Ioannis Lempidakis was born in Heraklion, Crete on 07-10-1942. His love for electronics started at a very young age (around 8 years old) when he first came in contact with various electronic components such as batteries, light bulbs, etc. His stubbornness and obsession with electronics led him at the age of 16 to repair radios of that period and be one of the most recognized TV/Radio electronic engineers of that time.

After the end of his term as an engineer and RADAR trainer in the Hellenic Air Force, Ioannis Lempidakis started manufacturing his first instruments-devices such as Medium and short-wave radio receiver, Cathode ray tube oscilloscope, Intermediate audio frequency level at 4.5MHz and an acoustic frequency amplifier which was used in 1971 for the reception of the American television station in Heraklion, Crete, in order to make the European televisions compatible with the American audio standards and in order for someone to be able to watch this specific station with image and sound.

One of the first devices of LEBAND Electronics was a portable Video generator in a leather case, the PG101. They were quite successful commercially and for this reason they were evolved, thus presenting two new models, the PG102 and PG103. During the same period, LEBAND Electronics manufactured various other products such as TV audio converters, TV generators desktop instruments, laboratory power supplies, etc. with different variants and technical characteristics. A professional oscilloscope, the OS-201, was designed around the same period of time, which never went into production as its cost was quite high and the materials (screen and magnetic shielding) were hard to find. In addition to the professional products, a few retail products were also manufactured, such as the STEREO-5050 which was a stereo sound amplifier for home use. A total of 20 pieces were sold. Moreover, during the same period of time, other types of domestic appliances were designed, such as the black and white televisions with printed circuit boards, which were very successful and brought a lot of profits to LEBAND Electronics.

In 1982 LEBAND Electronics wanted to manufacture color TV generators instruments, which were quite demanding in their design and construction and that was a very big challenge. As the first TV color generator brought significant profits to the company, the second version PG301B was built soon after, which launched sales in Greece and abroad to the sky.

In 1988 LEBAND Electronics tried to enter the field of desktop power supplies by manufacturing two such models, the PS201 and the PS202. Unfortunately, the first pilot batch built and marketed had a design flaw which created a very serious problem in the operation of the power supplies. Although the series was immediately redesigned to solve the problem, the damage was done, creating a strong negative reputation in the market which did not allow further sales. The same fate befell the largest power supplies on the market PS501, PS502 and PS503 that never went into production and remained only as prototypes.

In 1991 LEBAND Electronics manufactured the first professional analog TV headend which consisted of Power Supply (PSP1), Terrestrial receiver (TVR2), Terrestrial TV Channel Converter (TRM1) and Dual satellite analog receiver (SAT1). This headend was state-of-the-art for its time as it used CPU-controlled PLL technology, competing strongly with any similar product of the worldwide market. This series was a great success, launching sales and establishing the name LEBAND in the field of professional installations.

In 1993 LEBAND Electronics, using the units from the first professional headend, built the first 1W (PEAK SYNC) analog TV transmitter, which consisted of a modulator in the IF TV band with professional (vestigial) features(IFM1), an up converter from IF to UHF (UCU1), a power supply (PSP1), and a UHF transmitter (PA1W-75). This transmitter was a great success as, at that time, while many new private stations as well as many municipalities had to cover their areas, opening a new large chapter for LEBAND Electronics in the field of the analogue TV broadcasting.

LEBAND Electronics was particularly successful and became famous for the analog RF PAL modulators it started manufacturing in 1995. The first model to be built was the MOD1 which operated on the CH02-CH04 frequencies in VHF. The first version of the product did not have a PLL to lock the output frequency. About a year later, in 1995, LEBAND Electronics redesigned the MOD1 to feature PLL and at the same time designed a complete line of PLL modulators that covered all available frequencies.

With the analog monophonic modulators being a great market success, LEBAND Electronics expanded its product range with five stereo modulators.

Between 2001 and 2005 LEBAND Electronics enjoyed the success of its products developed in previous years but at the same time did not stop developing new products, offering new solutions to the market at affordable prices. At the same time, other products were manufactured such as 1W UHF power amplifier, analog TV receiver/demodulator, RF filter-mixers, analog TV broadcast output filters, professional Vestigial headend for analog TV modulators, wideband & narrowband amplifiers.

Lemco continued the successful course of LEBAND Electronics by creating new analog TV products, such as the Compact 10 headend, ideal for small business installations. At the same time, 2007 is a milestone year for Lemco, as digital television has already made its appearance in Europe and the rest of the world, and Lemco is launching its first research and development efforts to create its own digital TV products. Meanwhile, Lemco keeps participating in various exhibitions.

After about 4 years of intensive research and development, Lemco Electronics begins to produce the first digital TV products. These products are digital DVB-T transmitters and low power transposers (up to 6W RMS) with MPEG2 image compression technology. Although, due to the change in the installation process of transmitters / transposers in the country, the transition from MPEG2 to H.264 as well as the high cost of their production, this series was not very successful, with just a few pieces being sold in the local market. At the same time, individual digital TV broadcast amplifiers were built.

Lemco's participation in ANGACOM 2013 did not lead to the expected sales, but the unavoidable cocnlusion was the need to redesign almost all of its products as, in several cases, the prices offered were almost double of those of competing products in Europe. In 2014, Lemco participated for the second time in ANGACOM 2014, with new products, more competitive but also with an upgraded stand.

The years that followed resulted in Lemco’s constant growing and evolving, creating new products that were highly competitive in both performance and price. At the same time, Lemco participates in many exhibitions in the field, both locally and abroad. ANGACOM 2015 in Cologne-Germany, CABSAT 2019 in Dubai-UAE and CommunicAsia 2019 in Singapore.
