chimney of his County Road QTH  was all he used. But use it he did. He popped up everywhere! Some thought the metal Stand across the road at the football club made a huge reflector for him, but he really did get out.

I recall one day when I was holidaying in West Wales, I put out a call to the local repeater - probably CM or UP - that neck of the woods anyway, and who should reply? ... you've guessed right - Cyril ! from home !!

A fine, friendly, cheerful and very knowledgeable fellow -  sadly with us no longer.

Re: DX Commander - VHF Height vs SMeter Video

Tony (G4LDL)
 

Yes of course height helps cos it gets signals out & back over local obstacles.     To me it would have been more interesting if it had been done in the middle of a big flat field with no immediate obstructions and similar terrain in each direction.

That might have been surprising – who knows!

Yes, I watched that last night. Heavy breathing test calls on all the repeaters ... he must get some exercise and get fit. I think he was quite impressed with 3WH, shame there was nobody there to answer him. I may end up doing the same experiment soon, quite interesting, if a bit predictable.
