Drivers - NOT amateur radio

Some of the most courteous drivers on UK roads are women.

I also note the high numbers of young women drivers who seem to take risks. This is by no means "getting at" women drivers but, in my judgment, women often seem to take more risks than men.

Certainly, this is not a proper statistical survey. Perhaps I am used to bad male drivers! Maybe I just notice this as I am looking, but I can't begin to tell you how often I see bad driving and say to myself, "that was impulsive and poor" and it turns out to be a young woman at the wheel. Call me a male chauvinist pig if you like, although I am not. I am only saying what I notice.

Sunspots and 10m - Friday April 28th 2017

Solar flux is 78 today. Sunspot number is 23.  A= 7 and K=1.

60m band

According to Southgate News, Malta has just released its new frequency plan that includes the WRC15 5MHz amateur band. This is only 15kHz wide, so we must hope for more later.

10m and 6m WSPR again

Once again I am trying 10m WSPR (100% TX, 500mW) and 6m WSPR (20% TX 1W ERP, 80 % RX). Yesterday was hopeless, so I hope today is better! It cannot be any worse, HI. As we approach May there should be more Es.

UPDATE 1034z:  A 10m WSPR spot by DK6UG (633km), so there is some Es about on 10m today.

UPDATE 1835z: EA1FAQ (1249km) spotted me at lunchtime on 10m WSPR. No 6m WSPR spots all day.

Pye PF8 on 70cm FM

The Pye Telecom PF8 was, in its time, a very futuristic handheld UHF transceiver. They are very rare. I was fortunate to be part of the design team a very long time ago. I was responsible for the TX audio and the antenna which was quite novel. At the time Sir Clive Sinclair asked me for advice!

The PF8 was made famous in the UK TV series "The Professionals". If you can find one, they can be made to work on 70cms. Finding one is very hard. Before you ask, no, I do not have any. TX power was 500mW.

4m Allocations Worldwide

Certainly in Europe and in a few countries elsewhere, the 4m (70MHz) band is being allocated to the Amateur Service. Lower VHF is not so popular for PMR users as antennas are quite large. There is a real chance of more widespread amateur allocations at 4m. This is an interesting band which has decent tropo ranges and Es openings especially in the summer months.

M.E. petition - NOT amateur radio

See https://petition.parliament.uk/petitions/190618 .

The current treatment for M.E. is ineffective. This petition aims to get the UK government to "wake up" to this debilitating condition. If you agree, please consider signing it.

Heathkit Lunchboxes

These simple rigs for 10m, 6m or 2m were kits sold by Heathkit mainly in the 1960s. The limitation was the super-regen RX. I liked the styling and simplicity: no memories, AM only and just one crystalled channel on TX. It has long been my aim to make a modern version with similar styling.

Sunspots and 10m - Thursday April 27th 2017

Solar flux is 78 today and the sunspot number 36.  A=9 and K=3.

10m?  Maybe we'll see some Es? I doubt there will be any N-S F2 propagation.
