Optimizing the FT-1000MP with the Heil Goldline info provided by Andy, KK7AC

I have had the 1000MP since January of 1996. I have had several "top line" transceivers in the past; 1000D, TS-940, 950SD. I got to love the MP not only for its wonderful receiver, but for it's transmit audio in DSP that not everyone at the time seemed to unlock or was aware of. I am not an expert in audio or RF design, however, I have a pretty good knowledge of the transmit settings on the 1000MP, and I know and enjoy good "studio broadcast" audio on SSB.

In the beginning: I always stuck with my trusty old Astatic D-104 amplified microphone as I did in all the Yaesu equipment I ran. Yaesu equipment tends to need either:

1. - an amplified microphone with the processor OFF, or
2. - a non-amplified microphone with the processor ON.

I and another good friend (KX9T) bought our radios at nearly the same time. Since we both had and ran the D-104, we decided to "try it out" on the MP. After about a week of playing with the DSP settings, we found the MP and D-104 was an excellent combination!! It was not as you may think of your typical D-104 sound. You know the rusty, high pitched, full throttle compressed audio that makes your ears bleed. Great for CB's, and the last hour of the CQWW, but everyday rag chewing? No way. This was not the case however with the MP and the D-104 combination. It was this "new" sound. Kind of "bassy", but still fidelic. I don't claim to be the first person to "unlock" the secrets of the MP in relation to TX DSP, or the first one to have this type of audio on SSB with any transceiver for that matter, but man did I ever get the audio comments on the bands. Never before did anyone stop and say
"Man you sound good, its kind of bassy, but you have the highs also, I don't how how to describe it": "What kind of microphone is that?": "What is the rig you're running? It sounds like you're on AM." These are just a few of the comments. The real fun began once I told them what I was running: "A 1000MP with a D-104? That's impossible!" "You cant run a D-104 with a new 600 ohm radio, it's a mis-match." "That's not a D-104, it's too bassy". So for
nearly 3 years, I ran that old D-104 and MP combo. It sounded great, and "we were of the select few", but in early 1999 SSB audio took center stage with a lot of hams. More and more hams where on the experimental bandwagon with both DSP, and using different microphones.

The switch: My XYL bought me a Heil Goldline Studio microphone for my birthday in November of 1999. I did not expect to receive this, but I thanked her just the same. I had not heard too many on the air, so I did not have much of an opinion on them. I hooked it up as described on the owner's manual. This did not work out at all!! Audio reports where going from great on the D-104, to "flat bass no highs" audio. How is this possible? The response on the Goldline is 50-16,000 Hz, not 1000-2000 on the D-104! Well, after being beat up on 14.178, I was in shock. After altering the settings that I ran for so long on the D-104, I still could not get the audio to "brighten up" - it was just flat. Then after hitting the processor button while listing on the monitor, I fell out of my chair! The processor was the
key. That's what was needed to bring up the audio.

Again, I am not an expert in the field, but I will give you some great advice in the SSB audio field as it pertains to the MP with nearly any microphone. I do not run any external equalization, noise gates, compressors, or audio amplifiers. This equipment is necessary if you run an older radio that does not incorporate DSP. The DSP equalization in the modern radios is great, and don't waste your time or money on outboard gadgets if your running the MP or any other wide transmit bandwidth DSP radio. You will go nuts, and the gains that you will achieve may not make you completely happy after spending $5000 on this crap.

The two things you need are:

1. A good (not necessarily expensive) microphone with a wide response. (40 to 18000 Hz).
2. A modern HF transceiver with DSP equalization in transmit.

If you are running the MP, and have a Heil Goldline, DO NOT FOLLOW THOSE INSTRUCTIONS!
Bob has you running the OFF position in menu setting 4-4. That's wrong! Below are the settings you should start with. I have talked to Bob about this already, and I believe that the newer microphones now being sold contain a revised "manual" and the settings below are in it.

4-4= 3 always - every good sounding MP I've heard runs "3"
5-9= 6.0 kHz (t-Fil) always
7-7= 100-3100 (SSb-t) always
8-9= Proc - Lsb *0.040 + or -.040 (* adjust depending on voice)
Proc- Usb *0.040 + or -.040 (* adjust depending on voice)
t-LSbcAr -0.200 always
t-UsbcAr -0.200 always

(N1EU note - 8-9 menu settings have no effect in the MP if EDSP is switched on)


**NOTE: Proc settings are the only two you use to adjust the audio now. The higher the setting the higher the frequency response. My voice is already fairly deep, so I use "Proc" in both sidebands in the 0.070 range. Others that need the lows in the audio chain because their voice is higher, or does not have lows in it, need to consider starting in the 0.000 range, maybe even lower?! P.S. I found that the Goldline mic doesn't do to well on FM or AM.
If you know the secret, let me (KK7AC) know. Till then I will run the D-104 on those modes.

An MD-1 or MD-100 works well with the same settings with the processor on.
