Using the Radio Shack at OH73ELK

1. Preparation

Please check the antenna connector. If it is unplugged, please connect it to the transceiver jack of the IC 7300.

Then you need power, so insert the black plug into the socket under the table (see picture):

Then, turn ON the general  switch on the table:

Please switch OFF the general switch every time you have finished operating.

2. Operation

Transceiver

If you are not familiar with the Icom 7300 transceiver, please read the manual which is on the table. Turn on the transceiver. The power of the transceiver can be set here:

The IC 7300 is a touch screen / menu-driven transceiver. If you are not familiar with this technology, please read the manual.
Here is one important example: Do not look for a band switch. In order to switch bands, push the touch screen here:

Antennas

VERY IMPORTANT: always set the antenna to the appropriate band with the switch RQUAD “RU-005A”:

Every time you change bands, you need to check and/or switch the antenna!

The following antennas are available:

• Red button 1: Fullsize Yagi beam for 20-15-10m
• Red button 2: GP 40m (works also on 20 m)
• Red button 3: Inv-V for 80 m (works also on 17 m)
• Red button 4: not in use
• Red button 5: not in use

As mentioned before, every time you stop working, please turn off the general switch. This also switches the antennas to ground! This is very important for protection against static electricity and thunderstorm hazards. If you stay during summer when thunderstorms are possible, please carefully disconnect the antenna from the transceiver upon departure or during thunderstorms.

Yaesu rotor G-1000DX

The rotor is centered NORTH and allows to turn the 10/15/20 beam through 360 degrees. The rotor has a certain "overlap" capacity going beyond 360 degrees.

Please use extreme care when using this rotor and DO NOT OVERLAP across NORTH.

(For example: when turning the antenna from NORTH to SOUTH or EAST, rotate COUNTER-CLOCKWISE ("left"). When going back towards NORTH, rotate CLOCKWISE - "right").

During the winter season, at temperatures below -5 degrees, please use the rotor as little as possible.

If the temperature drops below –10 ° C DO NOT USE THE ROTOR (such temperatures are outside the working range of this Yaesu rotor).

In this situation, you can use the GP 40m/20m (Red button 2)

This GP is also working on 20 m band!

Headset / footswitch

The station works very well with the current setup. Please do not change the wiring or add peripherals without the consent of Alex.
In case you need to use the headset Heil BM-10 iC and footswitch Heil FS-3, please inform Alex before your arrival.

Leaving the station

At the end of your stay, please carefully disconnect the antenna from the transceiver, turn OFF the general switch and disconnect all plugs from the sockets.
Obviously, you should also disconnect the antenna during your stay whenever thunderstorms are approaching.

Amplifier

The shack is equipped with an amplifier (under the shack table) and a remote control unit (on the shack table).

Do not use this equipment without prior authorisation by Alex. Without proper introduction and briefing, the use of the amplifier equipment is dangerous and can lead to extensive damage.

Also, even if they look interesting, never touch any controls on the amplifier.

3 General remarks

Please always use sound judgment concerning safety issues. In case of doubt, think twice.

Do not even think about climbing the tower or similar activities.

If you want to erect your own antennas, please check beforehand with Alex.

Enjoy your stay at OH73ELK!
