Tescun Pl 660 vs. Sony ICF SW7600GR

Decisions, decisions.

The Sony has NO TUNING KNOB, IS MORE EXPENSIVE, but is a better radio.

The Tescun 660 costs a lot less, has a signal processor as good as the Sony, has tuning knob, an air band, but like Baofengs, has a rep of units inexplicably dying after a year or two, being in need of recalibration, and other quality issues.

People who have a good one swear by them.

The Tescun 880 is newer, has a line out and better controls, but a shitty signal processor, which really sucks if you like SSB as I do.

The Sangean 909x is reputedly deaf on SW without external antenna.

Opinons are welcome.

Royal Observatory @ Greenwich working first time since London smog shut down telescopes 60 years ago

The Royal Observatory at Greenwich has been pivotal to astronomy and navigation since the beginning of time. Well, international standard time at least. But what few people realise is that the observatory has not actually observed anything for more than half a century.

Astronomers were forced to abandon their work in the 1950s as London smogs grew so bad that they could no longer see the stars through their telescopes.

As the railways expanded nearby, the rumble of trains also made it impossible to take accurate readings with sensitive instruments, while the ever-growing capital brought increasingly dazzling light pollution.

Now, after more than 60 years a new telescope has been installed at Greenwich to restore its status as a working observatory once again. Not only is London’s air cleaner now, but modern telescope filters can tune out the pollution to hone in on the stars, planets, nebulae and even galaxies.

Curator of Royal Observatory Greenwich, Dr Louise Devoy said: “The observatory really started to wind down in 1948 because Greenwich had been expanding, and Greenwich Power Station was belching out smoke so the telescopes were becoming useless.

“They also used to do magnetic and meteorological readings from here, but the railways and iron-framed buildings interfered with the signals and the vibrations from the trains made accuracy impossible. With the new telescope we can use filters and software to process it all out.”

"Transmitting Greenwich time Edit
The master clock, at first called the Normal Clock or Master Clock, but later known as the Mean Solar Standard Clock, sent pulses every second to sympathetic or slave clocks in the Chronometer Room, the Dwelling House (Flamsteed House), and at the gate (the Gate Clock). A pulse was sent to the time ball at 13:00. The signals were also transmitted along cables from Greenwich to London Bridge. From London Bridge a time signal was distributed at less frequent intervals by telegraph wires to clocks and receivers in London, Edinburgh, Glasgow, Dublin, Belfast and many other cities. From 1866 time signals were also sent to US Harvard University via the new transatlantic submarine cable.

Airy's report to the Observatory's Board of Visitors in 1853 explained the function of the Shepherd master clock:

This clock keeps in motion a sympathetic galvanic clock in the Chronometer room, which, therefore, is sensibly correct; and thus the chronometers are compared with a clock which requires no numerical correction.

The same Normal Clock maintains in sympathetic movement the large clock at the entrance-gate, two other clocks in the Observatory, and a clock at the London Bridge Terminus of the South-Eastern Railway.

It sends galvanic signals every day along all the principal railways diverging from London. It drops the Greenwich Ball and the Ball on the Offices of the Eastern Telegraph Company in the Strand.

All these various effects are produced without sensible error of time; and I cannot but feel a satisfaction in thinking that the Royal Observatory is thus quietly contributing to the punctuality of business through a large portion of this busy country."

Listening to "The Lumpy Gravy Show" - WBCQ Area 51

On an app.

Not sure if it's live or not.

Just played a 20 minute long tune.

Zenith "The Continental"

Just arrived from Ebay.

A.M., F.M., VHF 1 and 2, and UHF.

Gets the NOAA weather, covers most of the 2 meter band, haven't tried listening to the repeaters yet.

Reception on A.M. is very good for this type of radio, F.M. reception is excellent.

There isn't much on the other bands since T.V. went digital, but I did recieve an aircraft transmission.

Build quality is nothing like the solid state Transoceanics, this has a very light feel to it.

Then again, I paid about 20 bucks for it, not the hundreds that Trannies (radios) command.

It is a handsome radio and looks good on the shelf.

Minor glitches - The dial light stays on all the time, it is supposed to be switchable. I solved this by using a tiny paper shim on the switch, it works. Will look inside later.

The rotary band selector knob is very smooth and quiet without scratchiness, except on the bottom (aircraft) band. Applied contact cleaner. Seems to be common problem with these radios, the Realistic Astronaut 6 selector is absolutely awful, but it may have been damaged. (dropped.)

One of the battery compartment lidclips is missing, but one holds it on well. Battery compartment has no corrosion at all, perfectly clean.

The set has a smooth, rich sound.

It also has a working squelch knob.
Why you would want this on a manually tuned radio is beyond me, but it works.

Was listening to KDKA in Pittsburgh during daytime, about 250 miles from Erie.

Dual antennas, one for FM and one for VHF.

Made in Japan.
