How to use your Yaesu FT-710 with an MFJ-939 Antenna Tuner. MFJ-939Y Compact IntelliTuner MFJ-5114Y

Hello KZbin! W6OBB here. Here's a short video where I show how to use Sticky Mode on the MFJ-839 Antenna Tuner as the External Tuner option build into the FT-710 doesn't work with the 939. Thanks for watching and enjoy! Please follow! 73 de W60BB

Thanks for the info, because I'm leaning heavily towards buying one of these -- unless there's a newer hotness shown off at Dayton this week! So buy week after next. Also, congrats on gettin Art's old call sign. Really miss the guy.

I mainly use it for portable, SOTA/POTA now with my 891. The thing has been bullet proof. I through it in my back pack and it's all scratched and dinged up and still tuning for me. Thanks for watching! 73 😁

The 939 is the BEST auto tuner out there!

[@dennisvoorhees6763]

Thanks for this. I have the subject radio and tuner. My biggest complaint with the 710 is the tuner doesn't work a very wide range and requires constant retuning. The MFJ is very fast, if you don' t consider switching the radio to AM. however a much wider range and good memory retention. Also, it tunes my end fed 40 meter antenna on 80 meters, and WARC bands. Yeah maybe not all that efficient, but i also have antenna restrictions.

[@W6OBB]

Yes, it works great on WARC bands w/ an EFHW. I bring this with me now on SOTA and POTA with my FT-891 and an EFHW and it's worked great on 17 meters. I've also made a few contacts on 80 with it. Thanks for watching! 73

With my IC-7100, it will tune on 6m. it just complains because it has no memory capabilities, sometimes I have to retune a second time, but it works =)

[@gregmacklem]

I am new to HF and have the Yaesu 710 and I am trying to figure out when you need the external tuner vs. the internal tuner?

[@W6OBB]

The internal tuner tunes an antenna up to 3:1. If the SWR is higher, you need an external tuner. This MFJ tuner does Matches 6-1600 Ohms (SWR up to 32:1). However, I'd recommend getting an antenna that is a close to resonance as possible. I actually have needed the external tuner with my EFHW antenna. I use this tuner when portable now for POTA or SOTA with my FT-891 as it doesn't have an internal tuner. It works great for my 891 when I want to use my 40-10 EFHW on 17 meters. What's your call sign, BTW. 73 de W6OBB

[@genie555m]

Has this been fixed yet? also what setting should it work with in the FT-710? I'm trying to interface an MFJ-993b via the MFJ-5124Y to FT-710. No luck so far.

[@W6OBB]

I actually ended up not using with my 710. I played with it a bit, but I have turned it into my Tuner for doing SOTA and POTA with my 891 and it works great. I'm not sure about the setting.

[@thomashenderson603]

Are there any tuners that [play well with the 710?

[@W6OBB]

Yes, the LDG tuner is supposed to work just fine.
