Re: Proper battery

 

Hi
The 4.5V tap is the green wire on the alkaline battery pack.
It is used as a logical signal to inhibit charging.

Re: Your comment on road construction. You must have been in PA. We now live
in Southern Maryland and used to liven in NJ but we have friends and family
in PA and often travel through it. Every time we go there, we curse the PA
road department. It seems they like to block off 20 miles of road for
construction even though they are only actually working on 1 mile of it.
Sometimes they have so many roads blocked that it is difficult to find a
detour. What can I tell you, write to the PA road department :-)

As far as traffic around NYC at 8:00 PM on Sunday night. Well, if you lived
there, you would certainly want out for the weekend to enjoy some space and
fresh air. Assuming that most people need to return for work on Monday
morning they are on the road Sunday night. Welcome to NYC with 8 million
residents crowded into a few square miles. Boy, Southern Maryland is a great
place to live :-)

First, my ATX finally came from WiMo (purchased at Dayton), right

lotsa room for wire, batteries, & pencils) & off we went. Got to
Valley Forge & went for a walk. Threw the ATX on the BNC connector,
listened a bit, walked, listened a bit more, made a couple calls &
SWR is throught the roof (yes, I had a counterpoise attached).
Realize that now I can't hear anything. Take the ATX off & whaddaya

say, I am NOT a happy camper. Haven't had time yet to contact WiMo
for a replacement....

Now, a question for Pres & the other East-Coasters on the list:
What in the @#$^%#@ is going on? Did you guys decide to rebuild
EVERY road east of the Pennsylvania - Ohio border all at once? And
what is up with traffic at 8:30PM local on a Sunday night through

the air until much later than planned, and only for a very short time
on two evenings rather than every night. Didn't get any DX.

Re: Fw: SSB Filter - Help!

 

Hi Don,

We have found that the SSB filter does give the 817 more kick in the
SSB mode. On both RX and TX, speech is more distinct and the average
RF power increases about 2 dB. This is both by measurement and on-
the-air comments for a number of stations now. It is interesting to
note that a number of positive comments on the 817 audio quality with
the stock filter have been received; however, when I flip in the SSB
filter, the reports are that the audio quality is even better. I
agree that the RX inprovement is best experienced with a good
external speaker.

There is something wrong. First, be sure the filter is installed
correctly. When installed, you should be able to read the lable on
the filter (some folks have tried to put it in upside down). Be
sure
the 4 pins go to the 4 sockets. When the filter is placed in and
out
using menu #38, you should hear only a slight change in audio (more
highs and more lows with the new filter). With the filter, noise
sounds more like white noise. You will hear the difference more
with
a good external speaker. What you are experiencing is wrong. If
the
above doesn't fix it, likely you have a bad filter. But then ....

Dear Don,nice report!

I wonder if you could specify your setting figures ie:

tx hfmid 102
txhfhigh 78
I think you know what i mean,it would give others and myself some idea
what we can expect if we compare your values with ours.
From memory i think the max. value is 124 or so.

I have mine aligned somewhat like yours but found the current
consumption on 2 and 70 a bit high to align for the full 5 watts,so i
left them a bit lower,figured no-one could tell the difference anyway!


Hows that for a mission? max

How do you enter the alignment menu?

With the FT-817 turned OFF, press the A, B, and C keys at the same
