Done. Locally, KSCO\'s antennas are located in Corcoran Lagoon (Santa
Cruz, California):

The excellent salt/brackish water grounding is responsible for KSCO\'s
very strong signal and large coverage area.

Hi,
I
am looking for similar tool. Did you find a solution?

YA

Yaseen, there are DOS based programs for binary/Hex file splitting with
respect to EPROM programming. Can\'t recall the name but a bit of
searching should lead to the answer. This was talked to death back in
the late 90s and early 00s, so you should be able to track it down.

12 years is not a record for oldest Usenet post responded to!

Thanks John, Yes you are right, I can find DOS based programs.
Unfortunately I am limited to the option of using WINDOWS only.
I did find a programming by python tool (https://phyton.com/support/updates) window based but the splitted output file is not correct.

True, but with one notable exception. The original space suits were
ugly green pressure suit affairs, that looked awful in press photos
and videos. So, NASA hired fashion designers Rudi Gernreich and later
Pierre Cardin to design something futuristic and more in line with
science fiction. The result was the silver lamé space suits.

I just ordered a pulled 1M30D-060 from Dalbani which is based in FL. I\'ve checked around and they appear to be a reliable source that has been around for ages. They\'re not fake proof but, apparently, when a problem occur, they\'re quick to dispatch a replacement.

I can support the fact that Dalbani has been around for a long while and used to order tv, vcr, and microwave parts from them. Am surprised their website is parked. They out of business?

I have been using a 5 turn frame antenna *just* like that since the late 70s !!

My * tube AM tuner* has a transformer balanced input for use with a loop.
Like the Carver TX-11b, it also has 15kHz audio bandwidth and low THD at 95% mod plus a switchable, sharp notch at 9kHz.

But the maker ( here in Sydney) did not suggest using a frame antenna in the handbook, nor had one been tried when I asked.
His method was to run a fixed, single turn loop around a window.

The frame is better as you can orient it to maximise the signal or null an unwanted one.



**Audiosound?


** How\'d you guess?

**\'Cause his AM tuners were fabulous. I sold his SS AM tuners in my shop
(well, in truth, only a minuscule number, because they were very
expensive) and used to delight in demonstrating them to unsuspecting
customers who thought they were listening to an FM transmission. Very
impressive things. No wonder every radio station used one for off-air
monitoring.

Yes, the famous AM100 valve tuner.

BTW mine has a few mods now.

1. 4 pin mic plug and socket for the frame antenna.
2. Op-amp ( TL071) buffer for the output with voltage doubler +/- 8VDC supply off the 6.3v heater run.
3. Out level control on the rear panel with 6.3mm jack socket.
4. Hum loop eliminator in the AC safety ground.
5. New ceramic valve sockets.

It needs a new EM84 \"magic eye\" indicator - but they are darn expensive.

**I\'ll see what I can find in my valve box(es). You never know your luck.

The Carver tuner is interesting:

**Very interesting. I\'ve never had one across my bench. As a teenager, I
built a really nice valved, TRF tuner, using an \'infinite impedance\'
detector. It was from a Kiwi radio magazine from the 1950s. It was so
nice, I once called up the radio station (prolly 2SM back then) and
asked them to change the stylus on their \'B\' turntable, because it was
obvious that the stylus was worn/chipped. Geez it sounded nice.

I used to buy parts from Dalbani many years ago, and they were one of the suppliers that sent me counterfeit semis. I mostly bought basic stuff from them like VCR mechanical parts after than, but no more semis. They\'re still in Florida but I\'m sure they\'re not the same company they were.

** Probably correct.
The AM100 was sold at a tiny profit mainly direct to existing Audiosound customers.
Dealers were rarely involved.
Only competition back then was the \" Wright Audio Developments\" SS tuner.
As you know, I worked for Allen Wright too and while there modded a few tuners so the notch filter was at 9 kHz.
At that time he was building an upgraded model, full of ICs and featuring an LED digital frequency readout.
Till Ian Pogson of EA magazine stole the whole design.

FYI:

Took one of Allen\'s new models ( the AWE Tuner) home one night and did A-Bs with my Audiosound.
Though generally similar, the AM100 had a big edge in audio bandwidth on the ABC stations.
Like his earlier tuner, the new one also had no bypass switch for the notch filter.

For about $300.00 one could buy a quite decent, all
digital, Japanese AM/FM tuner. Of course, the AM section was utter shit.

** Dull and woolly sounding - you mean ?

I suspect the reason why Aussie AM tuners reached a pinnacle of quality
