Re: How to measure current drawn by a 100w transceiver at 25w
? Howard
Your question really peaked my interest.
I remembered reading in my K3s manual that it has the ability measure the current draw. Had to go back and read the manual to determine the location of this feature.?
So here are the measurements that I made on my Elecraft K3S on 3.5 MHz using CW. You did ?not mention the mode of your operation.
Power supply voltage was 13.5 volts for all power tests, PA Temp 32c
Current draw in receive with dual receivers and connected to a logging computer via USB 1.37 amps (when PA fans on 1.48 amps)
Current draw at various output levels in CW on 3528 KHz into a 50 ohm dummy load
100 watts ?18.88 amps ?I x E = 254.88 watts ?39 percent efficiency? 90 watts ?16.75 amps ?I x E = 226.12 watts ?39 percent efficiency? 80 watts ?15.65 amps I x E = 211.27 watts ?37 percent efficiency? 70 watts ?14.78 amps I x E = 199.53 watts ?35 percent efficiency? 60 watts ?13.81 amps I x E = 186.43 watts ?32 percent efficiency? 50 watts ?12.78 amps I x E = 172.53 watts ?28 percent efficiency? 40 watts ? 11.74 amps I x E = 158.49 watts ?25 percent efficiency? 30 watts ? 10.70 amps I x E = 144.45 watts 20 percent efficiency? 25 watts ? 10.07 amps I X E = 135.94 watts ?18 percent efficiency? 20 watts ? 9.15 amps I x E = 123.52 watts 16 percent efficiency? 15 watts ? ?8.33 amps I x E = 112.45 watts 13 percent efficiency? 10 watts ? ?4.10 amps ?I x E = 55.35 watts ?(100 watt PA is bypassed at this power level in a K3S) 18 percent efficiency? 5 watts ? 3.19 amps I x E = 43.06 watts (100 watt PA is bypassed at this power level in a K3S) 11 percent efficiency?
The measured data shows the nonlinear function of a solid state RF linear amplifier efficiency verses output power.
The Elecraft K3 has a very unique feature that bypasses the 100 watt PA when operating at output powers under 10 watts. This results in a very minor increase in overall efficiency as the measured data shows. Not all rigs on the market have this capability so the efficiency will be even lower.
You did not mention the mode of operation which will have an impact on the battery life, digital modes like RTTY, FT, AM have duty cycles that can be above 50 percent , which will increase the drain on the battery.
Interesting experiment and data points.?

Howard, you’re 100% correct on the current draw versus output power.?
The current draw of you rig operating at an output power of 25 Watts is not as simple as taking the current draw at 100 Watts and dividing it by 4. This is because there are several factors that one needs to take into account.
Your current draw in receive does include things like the LCD display back lighting etc. of the transceiver. However, during transmit many transceivers, turn on additional things like cooling fans, which will add to the amount of static current draw. Plus, in the transmit mode you have a usually the output of the exciter, feeding an intermediate power amplifier that feeds the final power amplifier. Now, all of these devices in these amplifiers were chosen to make peak efficiency, at maximum output power. However, the characteristics of a solid-state amplifier when it’s not being operated at its maximum or near maximum output is that it is a lot less efficient. How much less efficient is a bit of a wild card based on the actual RF device in the circuit design.
My advice would be to operate the radio on a power supply that allows you to measure the line current as you very the output power. Alternately, if you have a multi meter that has, do you see current measuring capability, you could add that in servers to the power source and measure it alternate.?
Now speaking of battery operations you should look at your rig’s specifications to determine the lowest voltage it will operate on. After some usage, depending on the battery characteristic its output, voltage may drop below the threshold that your radio really wants to comfortably operate. My 706 begins to act weird as the voltage drops below 12 volts. My Eleraft, K3s receive an operate with the PA bypassed as low as 10 volts, QRP… ? 73? Brian?

Re: How to measure current drawn by a 100w transceiver at 25w
Howard, I was calculating transmitting efficiency, so didn't include receive current, so 20 amps is correct. I added 3 amps back at the end to get 8. I like the in-line meter with powerpoles! Even when sending CW, the duty cycle is only 50%. Add receive time during a QSO and you're down around 25%, add casual listening and you're maybe 5%. I like the LiFePO4 batteries. High capacity, lightweight, good voltage during discharge. Good luck, 73, Tim W2UI

Thank you all for your detailed responses! Yes, I wish it was all that simple. (Tim, it looks like you meant to put 23, not 20, in the formula you cited.)
What would help is if I still had my Astron RS-35M with its meters. Then I could get at least an approximation of amperage draw at different power outputs. Or, is there is such a thing as an ammeter that can be installed between the radio and the power supply? I know there is such a thing as a clamp-on ammeter, but would that be the right tool for the job? (I don’t like to “play” with electricity!)
Brian, the Yaesu FTDX10 radio draws a constant 3A with a received signal, far more than a QRP radio like an IC-705. I don’t know what the lowest voltage is that the Yaesu can tolerate. That’d be another thing I'd have to find out.?
I run both SSB and CW, no digital. At home I mostly listen. If I were out, I’d want to be making contacts. Duty cycle? I don’t know, but surely it’d be more listening than sending. I know that CW draws more than SSB. It’d be a lot easier if I just had a QRP-type radio. ?:-) But, I’d like to be running 20 or 25 watts, not 6 or 10. I suppose the easiest thing for me to do, if I wanted to operate “out there somewhere,” is to just get a 12 or 15A battery and have at it. ?
Howard ?N7SO
Hi Howard,
Must make several assumptions. The receive current is the same at 25W. The efficiency is 100/(20x13.8)=36.2%. The efficiency does not change at 25W. Therefore, 25W/.362=69W, 69W/13.8V=5 amps. 5+3=8 amps. What mode are you using and what will the duty cycle be?

Wireless On-air activities this weekend
Happy New Year ? This first weekend of the new year has a several Radio Sport and On Air activities to partake in. ? First off ARRL Kids Day. While not really a contest or radio sport is it an event that encourages you to promote our hobby to youth. Share your hobby with your Kids, Grandkids, Church group, Scout, friends children etc. ? Complete details are at ? Remember to review the FCC rules on “Third Party Traffic” as current band conditions are favorable for DX contacts. ? ? The ARRL RTTY Roundup is happening starting at 18:00 GMT (1 pm local) Saturday January 4 thru 23:59 GMT (6:59 pm local) January 5 ? Never tried RTTY? The ARRL RTTY Roundup offers a great playing field to learn a new mode. Chances are that you are already doing FT modes so shifting to RTTY is most likely setting up your digital software to do RTTY. Contest logging software like N1MM (free) supports the ARRL RTTY RU has the MMTTY engine as well as FLDIGI integrated. ? A good website for RTTY operating tips is ? Here is a link to a presentation on RTTY contesting that was given at a Yankee Clipper Contest Club meeting by Ed Muns W0YK ? So basically, Amateurs worldwide contact and exchange QSO information with other amateurs using only the Radioteletype (RTTY) mode on the 80, 40, 20, 15, and 10 meter bands. Any station may work any other station. Stations may be worked once per band, regardless of mode. Automated operation is not permitted, each claimed contact must include contemporaneous direct initiation by the operator on both sides of the contact.? ? The Exchange for US stations is our state, VE stations their providence and DX stations will give a serial number. ? This is a typical contest contact: CQing Station: CQ RU DE NJ1F Answering Station: W1UE CQer: W1UE 599 NY Answer: 599 MA CQer: TU RU DE NJ1F ? ? Calling a station DX CQ looks like this CQing Station: CQ RU DE SP9KR Answering Station: NJ1F CQer: NJ1F 599 231 Answer: 599 NY CQer: TU QRZ SP9KR ? ? You can operate a max of 24 hours out of the 30 hour contest period. ? Complete rules at ? Band conditions have be fantastic to really bad. There are several very active sunspot regions facing Earth that have sent CME’s and solar flares which have wreaked havoc with the bands. Space Weather is predicting a glancing hit of a CME this weekend . ? THE NEXT STORM IS COMING: NOAA forecasters have issued a -class geomagnetic storm watch for Jan. 4th and 5th when a CME and a stream of solar wind are expected to graze Earth's magnetic field. This should be a relatively minor event, much less intense than the severe -class storm of Jan. 1st. Nevertheless, high-latitude sky watchers (especially near the Artic Circle) could get a good show if the storm materializes ? ? Hey the next Club meeting on Monday January 13th will feature Fred K2TR interactively sharing his years of experience of HF and VHF propagation, answering questions ?and sharing propagation sites / tools. ? A friend W1VE will be operating in the ARRL RTTY Roundup as 7Q2T (Malawi) doing single band 10 meters. Tip I worked him during the recent ARRL 10 meter contest at 18:30 GMT with 100 watts and a dipole, so that would be a good time to look for him on Saturday or Sunday. ? ? Hope you get on your wireless set this weekend. ? 73 Brian NJ1F ? ?
