Another thing @Northof62, for the dummy load, you want one without meters that covers 0 to 600 MHz. Ultimately, you will need two external power/SWR meters, one for HF and one for VHF/UHF. For now, if you don’t own any power/SWR meters, we can use the internal power and SWR metering functions of the Yaesu FT-991A.

As for a dummy load, it should have an SO-239 connector and be rated at 300 Watts intermittent or 1,500 Watt intermittent. I prefer a 1,500 Watt dummy load for my 100 Watt and 250 Watt transceivers because the transmitter can be held “key-down” almost forever.

Using DX Engineering as a Reference, here are the dummy loads:


I would suggest either the MFJ-260C for $70 or the MFJ-264 for $130. Both are adequate for your “barefoot” transceiver. As I said, I would prefer the MFJ-264 because of its power handling capability.

Thanks! I will look at those today.

I want to thank you guys for all your help. I'm very appreciative of you taking the time to help with what turned out to be a very simple fix. My friends radio had a tone set which wouldn't allow me to break though. I couldn't reach my HT because it was to close to my Yaesu.

Big thanks to Ric KC5AKB who contacted me last night and figured this out for me.

There's so much to learn about this hobby and I'm at the very beginning. It's nice to see there are so many people willing to share their years of knowledge.

Thanks!
Glad you got the VHF/UHF side going! All of my comments still apply as you get set up to operate on 10 Meters.

P.S.: I didn’t think that the transceiver was defective…

Overload and Tone. lol yep a 991a will overload a HT and tone will prevent reception.
