[Receiver] Reception method Single superheterodyne Sensitivity 0.2?V input S / N 10db or more Oscillation method Variable crystal oscillation (VXO) I was able to accidentally get a radio from the West Radio Research Institute, which I had heard about before. It looks like Mizuhos Picotra, but when you look at it seriously, it was a rugged radio with a maniac smell. VXO is adopted as the frequency variable method, but only 100KHz from 144.150 to 144.250 is used, and the frequency change by crystal replacement like Mizuhos picotra is not considered. Although the frequency variable width is 100KHz, it is divided into two, A-BAND and B-BAND, and AB is switched by a toggle switch near the BNC connector. 1VXO and 50KHz are exactly the same as Picotra. Although the S meter also has a terminal, the user takes a method of preparing a separate radiator. Instead, the LED near the BNC connector is used in an interesting way. The brightness increases and decreases according to the signal intensity during reception, and the LED increases and decreases according to the volume of the voice (= output) during transmission. Its a glowing mechanism. I think that this is useful in actual operation because it functions as an S / RF meter with no meter. Although equipped with RIT, it is not center locked like Picotras VR, but uses the same type of VR as the power supply and volume, so it turns to the far left and click sounds with RIT-OFF Become. The frequency is adjusted with TUNE, but it does not use a variable capacitor like Picotra and is VR (variable resistance). Looking at the top panel print, if you think that it covers 50KHz in the full range of VR, only about 80% of the total is used. (Because the printing itself is only 40KHz, about 70% if only characters) Sending from the NTS-200 connected to the dummy load and confirming the transmission frequency with another Rig, 144.140-205 with A-BAND, B-BAND Then it covers up to around 144.195-144.260. Is it a feeling of variable width of about 65KHz? The PTT switch is also large and has a click and a strong click feeling, so switching between sending and receiving is comfortable. On the other hand, the knobs on the top panel feel tight and frustration is great when performing operations other than PTT. Also, because the speakers also use very small products, the sound is not as good as the Picotra S series, which is the subject of comparison, and the sound is tiring. I think its a space issue, but its a shame. As for the power source, there is only space for six AA batteries, so if you use a rechargeable battery such as nickel metal hydride, it will be 7.2V far from the specified voltage of 9V. Personally, I like to go out after being fully charged with nickel metal hydride or nickel-cadmium batteries, so I think its a shame that the built-in battery is only dry. NTS-200 was released in 1992 as a 144MHz band / 1W SSB / CW (OPTION) transceiver. Yes. I dont know in detail, but it seems that there is a link between the West Radio Research Institute and Mizuho Communications, so it doesnt seem to be irrelevant. (The MX-2F is not available, so it cannot be compared and details are unknown) As of 2005, NTS210 (144MHz) and NTS710 (430MHz / discontinued), which have become PLL systems, have been published on the official site at West Radio Research Laboratory. The price is close to a maniac number, but I hope that it will last for a long time because it is one of the few small-scale manufacturers in Japan. Payment We only accept PayPal payments.
