Making Simple EH 27 Antena for 27mhz

Today i will share how to make simple EH 27 antena for 27mhz or 11 meter band, let's  see below for simple schematic EH 27 home made antena.

Fig for EH 27 Antena

SWR Testing on frequency  27.105 Mhz to 27.605 Mhz with 25 Watt power  from CB radio :

                                                   EH27 ANTENA SWR POWER TEST

                                             EH27 ANTENA  SWR TEST  1:1:0 VSWR



Ok Everyone, that's all I can tell about  homebrew EH 27 Antena for 27Mhz, and please rest you modify the antena by yourself to be better and better until get very good SWR. thanks and happy homebrew experiment.... 73's....

CB 26-28Mhz HomeBrew HF Booster With Single IRF540N

Hallo my Friend around the world.., today just wanna share CB HomeBrew HF Booster 26-28Mhz.

 REV.1  ( With Trimer Capacitors )

REV.2  ( Without Trimer Capacitors )

Please Download here for best quality shcema

This booster CB for 26-27Mhz schema, using power IRF transistor, for lower cost your experiment. and

more easy to adjust RF power. in this schematic, i am using IRF 540N , it can be made power output about

50 until 60 Watt For normaly DC consumtion 12,5 - 13,8 volt. for bias G (Gate) for this IRF transistor, i am using 1,5 until 2,2 Volt for safety the IRF transistor. please make sure the G (Gate) bias voltage (Set to 1,2 Volt) before your conect IRF 540N On the PCB. For C (Condensator) Couple on Input and Output , you may using Trimer capasitor or Fixed capasitor. for best quality power output and impendance, i recommended using Trimer Capasitor for easy adjusting Zi and Zo until best power and good impendance 

(50 Ohm).

 *Note: For Reading coil Turning

eg. : 7LD6m.mW0.8m.m  =  7 Turn , Diameter 6m.m , Wire 0.8m.m

Ok Everyone, that's all I can tell about my homebrew CB HF Booster, and please rest you modify it yourself to be better. thanks and happy homebrew experiment.... 73's....

My Little QRP Station

Hallo every one, my name is Egi Noerman Van Beekom / 91NR146 division from indonesia. that is my little QRP stations in my home. i like to using this old version QRP 27Mhz CB  radio because it makes a challenge for me for re-modification this radio and to communicate friends around the world with low power RF output maximum only 15 Watt. I am so..so happy!!

For Now i am using 2 QRP 27Mhz CB radio, its that :

1. First I am Using COBRA GTL 150 120 CH SSB 27Mhz SSB Radio
 

  For COBRA GTL 150 120CH Specifications :
@ Freq Band  LOW-MID-HI  ( Band B-C-D )
@ Mode LSB-USB-FM-AM
@ RF Power 15 Watt on LSB and USB and 9 Watt on mode FM-AM ( After Modifications by Self )
@ DC Power 12,5 Volt
@ Made in USA

2. Second I am Using ARIES SUPER 120 (Made in Indonesia) SSB 27Mhz SSB Radio

 For ARIES SUPER 120 (Made in Indonesia) Specifications :
@ Freq Band  MID ( Band C )
@ Mode LSB-USB-AM
@ RF Power 15 Watt on LSB and USB and 4 Watt on mode AM ( After Modifications by Self )
@ DC Power 12,5 Volt
@ Made In Indonesia - in 1980

Well, until now i am so happy and satisfied to using both of this Old Version 27Mhz CB Radio, i love that modulations sound after re-modifikations by self...so satisfied.. QSL!!
