Topic Welcome

Hoerwache is a virtual monument for nearly 100 years of Maritime Radio. From the early 1900's on, when wireless communication was invented for use by marines to exange message over sea on a world wide basis. Operators where trained to use Morse code keying on many a wireless frequencies. Hoerwache does simulate it perfect. After some practice one will understand the mechanism of it and find out it is very simple, logical and easy to handle. No registration or installation of software is necessary, your pc browser must only be HTML5 ready ! Just use a modern pc with sound card and browser like chrome, edge, firefox. Internet Explorer IE will not fit to the program!

Check your browser for HTML5 ⇒ conformity

It is a good practice to clean the browser cache! If something does not work in HW leave the program and delete the cache and restart HW. Browsers first look to its cache instead of loading pages from the domain. This behaviour saves transfer time via Internet!

Thanks to radio officer Dieter Lüpker of Hamburg - continous development was necessary to bring Hoerwache up to simulate maritime radio service so perfect!

Topic Start Hoerwache

Start your favourite browser - preferred chrome - edge - firefox , IE does not work !
You may check your browser version if it is HTML5 ⇒ http://HTML5test.com

Call hoerwache at ⇒ https://www.hoerwache.de

startscreen 1 Confirm to use https - 2 Drop down menue - 3 select Ship Station - 4 Language - 5 documentation, scroll down

Select one from drop down menue - Use 'Work as Ship station' for first steps in Hoerwache

Topic Ship Data

Enter your ship data - self explanatory - any name will fit

Call sign must be unique during a session, if used by some one else, use other call. Call is important, but any Call fit - ABCD is ok - its used for HW System to run it!

Your name for real or what ever you like - Micky Mouse will fit!

Select a route you want to follow. Some routes have connecting point

Shown is a route from Immingham UK to Cuxhaven

Button NEXT skips to the verification of your entries and -update- or -to go- to the Wireless Room at end.

Topic Wireless Shack

On entry HW displays this layout - All equipment is switched off, usage is explained further down 


         1 Radio Clock  2 Manifest   3 Receiver   4 Transmitter
         5 Band Select  6 Dial panel 7 Button Box 8 Audio Keying  9 Compass
        10 Seachart    11 Zoom +/-  12 Chart pan 13 Marker for ship/coast; DLBH active

On entry rx is silet because nothing is switched ON! When you check the receiver ON - button it turns rx on, button will be lighted, some noise will be audible. By default rx is turned to 500 kHz.

Topic Usage

Use the mouse to move around the controls and click on buttons and knobs to select an item. Mouse scroll is used as well for altertering values up/down. Sometimes click and hold to move sliders.

top

Topic Receiver

HW uses 2 receivers. Main rx 1 is an all band marine device, and rx 2 is fixed 500 kHz. By default this rx is set to mf-band. 500 kHz has a separate button for quick recall. Click on 1 to switch rx on/off, adjust volume at 2, point on button 3 and use scroll up/down frequency.
If no sound is audible perhaps your pc speaker is muted or basic volume of soundcard is to low - Now one can hear sferics and cw traffic from other stations.

You may store up to 7 frequencies for easy recall by pressing "str-key" and point to one of the buttons 1 .. 7 with mouse.

   
Band select

At 1 select desired Band : mf or hf bands according ITU allocated frequencies. Dial screen will show and rx panel is updated as well.

   
Select frequency from activity display

Display at top shows a frequency range for rx tuning.
Red line marks the frequency the rx is tuned to.
Yellow line marks a station is active working
Green line shows station is on air running a loop
Just click in this dial and the rx will be tuned to this frequency immediately. Use mouse scroll wheel to tune values up/down.

top

Topic Transmitter

Remark: HW tx will only transmit on mf frequencies !
At 1 switch tx on/off - button will lit, tx is ready
At 2 select a frequency 410 -- 512 kHz

Two modes are available "chat" or "Audio-Morse chat" Buttons at 3 and 4 are for audio keying mode explained elsewhere
top

Topic Chat

Transmit in chat mode:

Check chat mode button at 1, HW will change from seachart to chat box
Click in to chat box and enter text you want to transmit. Chat box works like a word processing unit. You may copy text from external files and place it here. Mark your text from external, copy and paste it in chat screen. When finished ...
Chat panel keeps maximal 300 characters, extra will be discarded
Audio - Morsechat unlimited

Push button 5 go - Text will now be transmitted. HW scans through the text and transmits it and displays it in receive window 3 below. The sidetone can be muted or not by button at 7. Transmission could be stopped at any time by stop button 6.

Transmissions from other active ships will be displayed here as moving text.

Off button 8 signs off from HW session.
Docu button opens HW documentation
Chart button switches back to seachart
CLR buttons 9 wipe window

Topic More Control

1 Change to HW documentation 2 Alter audio frequency level of sidetone 3 Alter tone sound
4 Increase/decrease (qrq/qrs) speed of transmissions in chat mode
5 Alter Navigation values
Topic HW documentation  
HW contains a detailed description of how to handle the radio station at all.
  • 1 HW documentation itselfe - German version ! List more detailed - English available
  • 2 Q - Codes
  • 3 List of Radio Signals - Timetable
Timetable displays all radio signals of hw what is when transmitted.

Timetable has a 'search function' - Just check 'suchen' and enter a topic like "wcc" to get all entries of Chatham WCC radio! 		pic docu

Topic Audio - Morsechat Mode

Audio - key Mode enables you to transmit text straight out of your Morsekeyer. After some adjustments made to HW it will decode your keying and sent it on the selected mf frequency.

It works perfect, it's great, it is as real as it could be, it's like as in the old days of Maritime Radio !!

Do some adjustments in HW - train the decoder and up it goes ! Follow the 1 : 3 schematic of Morsecode, make correct letter- and word spacing. HW take the times the key is pushed and starts decoding and display your keying in rx panel.

top

Topic Wiring

General wiring : From an audio source to key to audio input of your pc soundcard
Sources may be: Audio Generater, Electronic keyer sidetone output, Ham transceiver with electronic keyer sidetone output etc
Any signal of about 800 Hz and 1 Volt level

top

Topic TX Tune

To use the telegraphy mode of HW you have to do this:

  • Toggel switch 3 from chat to key
  • Turn mic button 4 to a 3 hours position or fully clock vice
Do further settings by choice
  • Adjust 'level slider' 3 to reading approximately 172.

    • or use scope to check your signals

  • 1 Switch scope on
  • 2 Select in/out signal display
  • 3 Level adjust to detect signal / no signal
  • 4 Scope display overlay over dial panel
  • 5 Noise signal, below of level set - no use
  • 6 Level 172 line, signals above are OK
  • - This method is necessary to form square signal for HW decoder

top

Topic Train HW

Audio - Morse Chat requires a short training to recognize your personal keying behavior. The HW decoder measures times of key down and not before long detects dit and dah. Start up by keying dit - dah, v, 3, 7, dit and dah alternating.

Important:
As HW is only a machine you must give in properly signals. Best keying is the 1 to 3 ratio of signals. 1 dit time and 3 times as long dah times! Remember the words of your instructors when you start your career as radio officer

As important are the inter spacing pause times. So give letter and word spacing the decoder will work fine. Not high speed is wanted but solid keying is needed!

Using Audio-Morse Chat requires training every time you switch on. HW does not keep your personal decoding values.
