I'm not using that configuration at the moment. I'm using an MFJ-993B. It has two power and tuning ranges. On 150 watt scale, it tunes 64:1. On 300, it's 32:1. I'm testing it out.

All you need to do is throw a 10 watt carrier and do a tune. Once your memories are built up, SSB peaks will instantly tune. Or, you can just throw a carrier and do it.

So it acts like a LDG Z11ProII and has the automatic with keyup. I have about 60 memories I use currently for my nets and active frequencies. This would work well then once saved in and locked and tuned.

This 891 sounds like it would make a good base setup for me and fit in my tiny shelf.

It works the same. I don't like how Yaesu interfaces with MFJ and LDG tuners. I put my tuners out of reach and don't like having to putshthe tuners button. On my Kenwood and ICOM's, I use the cable. The main advantage of MFJ tuners are in their tuning speeds. They tune unknown impedances much faster. The wider range is nice, but not needed by everyone. Several MFJ tuners have built in meters. LDG had a meter for the 600 watt and up units. I don't know why they stopped making them. IDK why, but I have RFI issues with LDG tuners. Many times, I'll get a targeted match, then while transmitting, the tuner will keep going into tune mode. I've never had this issue with any of the MFJ units.

Some people turn their head at MFJ. I've had decent luck with their various products. Not once did they ever not make it right. I always pull the top and carefully inspect for QC issues.

There are 3 (!) different tuning modes on the LDG
Manual, "semi" manual, and full auto.

the "semi" setting initiates a tune cycle only when your PRESET swr setting is exceeded.

Pretty sure Johnny is a member here... he makes some great videos. For base station use, I'd definitely recommend going this route:

You can select ATAS in menu and intiate a 10 watt carrier to tune. Press and hold PTT, then push and release up button. It will key 10 watts. Release PTT when done.

Ordered one. Couldn't resist the DARK SIDE. Saved $12 with an abandoned cart coupon from Giga. Picked Fed Ex Ground. No payments till May 18th. (That's when my recently paid off CC comes due with this on it). (y)

The 939Y tuner availability dried up some. Grabbed up from DX. :)

Tune button won't do anything unless you have an ATAS, I do believe. If you use an interface cable, I believe you must push tune button on the tuner itself. Use the mic method to throw a 10 watt carrier.

  • No one is chatting at the moment.
  • @ ButtFuzz:
    on the connector with the green wire, if you short that to a nearby black wire, the power supply will turn on. (for use as a bench supply or whatever)
  • @ ButtFuzz:
    And IIRC, the purple wire is -12VDC, but that is from memory and it does not serve.
  • @ ButtFuzz:
    So if you need, say, 7v, connect + to the Yellow wire and - to the Red wire.
  • @ ButtFuzz:
    or or you need 9v connect + to the yellow wire and - to the orange wire. note: not all PSU's have the orange wire nowadays, as many manufactures had the voltage regulation on the motherboard, and all the power supply gives is 12 vdc
  • @ BJ radionut:
    Thanks ROB will check it out!~!! got to clean the work bench a little make room for that big case :)
