To find out the true frequency I need another transmitter or reference VFO that can transmit in this range. The way the morse receiver works the frequency displayed is not the actual frequency it's listening to, though the difference isn't large.
Homebrew 50 MHz Frequency Counter built in 1972. At the time, a 50Mhz was pretty advanced. My own design, but functionally it was similar to an HP 10MHz counter that used nixie displays. I think there are about 50 DIP chips, mostly 7400 TTL, on 8 PC boards. The largest board is about 4" x 12" with 21 DIPs (3 per decade), hidden in the base of the chassis. Today, this could be built with a few inexpensive chips, with much better performance. But, it still works, and I built it, so I use it... ;-)
Founded in 1995, Harmonix Music Systems originally intended to create interactive music composition systems. After a series of failures and dead-ends, they researched the burgeoning rhythm game genre in Japan. The resulting game was Frequency.

Lìjiāng (simplified Chinese: 丽江; traditional Chinese: 麗江) is a prefecture-level city in the northwest of Yunnan province, People's Republic of China. It has an area of 21,219 square kilometres and had a population of 1,244,769 at the 2010 census.
HISTORY
Lijiang City replaced the former administrative region of Lijiang Prefecture. It was under the rule of the Mu family (木氏) local commanders (土司) during the Ming Dynasty and Qing Dynasty.
The Baisha Old Town was the political, commercial and cultural center for the local Naxi people and other ethnic groups for 400 years from the year 658 AD to 1107 AD. The Dabaoji Palace of the Baisha Fresco, very close to the Baisha Naxi Hand-made Embroidery Institute, was built in the year 658 AD in the Tang Dynasty (618 AD to 960 AD).
In ancient times, the Baisha Old Town used to be the center of silk embroidery in the southwest of China and the most important place of the Ancient Southern Silk Road, also called the Ancient Tea and Horse Road or Ancient tea route. The Ancient Southern Silk Road started from Burma, crossed Lijiang, Shangri-La County, Tibet, journeyed through Iran, the Fertile Crescent, and ultimately to the Mediterranean Sea.
Naxi women were well known for their hand-made embroidery before 1972 during the Great Cultural Revolution. The most famous Naxi masters were arrested and put in jail, some of them died in jail during the Cultural Revolution because they did hand-made embroidery only for the Naxi Emperors when they were young.
GEOGRAPHY
Lijiang is located in the northwestern portion of Yunnan and borders Sichuan. It is in a region where the Qinghai-Tibet Plateau and Yunnan-Guizhou Plateau converge.
Owing to its low latitude and high elevation, the city centre of Lijiang experiences a mild subtropical highland climate (Köppen Cwb). Winters are mild and very dry and sunny (>70% possible sunshine), although average lows in December and January are just below the freezing mark; January, the coolest month, has a 24-hour average temperature of 6.0 °C. Spring begins early and remains dry and sunny until late May, when there is a dramatic uptick in frequency and amount of rainfall that lasts until late September. Summers are warm, rainy (more so than it is sunny) and damp, with June, the warmest month, averaging 18.4 °C. Autumn sees an abrupt reduction in rainfall and return to sunniness. The annual mean temperature is 12.70 °C, while precipitation averages 968 mm, around 80% of which occurs from June to September. With monthly percent possible sunshine ranging from 32% in July to 80% in December, the city receives 2,463 hours of bright sunshine annually.
OLD TOWN
The world famous Old Town of Lijiang is located in Lijiang City. It is a UNESCO Heritage Site.
The town has a history going back more than 800 years and was once a confluence for trade along the old tea horse road. The Lijiang old town is famous for its orderly system of waterways and bridges. The old town of Lijiang differs from other ancient Chinese cities in architecture, history and the culture of its traditional residents the Nakhi people, therefore people there are called 胖金哥 and 胖金妹 (pàng jīn gē, pàng jīn mèi, male and female respectively). The town was ruled by the Mu Family during the portions of the Ming and Qing Dynasties, a period of nearly 500 years.
Overlooking Lijiang Old Town is Lion Hill and at its summit is the Wangu Pavilion, which is a wooden building that stands 33 m tall and boasts 10,000 dragon carvings. The pavilion is constructed on 16 columns each of 22 m in height. The pavilion is a masterpiece of Qing Dynasty architecture that has been extensively restored following the designation of Lijiang Old Town as a UNESCO Heritage Site.
From Lion's Hill it is possible to view the entire Li River valley, including both the old city and new city of Lijiang. Looking Northwest, the Jade Dragon Snow Mountain is dominates the horizon.
The Old Town is a maze of winding cobblestone streets. It is extremely easy to get lost as there is no grid, but each turn takes one to some new interesting spot, and it's not hard to eventually find one's way out of the maze and back to familiar territory. The layout of the town was established to conform to the flow of 3 streams in adherence to Feng Shui design, so there was water and waste disposal for the inhabitants. The Old Town has fast become a destination for young Chinese artists, students, and adventurers. Most recently, it has become a favored Spring Break destination for students. "Bar Street" is a line of clubs with live music, dancing, and revelry. The Old Town has a multitude of shops, some a bit tourist oriented, but several showcasing handcrafts, individual artists, and local manufacturers of interesting personal products.
There are dozens of restaurants, from snacks to high end dining, all very reasonably priced, cheap by Western standards.
Accommodations are varied, but the most interesting are the large number of boutique hotels run by individuals and families. These boutique hotels are in old traditional houses converted to rooms, courtyards, and gathering places, and designs all trend to traditional Chinese sensibilities. There are new high end hotel and condominium developments starting construction from 2011 forward, so there is a definite push to make the destination one for all tastes and not just young adventurers.
NEARBY
Some tens of miles north of Lijiang is the Baishui Terrace (白水台 Baishuitai, literally "White Water Terrace"), an area where spring water flows over a sinter terrace, leaving behind travertine. Lijiang is also close to the Jade Dragon Snow Mountain (玉龙雪山).
A few miles north of Lijiang is the village of Baisha, famous for the Baisha Fresco and the Naxi Hand-made Embroidery Institute.The Fresco was built in the Ming Dynasty 600 years ago, the Naxi Hand-made Embroidery Institute was built 800 years ago, it is the headquarters of the Naxi embroideries and also, a school for the Naxi embroiderers. There are many Naxi embroidery masters, teachers, students and local farmers there. Their embroidery arts can be found there.

Europe's grid frequency was lower than the spec in Feb /
March 2018. That made 50Hz-synchronous clocks lose
some minutes. It has caught up in the mean time.

Canada's first double-deck hop-on hop-off wine tour is based on Wolfville, Nova Scotia. The tour links several wineries on an hourly frequency between May and October on Thursdays, Fridays, Saturdays and Sundays.
The tours are organised by the wineries that are visited using former London RML 2673 (SMK 673F) operated by Absolute Charters, Halifax. The bus carries a suitable advertising wrap featuring amongst other things a wine bottle!

1, 2, 3, 4, sequence of prismatic polyhedron antennas
These antennas were invented by N2DT and G6GPR after simulation studies by N2DT, and designed to have 50 ohm driving point impedance over progressively wider bandwidths. N2DT intended them to be HF antennas for Ham Radio use, but G6GPR made them into microwave antennas for measurements in the laboratory. The fat conductors make the design dimensions far less critical, so these are "well behaved" antennas. The whole process is a combination of modern mathematical simulation tools together with insight derived from semiconductor physics, where many coupled identical elements create a band of frequencies from a single resonance.
Radio frequency treatments can help you solve a number of problems that you may be up against as a result of aging like sagging skin and pain in joints.
