Switching on the 10db attenuator decresed the S-meter readingīy around 1 S-unit, and switching the 20db attenuator in reduced the S-meter The S-meter reading increased to between S8 and S9 on switching on the PREAMP Into a 2.4KHz bandwidth is -105 dBm or 1.3 microvolts. The approximate output of the Elecraft N-gen
The S-meter read around S4 on the LF bands and around S3 on the HF bands with OFF), except on 24/28MHz when it was necessary to switch the PREAMP ON to Metal screwdriver blade to the inner conductor of the antenna connector (PREAMP Noise level increased slightly when touching a Less, almost negligible, effect of the NB on the ambient noise from the With NB on, spike meter reading did not exceed S3-4. With NB off, I could see noise of up to S9 registered on the S-meter when the The antenna socket and hung around the lamp, switched on and off. (China made soldering lamp / magnifying glass). Has some effect on noise induced from switching on a nearby fluorescent lamp In the high power (100 watts) position, power output varied between 107 watts and 120 watts depending on the band. Transmit S-Low position (nominal 0.1-2 watts, actual 1.45 watts) 3.47 amps (7 MHz FM) Transmit Low position (nominal 10 watts, actual 12.5 watts) 6.48 amps (7MHz FM) Standby 2.28 amps (7MHz SSB, did not change when Low or S-Low selected) Model is the DX-SR8E or ‘European’ version.Īll measured at 13.8V DC supply to the radio.Ġ.68 amps (7MHz SSB, background noise, squelch off) Power measurements using a Fluke RF probe/Bird attenuator and 50 ohm resistive load.
The following are DC current draw measurements taken using a Fluke meter. Also note the very QRP output can be changed as noted below. I would note the final comment below in my original post about how to change the output to 50 watts from 100 watts.
