CYBERMAXAM+ BE 10W/100W/250W DRM MW/SW transmitter (ID: 86502)

Description

DRM MW/SW transmitter 

COMING SOON – DESCRIPTION NEEDS TO BE UPDATED

While for many mentioning AM transmitters brings back childhood memories, these are actually still used widely in some countries. Besides, AM can be lots of fun to play with. Long wire antennas, different signal propagation (even worldwide), the nostalgia that comes packed with it… well, it is something very different in this modern age.
Our old AM MAX units sold out many years ago and for a long time we wanted to make a new AM transmitter, this time with different, more modern approach, with new better parts and better specs. And we finally did. It is equipped with DSP which makes it possible to control parameters of the audio chain, such as the compression, low pass audio filter cut frequency and preemphasis via convenient LCD with menu system. Other features, such as the fully solidstate PWM modulator which ensures crisp audio, 125% positive peak modulation, compact form factor, plenty of audio input options and LCD display unit make AMMAX8000+ really something special in this modern age.

Bazooka wire dipole antenna:
This is a very good solution with one major drawback, it is quite long. Some 95m long at 1500KHz. To erect such an antenna you will need several support points (poles) to hold it in place. Otherwise it can’t carry its own weight. Also, in the middle is antenna connector and this will need to be supported as well. So  expect to need at least 5 support points/poles. This antenna can perform  quite well. For best results consider planting a ground wire or several wires exactly below where the antenna is erected. Connect this ground to the antenna ground (coax shield).

Radiation resistance:  50 OHMS
Connector: SO-239
Frequency: Specify at time of ordering
Maximum output power: 2000W CW
Weight: ~6Kg for 1800KHz
