1.Turn on/off switch
2.Auto receive/transmit switch
3.Electrode reversal protect
Frequency range: HF(HF Amplifier best effect Frequency range:20-30mhz.( Works on 15 meter, 12 meter and 10 meter)
Input power SSB:2-10W
FM Output power:PEP Max 150 W(Input 10W)(Note: Note:Normal the output power is 70-100W)
AM Output power:PEP Max 150 W(Input 10W) (Note:Normal the output power is 70-100W)
Output power SSB:300 W(Input 10W) PEP Max 250W (Input 5W ) PEP Max(Note:Normal the output power is 120-250w)
Working mode:FM- AM-CW-SSB
Note:if you will test the max PE power to FM/AM 150W or SSB 300w,you can try use input 10w from FM/AM /SSB radio but please don’t use too long time, the operate will cause damage to power transistor, more serious will cause the amplifier to burn out.
Blown fuse:2×12 A
Compact high power all mode amplifier with
automatic TX/Rx switch and On/Off switch. Electronic switch.
Inversion polarity protection.
Packing Incudes:1*TWAYRDIO TW-300N Amplifier
- TWAYRDIO TW-300N HF Amplifier best effect Frequency range:20-30mhz.( Works on 15 meter, 12 meter and 10 meter).
- Operate voltage 13.8Vcc.Input current/POWER:14-20 A. Input power(FM/AM/CW):3-5 W Input power (SSB):2-10 W. Compact high power all mode amplifier with automatic TX/Rx switch and On/Off switch.
- HF amplifier bellow 20Mhz the output power will be lower and vswr will be higher than 20-30Mhz.Connection of antenna is very important for low frequency product , the effect of the antenna will seriously affect HF amplifier effect.
- New design, adding an external fan can also cool the amplifier, this is low frequency amplifier, the high power output will cause to amplifier internal heat, so the mini fan will give amplifer best help, which can extend its life.
- The amplifier different model ,such as FM,AM,SSB,CW. Please learn about how to operate when you want to purcahse. Or ask for us and give professional advice.
