Dennis, Nice review, however, please according to LDG, there is no by-pass mode on the RC RT 100 tuner. Per LDG, when power is removed from the tuner, the relays remain latched at the last frequency at which the tuner was tuned. The manual indicates that in order to latch the tuner at what is effectively a "by-pass" status, one should connect the tuner to a resonant antenna and run a tuning cycle at the resonant frequency. Both of my MFJ autotuners allow front panel selection of the bypass state, achieved by powering the tuner off. When tuned for use on a significantly different frequency, the received signal is significantly attenuated. In order to eliminate the received signal attenuation, i select bypass.by turning the tuner off
How did you determine that the SWR was "reading higher"? I'm a new general and trying to figure out there things...thanks for the videos. Also, I was told not to tune up on popular POTA frequencies? Any way to explain that?
Hi there, I heard someplace else that you can directly connect the remote tuner with the FT-891, put the radio in ATAS mode, and then use PTT+Up to trigger tuning, and bypass the external box. Have you tried this yet?
This works perfectly. So for portable work, you can leave the bias-t box at home, along with its power cable and the coax jumper required to connect it.
I have a 10 meter invertred dipole on a second floor apartment balcony. The shack is the master bedroom. Where do you recommend i get my ground? No earth nearby and equipment located across the apartment, not convenient to ground to. Instructions don't elaborate on options. By the way I love your videos...thank you and keep making them lol!

That's a tough one and my answer will be controversial to some. If you can get a #6 wire to a copper cold water pipe that in my opinion would be the best. The other option is to tap into the 120v ground, buy a 3 prong plug from a hardware stored, only hook up a #12 wire to the ground, not Ideal but better than nothing. Lastly if the building has a hot water heating, hook a wire with a clamp to a radiator, I did this when I lived in an apartment. 73 Denis
@@VE3BF Thank you! I love the LDG rt/rc 100. I was able to make a contact on 40 meters from my location in Huntsville Alabama to Massachusetts 1150 miles away! To think that possible on 40 meters from a 10 meter dipole on a second floor apartment is amazing! My SWR was about 1:3 with only two watts reflected. My SWR was actually lower than on 20 meters! I really appreciate you taking the time to help me. I will most certainly look into the 120v ground option as this is the closest option I have! Thank you again! W2JDP Joe 73's
@@VE3BF Dumb question, but regardless of the power used to tune will the SWR remain the same from say 30 watts to tune at a lower power and then go up to 100 watts?

Oh, that's kind of an advantage of the MFJ TUners then.
Nice real use review Dennis. I chose the SGC-230 tuner for my FT-891 as I wanted less boxes to attach
I am really worrying about the radio during the tuning sequence with HiSWR most of the tunning time...

I see the clip is connected to a ground wire. Where is that wire grounded to exactly?
Great video, well done from VK land.
It looks like your ground wire is just connected to your radio. Was your radio grounded to a real ground?
Hi, wondering if you are still liking that tuner? I am thinking about buying one. Rick (WB4MRW)
Very nice review and demo. Thanks! 73 de Jeff, KF5KWO
nice review but I'm so glad i didn't get one of these
What antenna are you using and how is this all attached to your mast ?
Would the tuner work in the mobile?
When you tune up, do you lower the output wattage? Then turn up to the power level you need? Thanks, KD4MAN
This tuner can safely tune at 100 watts but it's always a good idea to lower the power when tuning, it's easier on the radio finals.

I have that tuner. It lived a year and then died.
Contact LDG the tuner has a 2 year warranty. VE3BF
@@VE3BF I will. Just not too motivated to climb up on the roof to take it down.
Seems super complicated to use your radio.
He was certainly NOT, "5 and 9" more like 3 and 5. So annoying to be lazy on signal reports...
