Rig1	I guess this is where they usually sit and conduct QSOs.
Rig2	This is an ideal amateur radio shack. I heard you have a hobby of radio-controlled airplanes, so I would like to see some videos of the models and flying of the radio-controlled airplanes (especially videos of the falling accidents).
ANT	CD-78jr (3.5M) and CD-730V (7M-28M), 3.5M has a power supply point commonly known as Robocon.
３DDS	This is a signal generator with three outputs, two of which have microhertz resolution and each output is I/Q. The output level is up to 3Vpp, and when used with an external reference clock input, it can be used for a wide range of purposes such as a standard signal generator or carrier wave output as a stable, high-precision signal.
GPS （TU60)	I had no idea it was made in this format. By the way, I can't find the TU60 unit inside, so where is it attached?
ロボコン	The head of the station also has a Robocon attached to the power feed point, which he apparently asked a local station to make. He seems to have measured and compared the SWR characteristics of the antenna he is using (CD-78jr) with a homemade Z-500 power meter and Diamond's SX1000, and I think the results are excellent for the Z-500. SWR characteristics of the CD-78jr. Even so, the Junior has a narrow bandwidth. I'm thinking of getting one for my CD-78L as well (I'll refrain from doing so as the Junior head of the station will be disappointed). But it's great that this can be used at close to 1.0 SWR on any frequency.
自作マイク	This is a microphone that was made in competition with other people using Primo's condenser element. It's made of green bamboo now, but I wonder what will happen as time goes by. Will it turn brown?
RL_Monitor	By using the opposite side characteristics of the SSB transmitter/receiver in conjunction with a spectrum analyzer, it is possible to directly view the opposite side characteristics at any frequency (HF band) in one shot and make adjustments while monitoring.
RX_Uranus	Colins' 455KHz mechanical filter (some people call it a ceramic mechanical filter) provides excellent fidelity and selectivity when receiving PSN, and the 455KHz filter can be shifted up to ±1KHz to eliminate interference.
TX_Saturn	This is the process of making a direct transmitter. The direct line of sight characteristics of the low pass filter (active) and the RF BPF characteristics are as follows. The overall characteristics of the BPF are excellent, with 3.5M as the standard, 14M = within -3dB, and 7M = about -4dB.
LCR Meter	A few stations have created LCR meters that can be purchased inexpensively from Amazon. They are placed in a case purchased at a 100 yen store, and the blue battery is a 2-cell lithium-ion battery that I had on hand, and the lever for inserting the parts is cut into the case.
MR-Neptune	Direct Receiver　of　HF-AllBand
Reference Comparator	This is a jig that rotates an LED, but has been modified to determine the LED rotation direction based on the phase flow direction. It is introduced in the individual menu 'Reference Clock Adjuster/Comparator'.
