Time expansion bat detectors


Time expansion bat detectors

Time expansion (TE) detectors are broadband detectors, i.e. they detect all frequencies across the frequency range within which bats are likely to be calling.

They work by digitally recording a brief snatch of bat sound (usually about one second) and replaying it at a slower rate, usually ten times slower. Thus a frequency of 50 kHz is lowered to 5 kHz which is within our hearing range. The advantages are that the entire structure of the call can be heard enabling species identification using sound analysis software and the sonograms tend to be of a very high quality. The disadvantage of the time expansion system is that while the detector is playing back the slowed-down sounds it becomes "deaf" to any bats flying past. However, many models also include heterodyne or frequency division systems which can be heard on one side of your headphones, enabling you to keep on listening to "live" bat sounds and to decide when to capture another snatch of bat sound in time expansion mode. Time expansion detectors tend to be more expensive than heterodyne and frequency division detectors.

Listen here for examples of calls heard on a Time Expansion detector:

Soprano pipistrelle echolocation calls

Nathusius' pipistrelle echolocation and social calls

Noctule echolocation calls

If you are a beginner then this kit is a perfect introduction to the detection of bats!

The kit includes:

  • Magenta Bat5 superheterodyne bat detector
  • Four AAA batteries
  • A Field Studies Council 'Guide to British Bats'

 

The compact Magenta Bat5 has a backlit 4 digit LCD frequency display which is highly visible during the day and night and a top-illuminated large-diameter frequency dial. Bat detectors work by converting the inaudible ultrasonic calls into sounds that we are able to hear (100 to 12kHz). It has an extended low-frequency coverage so it will be able to detect insects and some birds, in addition to bats.

Key features:

  • An enhanced oscillator frequency range and low noise
  • Easy one-handed operation of volume and frequency controls
  • Low power consumption
  • Contoured microphone housing for enhanced frequency sensitivity
  • Waterproof, short circuit proof headphone output
  • Low-level output for connection to a recorder or PC sound card
  • Built-in LED torch
  • Wrist strap

 

The FSC guide contains a detailed description of the different calls, flight patterns, and behaviours of the UK's bat species and is an ideal companion for anyone learning to identify British bats.

Save the pavilion at Tudor Park

Renovation is long overdue, says the Friends of Tudor Park Pavilion group

Hero for Save the pavilion at Tudor Park
Inside the pavilion at Tudor Park
By Simon Cohen 05 January 2022

The repair and renovation of the neo-Georgian-style cricket pavilion in Tudor Park built by S Maw & Sons in 1920, is long overdue. 

Early in 2020, it was included in Barnet Council’s local heritage list as being of historical and architectural interest because of social and community value, its age and rarity, and landmark qualities. 

The residents’ survey which I organised last spring had 1025 responses and showed that local people very much wanted a café in a refurbished pavilion with public toilets and new community space. 

There have been numerous attempts over the past decade to get the council engaged with repairs and to find a way to re-use the building. At the LBB Chipping Barnet Area Committee in June 2021, a motion was passed to fund £200,000 for structural and refurbishment work. 



I have since set up a Friends of Tudor Park Pavilion group which has produced its initial Vision Statement. A suggested layout change of the pavilion interior could enable a more flexible central space for community activities, classes such as yoga, pilates and art, playgroups, exhibitions, and meeting rooms for local clubs and organisations.

A café would be a perfect focal point: close to the existing children’s playground, it would provide a place to meet with friends or get out of the home office to do some work. Other improvements could include a completely new kitchen to cater for events and functions. 

It would be great to get more feedback and involvement from the community so we start 2022 with a strong voice and clear direction for the council to move the project forward. We hope the regeneration of the pavilion will be part of the Masterplan for improving amenities and the quality of the Tudor Park open space. 

Please show your support by emailing FriendsOfTudorPark Pavilion@gmail.com and share your ideas with us.



Barnet Council is under renewed pressure to carry out a full survey of repairs required to restore the dis-used Tudor Park cricket pavilion in New Barnet.

A local campaign led by Barnet Society committee member Simon Cohen believes up-to-date estimates for the work need to be obtained so that councillors and residents can explore the options for returning the pavilion to public use.

Mr Cohen organised a survey of local opinion to test support and he says it shows overwhelming backing for the pavilion to be re-opened.

Of the 1,016 responses to his survey, 984 wanted it restored and the most popular requests were for a café (85 per cent in favour), public toilets (41 per cent) and community space (39 per cent).

“I was stunned by the level of interest,” said Mr Cohen.

“It was so encouraging to get near total backing for our campaign to prevent this historic building falling into further disrepair and then being abandoned by the council.”

Tudor Park’s cricket pavilion, opened in 1920, has been boarded up for the last ten years and the council has estimated in the past that it would cost around £180,000 to repair and make safe.

Mr Cohen says High Barnet councillor David Longstaff has promised to take up their demand for fresh estimates for refurbishing the pavilion which is deemed unsafe because of subsidence and collapsed drains.

“What seems to have happened is that one of the council’s preferred contractors came up with the estimate for £180,000.

“What is needed is a proper survey and for estimates to be broken down so that we can see how much essential repairs would cost and what new facilities might be possible.

“Local residents were so angry when we discovered that the council had downgraded Tudor Park to the status of a “low quality, low value park” and the least the council can do is allow the community to have the full facts and conduct a full and open debate.”

Tudor Park and sports ground is a well-used venue offering playgrounds for both toddlers and children and the Tudor Park Footgolf course which has been laid out on the former East Barnet Golf Club course.

“There is no doubt a café in the pavilion would be extremely popular. There was a previous attempt to open a café there, but it failed because of the cost of repairs.

“A community space within the building could offer all sorts of possibilities. Next door are New Barnet allotments, and the plot holders could be encouraged to use the space to sell surplus produce.”

Mr Cohen decided to launch his campaign – SaveTudorParkPavilion – after realising last year that it was the centenary of its opening in 1920.

“I have known the pavilion for 50 years, and my children have grown up as regular visitors to the park and playground and it would be catastrophic for the community if we couldn’t find a way to put such an historic building to good use.”

Originally the pavilion, built in neo-Georgian style, served the sports ground opened by the former New Barnet medical supplies manufacturer. S Maw & Sons and it bears the logo of S Maw along with the date 1920.

Early in 2020 it was included in Barnet Council’s local heritage list as being of historical and architectural interest because of social and community value, age and rarity, and landmark qualities.

Tudor Park is a community asset that needs to be treasured and its pavilion brought back into use.

Tudor Park is popular and regularly used for fitness training, playing about in the playground, walks and exercise, sitting about, picnics, as well as by the footie golf players, and allotment holders on their way to and from their allotment....

This is a lovely period building and should be repaired and be a facility for locals A non profit cafe/restaurant would be very successful and it could be a venue for e.g. quiz evenings. Years ago there was a committee called Friends of Tudor and they organised terrific events in the Park for us locals. Vitally public toilets are needed....

A café would be a good idea. My children, grandchildren and great grand children have all played there. All 16 of the family.

This should be a community space with a not for profit cafe attached. The building could provide a nice place for families to hang out with safe and fun activities for the local community. Living Under One Sun in Tottenham Hale would be a really good model to base it on.

New Barnet doesn’t need a private cafe; Potters Pantry is 5 minutes round the...

I hope the same can be considered for the cricket pavilion at Underhill, which could be somewhere to display memories of Barnet FC as well.

Nice amenity to open up

 

Lifeline for Tudor Park

Barnet Council have allocated £200,000 to renovate and refurbish the sports pavilion in Tudor Park in the Hadley area of High Barnet. Local MP, Theresa Villiers, has warmly welcomed the new funding which was secured by High Barnet Conservative ward councillor, David Longstaff, a meeting of the council’s Chipping Barnet Area Committee.

Commenting on the news, Theresa Villiers said “For many years I have been urging Barnet Council to bring the pavilion in Tudor Park back into use. It has been sad to see this building stand unused for so long, getting steadily more dilapidated.”

“I very much welcome funding to finally get the pavilion re-opened and renovated. It was frustrating to highlight this so often with council officers but without success. This investment secured by Cllr Longstaff should transform the building and turn it into a great asset for the community. I am sure it will make Tudor Park – a hidden gem green space in my constituency – even more popular than it already is.”

“Thank you to Barnet Council to listening to the many residents who signed the Barnet Society’s petition asking for action to rescue the pavilion.”

The building in Tudor Park was originally a cricket pavilion but when it is re-opened it is expected to have a wider purpose, including facilities for the general public, such as cafe.

S. Maw, Son & Sons Ltd.

In 1814 George Maw, a former Lincolnshire farmer, purchased a surgical plaster factory at Whitecross Street in London. The factory soon began to manufacture surgical instruments and later expanded to produce a variety of medical and pharmaceutical products.

George Maw's son, John, was made partner in the business in 1826 and the company took the name George Maw and Son. George retired in 1828 and his second son, Solomon, joined his brother in partnership.

Ill health forced John to retire in 1835, but under the stewardship of Solomon the business flourished and expanded rapidly.

The company moved to larger premises at Aldersgate Street, although the factory had to be completely rebuilt following a fire in 1856. In 1860 Solomon Maw's son, Charles, was taken into partnership and the firm was renamed S. Maw & Son. In 1901 the firm was incorporated as a limited liability company with the name S. Maw, Son & Sons Ltd.


Due to lack of space for further expansion, the company purchased a 22 acre estate in Barnet in 1920, and moved a large part of its manufacturing operations there. In 1973 S. Maw, Son & Sons Ltd. was acquired by the American company, International Telephone & Telegraph Corporation Inc. despite this company having no links at all with the pharmaceutical industry.

Maw used a variety of perfin patterns during the 20th Century, but I am not aware of any use on stamps from the Victorian Era.
