Power cut!

It went off at 11:38. SSEN say they’re aiming to have power restored by 23 Jul 2020 14:30. Normal service will be resumed a.s.a.p.

Shows live again

After several weeks of just pre-recorded shows, a knock-on effect of the first phase of coronavirus issues, we're back with live production. Listeners to Argyll FM on 106.5, 107.1 and 107.7 (which covers most of Argyll on the west coast of Scotland and reaches parts of Northern Ireland and Ayrshire) can again enjoy my Folk At Five shows daily at 1700 Mondays through Saturdays, and Teatime With Trevox at 1800 on Fridays.

There's a lot of new music to hear, added after audition to the playlists which can be checked out on the web by following the links at trevox.uk. Many broadcast shows are also available there to listen to again.

Change of gearbox pro tempore

The lockdown triggered by the pandemic of Coronavirus Covid-19 continues, meaning that my radio shows are using a pre-select "gearbox" rather than the usual live manual, to use a motoring paradigm. It's not an automatic though, so new music continues to be added to playlists. Thank you to all the artists sending tracks in.

Coronavirus Covid-19

In common with many organizations just now, my radio program production has been disrupted. Hope to be back soon.

Music old & new, & sometimes a surprise or two

The daily Monday to Saturday folk music show Folk At Five is produced and presented live in Campbeltown for Argyll FM by Trevox, along with Friday's Teatime With Trevox. After each show, people can listen again on Mixcloud as well as catching up on the playlists with the programmes' 'blogs. Playlists go back years.
Listen live on Argyll FM from 1700 on these frequencies: 106.5, 107.1 & 107.7.
The tagline "Music old and new, and sometimes a surprise or two" is lived out daily in both the social comment, history and joie de vivre of Folk At Five and the dancey feelgood rhythmic records of Teatime With Trevox. New music is frequently added from the plethora of offerings of musicians the world over, and thanks are due to those who send in new material and re-post our 'blog entries on theirs.

Saying goodbye to Windows 10

... goes the arresting heading printed in Which? Computing of October 2019. Probably a misprint, as the article is all about switching from Windows 7 to 10. Check out the online version, informative and minus that error.

Music to the ears, or deafening noise?

A question on Digital DJ Tips in September 2017 went thus: "How Many Watts Per Person Do I Need For DJ Speakers?". Well...

Any 'rule of thumb' relating loudspeaker wattage to audience size is either wrong or at best an over-simplification! Wattage alone does not provide quality or loudness. A set of ground rules for loudspeaker power is proposed below, but first some basics.

People absorb sound and generate alternative sound. Hard surfaces reflect sound. Loudspeakers have varying frequency-dependent efficiencies. There is a helpful noise chart at Noise Help. It indicates that human ears can tolerate exposure to 91 decibels for up to 2 hours. This is a reasonable maximum.

Loudspeaker specifications should indicate their sensitivity as sound pressure level (SPL) in decibels (db) measured at 1 metre with 1 watt applied. (The range of my speakers is 88-98db.) Doubling the wattage increases SPL by 3db. Doubling the distance to the listener decreases SPL by 6db. The critical distance is between speaker and furthest listener.

Rules

1. Minimize the sound absorption of the crowd by positioning mid- and high-range speakers well above head height and angling them down to point at distant head height. That ensures loudspeaker sound can travel direct to audience ears and not be baffled by bodies.

2. No matter how loud the crowd noise is, the SPL at their ears should not exceed 91db. We can use  Geoff The Grey Geek's calculator to determine RMS speaker power for various distances (see table of results for common distances below).

3. Always check sound levels with a Sound Level Meter.

Alesis Monitor One Mk2 Passive (studio)

Distance	Power	SPL
(m)	(w)	(db)
1	1	88
5	100	91
10	398	91 *
15	896	91 *
20	1592	91 *

* N.B. Maximum power for speaker exceeded massively!

Wharfedale Titan 12 Passive (mobile PA)

Distance	Power	SPL
(m)	(w)	(db)
1	1	98
5	10	91
10	40	91
15	90	91
20	159	91

Maxima for Titan 12s

Distance	Power	SPL
(m)	(w)	(db)
10	251	99
25	249	91

Ensure that the maximum power rating of loudspeakers is complied with! If greater distances than these are required, additional loudspeakers would be better than more powerful ones, as the objective is to provide music and not deafen the audience!

Fake Facebook reviews

There's such a lot of fakery about. With fake reviews adding to the dangers of fake products, it's very hard to avoid it. Facebook is still at it, according to Which?, who say :

Surprise, surprise. Facebook continues to be plagued with fake review groups even after a warning from the Competition and Markets Authority (CMA).
These groups recruit people to write fake or incentivised reviews, with sellers offering free products in exchange. It’s deeply concerning that the company continues to leave customers exposed to poor-quality or unsafe products boosted by misleading reviews.
It has been over a month since the CMA told Facebook about the groups that it had found, but our researchers have joined 10 of these Facebook review groups and found more than 55,000 posts over that 30-day period.
Facebook has failed to stamp out the problem and now must take serious action to crack down on fake review groups thriving on its site.
We want to know: have you ever read an online customer review for a product that you thought was a fake review?

Printer not working? This checklist may help.

Support folk helping you with printer problems will probably ask these questions:

A. Printer hardware

1. What is the make and model number [e.g. HP LaserJet P2055dn, Canon MG5450, etc.]

2. When did it last work OK? [minutes / hours / days / weeks ago / never]

3. What significant events have occurred between then and now? [e.g. Printer moved, lightning storm, power cut, coffee spilt, computer (re)configuration]

4. Are power and data cables correctly plugged in and fully home at both ends?

5. What type of data cable is in use? [ethernet / USB-A / USB-C / parallel / serial / localtalk / firewire - see below for details]

6. After switching it on, what lights are showing on it? Please indicate color and whether flashing or steady.

7. Is a print server (a type of network device) in use? [If "yes", please perform checks 1 to 6 above for it also. There will be at least one data cable connecting the printer, a second data cable going to a wall data outlet or network hub, and a power cable.]

B. Computer side

8. Is the problem general for all applications (e.g. SketchUp, Office, MySQL, Adobe Reader, LibraOffice, Draw, etc.), or specific to one of them?

9. What indications or messages show? [you may be able to take a screenshot and email it, describe the indication, or just write down the message]

10. Are there oustanding print jobs in the printer queue? [you can determine this by double-clicking on the printer's icon in Control Panel, Printers] [None, or 0, is normal.]

11. Can you print a test page?

To print a Test Page in Windows 10

a) Click on the Start button, then the Settings icon (looks like a cog, on the left of the screen).

b) Click on Devices in the settings screen displayed, then on "Printers & scanners".

c) Hover over the name and icon of the installed printer to be tested, click to see options, then choose Manage.

d) Click "Print a test page".

To print a Test Page in Windows 7

a) Open Devices and Printers [click the Start button then click Devices and Printers on the Start menu]

b) Right-click the printer you want to test, and then click Printer properties.

c) On the General tab, click "Print Test Page".

To print a test page in Windows XP [your login must have the Print permission]

a) Open Printers and Faxes [click Start, click Control Panel, click Printers and Other Hardware, and then click Printers and Faxes]

b) Right-click the printer you want to test, and then click Properties.

c) On the General tab, click Print Test Page.

d) Click OK if the test page printed correctly. If the test page did not print correctly, click Troubleshoot to open the Print Troubleshooter for help resolving the printing problem.

Like listening to a good yarn?

On Folk At Five I've enjoyed being able to include the serialisation of local author Alexander Weir's tale "Archie & The Dark Door Mystery". An episode concludes the show most days in May and continues into June. Listen again to the shows on Mixcloud. Check out the post-show playlists at www.trevox.uk.

Plastic in our rivers

And at the bottom of the Mariana Trench.

​Greenpeace is testing our rivers in the biggest plastic survey in the UK. Just last year, up to half a million plastic particles per square metre were found in the River Tame - we can’t let our rivers become plastic waterways.

Will you sign the petition to tell government to protect our air, soil and the rivers that connect us in the upcoming Environment Bill?
