█ KRAFT PT-7C 7 Channel system █ クラフト模型用プロポーショナルラジオラジコン７チャネル

This is a famous Kraft system, the "KRAFTSERIES SEVENTY-FIVE KPT-7C" 7-channel model released in 1975, a product of Kraft's golden era (1968 - 1980). This radio is one of about 10 sets purchased from the U.S. about 20 years ago and in relatively good condition. It is one of the maintenance equipment in our warehouse. At one time, most of the contest radio-controlled flyers in the U.S. used the Craft. I think it is safe to say that when it comes to radio control, it is the Craft. At that time, Craft had a production capacity of 400 units per week, a very large number considering the size of the market. Although expensive, they had a special reputation for reliability and build quality. It ...

This is a portable microwave spectrum analyzer manufactured by Tektronix, Inc. With the exception of some high-frequency oscillation circuits, all other components are semiconductors. Most of the functions...

I recently acquired this set and was surprised that it worked normally despite being manufactured approximately 70 years ago. The actual measured values were as follows Output: 25 dBm (about 300 mW) Modulation transition frequency: 25 KHz(FM) Receiving sensitivity: -110 dBm I was surprised at the sensitivity. The video shows 49.14 MHz at SG (signal source) transmitted from the antenna with 25 K...

My Blog minkara.carview.co.jp/userid/651150/blog/47561568/ We tested the operation of a digital radio system manufactured by Orbit, Inc. of the United States. The system was launched in 1966, nearly 60 years ago, and was adopted by many advanced modelers as a complete system at that time. It has been almost 30 years since we acquired the system, and we checked its operational status for the fir...

My BLOG:minkara.carview.co.jp/userid/651150/blog/47475085/ These model radio control systems were commercially available from "Citizen Ship" in the late 1960s. These were early proportional systems, consisting of a model DPT transmitter, a dedicated receiver, a servo set and rechargeable batteries. These radios are in the 27 MHz band (27.195 MHz), but other models are available in the 72 MHz ba...
