I need to file a complaint with the board of education specifically the geography dept. I was lied to. They taught me the Mississippi ran down the center of the country. 😂😂😂😂
Thanks for the kind words! Happy to help and share!
Thanks for the kind words!
Mississippi River from LA to Ft. Lauderdale? Yer killin' me Smalls, yer killin' me.😂😂😂
You can learn all about geography here on Ham Radio Tube!
Mike, thanks for answering my question on data modes on QRP vs QRO. Your gasp for air is a helpful reminder that I am verbose :)
Mike, good analogy regarding the power output of the radio. Just because you can operate at 100 watts doesn't necessarily mean you should.
How does the Mississippi go uphill to get over the Rockies one might ask? Good question.
The answer is: volume. It's really simple economics when you break it down, scientifically.
Great video Mike! 👍🏽
Thanks, excellent information!
Thanks Mike. Good info. I'll leave the 28w panels along and use them to run powerbanks. I dohave 160w ecoflow panels. I'll try with that one
My understanding is that the Xiegu G90 uses 2 Mitsubishi RD16HHF transistors in the finals (or at least, they used to; haven't opened mine up to look). Each is capable of handling 16W-20W. So routinely using full power should not be a problem.
The G90 is a beast!
I run my 100w radios at 50w, unless I am working my local OM net on 80m, where I drop to 10w.
Oh, Pintos did not blow up from revving the engine. It was from cracked fuel feeds leaking gas everywhere.
Good afternoon Mike thanks for sharing this video I always enjoy mailbag Monday but when did the Mississippi River get diverted to the everglades?
I figured Mike was trolling waiting for all the comments stating the Mississippi starts in Minnesota:)
On the power question, the major issue is heat. Electronic lifetimes are significantly diminished by heat. If you run full power on FM or digital with a high duty cycle, the finals and other components will be running at their highest temperatures. As you allow that temperature to rise, the lifetime of the components is reduced. If the rig is in the sun, or the airflow is blocked, the lifespan can be drastically reduced quickly. Therefore, running for short periods of time, or a low duty cycle, at full power is not a big problem because the temperature stays low. If you put the radio in a bag, or deep inside under a shelf, or on the dash in your car, you will be shortening the life even at low power levels, because the temperature can rise too high. So, it is good to run lower power levels and keep the heat down, and try to be conscious of how hot the rig is getting. Run even lower power if out doing POTA or FD in the heat, and worry less about it when conditions are ideal.
With the whole power thing, that's why I have heard with amps you get a larger wattage then what you want to run. If you want to run 500 watts you should get at least 800w or if you can afford it 1kw but run at 500w and it should serve you very well for a very long time since you are not putting a heavy strain on it.
For POTA, yes let the DX know AND move them up/down to work them!
I also run my x5105 at 5 watts. Use a compter fan on it radio will not get hot. Less stress. 😊
I ran into a similar situation with a domestic station. Was I there first? Was he there first? I couldn't say for sure. Knowing that I did have my required QSOs, I moved and went P2P hunting.
K Murder is my favorite Tom Sawyer floating down that mississipp
Small data point but my g90 does almost exclusively ft8 @20.3w and I’ve yet to have any problems 😊
Interesting, I was actually wondering if CW was as bad as data for the radio. Good to know I can floor it! :D
Cw has a lower duty cycle than data. Data is 100% duty (continuous) CW about 30-50%.
If data then run around 25-30 % of max peak. Eg if tx rated at 100W peak- use 25W for data

@@DavidCase-ov5uo well, thanks heaps for that!
Another great video, however, some radios (yes it’s the exception) like the QRP-Labs QDX is designed to operate at its full 5 watts at digital. Jerry KB2GCG
I love Pata even if it is the same park I go to.
I run my ft817 full power. I put a Cooling fan on it.
Several times when doing POTA activations on CW, I'll be 10 minutes or so into my activation, get people tuning up on me, not call me. Then someone call QRL? and then start calling CQ right on top of me...drives me up a wall.
Bioenno told me that it is fine to chain their solar panels of varying wattage, as long as they are similar type, for instance a BSP-40-LITE and a BSP-60-LITE are ok together, a BSP-28 and a BSP-120 are ok together, but a BSP-40-LITE and a BSP-28 are not ok together.
The system will always default to the lowest voltage or lowest amperage panel, so a 60 watt and 100 watt together will effectively be 120 watts (60x2)
Personally? If you aren't stepping on the other guy, zippering comms is fine with me. Works for cars and airplanes, can work for Hams
Hello Mike, will you be interested in Maono audio products?
Sure. You can contact me over email k8mrd@icloud.com
60% of the time it works every time
If the panels have reverse voltage diodes, then different wattages should be okay. The issue is one panel feeding voltage into another if they have different outpoot voltage curves. Be careful, though, and check with the manufacturer. Carbonized toys lead to wailing and gnashing of teeth. As always, do your homework. Like you, I am a solar nut.
The Bert and Guinness!
