microHAM ARCO Smart Antenna Rotator Controller

0

In recent years, amateur radio station management has evolved greatly with computer aided systems. Many ham radio operators effectively work remotely and can even control their entire station from their own PC. With this in mind microHAM, a pioneer in the development of integrated radio-PC systems, has developed  “ARCO“, a rotor controller device that has innovative and unique features.

ARCO is a fully autonomous rotor controller with a wide range of remote control options. It controls azimuth adjustment through an intuitive graphical interface and a 7-inch touch screen that can be customized by the user in terms of color, automatic day/night variation, display of the globe in grayscale and more.

Positioning of the antenna can be done by simply touching a point on the displayed globe or one of the proposed ITU prefixes, but also by using the classic CW-CCW keys or even by entering the position via a virtual keyboard.

For remote management, there are several connection options: the classic USB port with COM emulation (no driver required for Win10, macOS and Linux), the RS-232 serial port and the Ethernet port for Internet connection.

Boxed into an all-aluminum enclosure, the unit can be configured through simple menu functions, allowing it to be easily connected to any type of rotor, commercial or even homebrewed, and guarantees longer life through gradual control of the start and stop speed in case of strong wind gusts or ice on the antennas.

For complex antenna systems, there is a local connection between several ARCO controllers via a two-wire bus connection for directional masts, rotating towers, etc. Even remotely several ARCO controllers, located in different parts of the world, can be synchronized each other via the Internet with a very simple procedure.

MicroHAM will ensure continuous implementation of functionality through the development of free downloadable firmware.

Yaesu FTM-6000 Dual Band Mobile Transceiver

0

The  new  FTM-6000 R/E   is  a  basic  feature  packed  mobile  transceiver  employing  a  new  User  Operating  Interface  –  E2O-III (Easy  to  Operate  –  III). The  FTM-6000  delivers  reliable  and  stable  50W  transmit  performance.   

The  heavy-duty  heat  sink  is  equipped  with FACC (Funnel  Air-Convection  Conductor).      

The  speaker  delivers  3W  of  clear  and  crisp  receive  audio  which  has been  specifically  tuned  for  radio  communication.    

The  front  panel  of  the  FTM-6000R  is  detachable  and  can  be mounted at  the  most  desirable  operating  position.   

The  new  FTM-6000  supports  optional  Bluetooth®  wireless operation  using  the  SSM-BT10*  Headset  or  a  commercially  available  Bluetooth® headset*.   

E2O-III  provides  three  user-intuitive  operating  modes  to  assign  functions  and  settings: 

  • The  most  frequently used  function  can  be  registered  to  the  “F1” key  and  then  recalled  with  a  single  touch  of  the  F key. 
  • Other frequently  used  functions  can  be  assigned  to  a  Function  List  and  then  recalled  by  simply  pressing  the  “F  Menu” key and  rotating  the  dial. 
  • All  functions  and  items  other  than  those  registered  to  “Most  frequently”  or  “Other frequently’, are  selectable  by  pressing  and  holding  the  “F  Menu”  key  and  rotating  the  dial Up  to  5  channels  can  be  registered  in  PMG  (Primary  Memory  Group). Frequently  used  PMG  frequencies  can  be shown  in  an  easy-to-  distinguish  display  just  by  pressing  the  “PMG”  key.
FTM-6000R

The  MAG  (Memory  Auto  Grouping)  function  automatically  groups  memory  channels  so  they  may  be  easily  recalled by  band:  All  memory  channels;  AIR  band  (108MHz  –  137MHz);  VHF  band  (137MHz  –  174MHz);  UHF  band  (400MHz –480MHz);  and  other bands  (174MHz  –  400MHz  /  480MHz  –  999.995MHz).   

The  new  FTM-6000R  VFO  Band  Skip  Function  permits  unused  bands  to  be  skipped,  while  the  registered  memory channels  can  be  recalled;  even  if  the  frequency  is  in  the  skipped  band. By  pressing  “SQL  BACK”  key  when  the memory  channel  is  displayed,  the  contents  of  the  currently  selected  memory  channel  can  be  transferred  into  the  VFO register.  Depending  on  the  operating  situation,  either  the  VFO  or  Memory  channel  operations  are  separately  useable.    

Some  of  the  other features  of the  FTM-6000  are: Wide-range  receive  coverage  from  108MHz  to  999.995MHz; 1100  Memory  channels  with  alphanumeric  tags;  supplied  DTMF  microphone  –  SSM-85D;  Scanning  Functions  –  VFO Scan,  Memory  Scan,  PMG  Scan,  Programmable  Memory  Scan. 

Special Event 75th Anniversary NCDXC

1

On October 10, 2021 the Northern California DX Club will celebrate our 75th year! To mark this milestone we will hold an HF Special Event on the weekend of October 9th and 10th, 2021.

Using our call sign W6TI we can be found operating on bands 15, 17, 20, and 40 meters and using SSB, CW and FT8 modes. The festivities begin at 16:00-23:59Z October 9th and continue 16:00-23:59Z Sunday October 10th.

A special QSL card will be available upon request.  QSL details at W6TI on QRZ.com.

Since October 10, 1946 the Northern California DX Club has been dedicated to the finest ideals of good DXing, raising the standards of Amateur Radio practice and ethics and interactively sharing knowledge and information to enhance and benefit the Amateur Radio Community.

NCDXC has co-hosted the International DX Convention for over 70 years.

73 & Stay Safe,

WSJT-X 2.5.0 New version available!

0

 

WSJT-X 2.5.0 introduces an enhanced Q65 decoder that measures and compensates for linear frequency drifts of Q65 signals.

Activate this feature by setting a spinner control Max Drift on the WSJT-X main window to a number greater than 0.

We suggest a setting of 10 for submode Q65-60A, the recommended submode for EME on 50 and 144 MHz, which will accommodate drift rates up to 20 Hz/minute. Similarly, we suggest Max Drift = 40 for submode Q65-15C, used for for 10 GHz QSOs (up to 900 km) via aircraft scatter and drift rates up to about 20 Hz/s.

On the Windows platform only, WSJT-X 2.5.0 installations now include MAP65 3.0. This program works together with suitable hardware that converts RF to baseband.

The hardware/software combination implements a wideband, highly optimized receiver for the Q65 and JT65 protocols, with matching transmitting features that require a standard SSB transceiver.

MAP65 is effective in both single-polarization and dual-polarization systems. If two polarization channels are available, MAP65 determines and matches the linear polarization angle of each decodable signal. This capability provides a major advantage for efficient EME communication on bands up to 432 MHz. A single-channel MAP65 system works extremely well for EME on 1296 MHz and higher bands, displaying all signals in a 90 kHz sub-band and decoding all the Q65 and JT65 signals.
