I am trying to get out of connector business, they are a Royal Pain,
but I will continue until a commercial source is found. There are 2
options to rolling your own: Barry's One Plug solution is briallant,

All of the above need a rapid charger to keep packs charged, internal
charger is slow and vague on proper charge. Maha's new C777 Plus is
great unless you want to charge from 12V source, car etc, will only
do 4.8V from 12V source. I have mentioned before I use a Simprop
charger from Germany. They are also avaolable under FMA lable, same
charger. I am polling group to see if there is interest in mass
purchase. I will buy 50 FMA chargers and try and sell for around
$100, list $130. This is a very robust charger typical German
quality. It does cycling and charging with display of capacity, and
also charges 12V Lead, SLA and Gel batteries. How many of you would
be interested. The more interest the better price I can get. I have
small R/C supply business and can purchase large quanity.
See
look under battery chargers.

I gather that the one you're talking about for a group buy is the one
labeled FC700? That would be good, and I'm interested.

Looking at the other items on that page is interesting also. It looks
as if the one labeled MFC100 would be a good small charger for the
W4RT One Plug battery. Since you seem to be knowledgeable about these
things, can you comment on that?

I have been using a small Radio Shack 13.8 VDC 3A regulated switching

wanted to operate. It is catalog number 22-503 at $49.99.

Are you using an outside antenna? My RS supply like this is a real noise
generator. I'd bet the output looks like a comb on an o-scope! Can't use
it with 817 mounted antenna at all.

Do to not camping or hiking much, I'm selling or trading my setup. I
have a FT-817 with RS 1600mah battery pack, LDG Z11 tuner, W&S ATX
Walkabout, CT-26 mod-to-8pin mic connector w/headset. I have
box/manual for the 817 and Z11. Also a Diamond GZV-4000 40amp PS. All
equipment in great shape. I perfer trading for a IC-746/FT-847 or?,
or $1000 for all plus help on the shipping if it ends that way. If
within 150 miles of Detroit I will throw in a 7amp gelcel w/charger.
Email me direct if interested (wa8vbx@...), and I will not
seperate.

yes... I have the same problem.... but mine seems to work in cw when the ssb filter selection is set on (just the opposite). Also noticed that the number on the box is exact but the number on the collins filter is a little different?

Subject: [FT817] CW Filter / IRC 500 hz installation
Date: Mon, 04 Jun 2001 03:47:19 -0000

Hello FT817 owners,
I bought my FT817 at Dayton and finally got it on the air yesterday
(6/2). Today I went to install the 500hz IRC CW filter which I also
bought at Dayton but it doesn't seem to be working. Yes, I changed
menu item 38 to CW. Both the CW and OFF positions sound the same.
When putting the filter menu into the SSB position it sounds filtered
but it sounds like the CW is partially getting cut off. On SSB the
signals are unintelligible with the filter set to ON (SSB that is).
Again the SSB signals sounds the same with the filter in the CW and
OFF positions. So it sounds like the filter may be working but only
when menu item 38 is set to SSB, however, it doesn't sound like any
500 hz CW filter I have ever heard.

I'll be calling IRC tomorrow and I am sure they will either have any
answer or will ship a new one because they have always given great
service and stood behind their products.

I am just wondering if anyone else experienced this though ????????

Dave,

Something is wrong here. If you have a CW filter, Menu #38 should be
set to CW. You should hear no change in sound. If you try to turn
on NAR (row 7, C-key) while in the say USB or LSB, you should hear a
double beep. If you change modes to CW or CWR, NAR should beep once
and the indicator show with the sound changing noticably.

If you have done exactly this and it not work, then I would be in
interested in hearing more.

Yes, there are definitely computers without serial ports. See

<> for an
example.

Just because a computer doesn't have a serial port doesn't mean that it
can't talk serial, that's what USB serial adapters are for. As for other
devices that you would use to talk to the radio, well, a lot of them are
gaining USB connections.

USB means that you can hook many radios to the same computer.
USB means significantly higher data transfer rates.
USB means that you can actually send the audio to the computer for
processing.
USB means a smaller connector on the radio.
USB can mean LESS noise since the wiring is much better shielded.
USB allows for Plug and Play detection.

And saying that USB "USB is harder to deal with programmatically
(libraries, header files, etc.)" is baloney, because you have to use the
same to work with serial ports. As long as the operating system
abstracts the physical ports, they are about the same to work with,
except that you can get a lot more functionality out of USB.

As to radios needing high bit rate interfaces, try keeping a display
in-sync when you are spinning the knob on a VFO. Even channel scan rates
on some radios can pressure a 38.4kbps link.

Can radios use USB to their advantage?

A mobile radio with remote head could talk to the trunk with USB,
wouldn't it be nice to choose the remote head that fit your installation
and the trunk unit that fit your requirements?

An HF radio could have an accessory USB port that allowed you to plug in
whatever DSP device that you want. USB 2.0 (or firewire) could even
allow you to plug in an IF DSP!

A TNC that had one connection to the radio. Audio and Data would both be
carried over the USB cable and then Data transferred to the PC from the
radio->PC connection.

Separate Receivers and Transceivers could be synchronized easily.

Put all of this together and you can get some pretty impressive
configurations at a pretty small cost. It's actually very comparable to
the cost of the RS-232 level converter and connector!

But hey, why not just implement a RS-232 level converter with tubes?


Ed Woodrick

yes, the mod allows for coax or long wire feed.......works like a dream.
all for 29 bucks......takes a couple of hours to build.....good luck,

If you are interested in more information about how the CAT interface
operates, I might suggest visiting my web site at:



There, you'll find a page that has more information on the CAT
interfacing that you might have ever expected to find - including a
number of "undocumented" commands.

While I have not done very much to determine the precise format of
the
cloning process' data stream, I am coming to the conclusion that
what
I *have* found makes the use of the CLONE mode with a computer
(rather
than another radio) *irrelevant*.

There are a few pieces of information yet to be discerned, but at the
very least, I believe that there is enough information already
present
to copy the radio's configuration (including the factory "soft
calibration") or just the memories - or VFO settings - or any
combination of the above. From what I can tell, there is also enough
information to be able to write a program that will properly
manipulate the radio's memories.

I believe that I have (pretty much...) all the information required to
*exactly* duplicate the front panel display and its submenus via the
serial interface.

I must inject a word of warning: Some of these commands can, if
carelessly executed, can result in an '817 that either needs to be
completely re-(soft)aligned, or sent back to the factory - depending
upon your skill and access to a service manual and test equipment!
You have been warned!

I'm still in the "discovery" phase of some of these things - and I'd
appreciate any additions/corrections to what might be posted.

Bill,

Perhaps there's still a chance for this to be done right: a little
8051/PIC/6805 could translate PC keyboard commands to ASCII serial
(if no menus were in the way) and then we'd have a complete solution.

The "complete solution" is already available thanks to the hard work of
Graeme Zimmer, VK3GJZ. Have a look at:



Requires some soldering though...

Unlike the CW filter, the SSB filter is always on once to set function 38.
The NAR has no effect on it.

Maha has battery packs with proper connector. I believe there may be

I also have ordered a large quanity of Deans connectors, 2 pole, and
4 pole. Great replacement for wimpy stock connector and you can make
them up without my help. I will post price and picts after receiving
invoice for purchase. BTW they make great all purpose connectors also.

Serial ports! Blech. It's always the wrong type, wrong speed, wrong
format.

What are the alternatives?

USB is pretty neat and is being put everywhere
Firewire is faster and coming on motherboards
IRDA is growing by leaps and bounds and is rf quiet
Bluetooth is growing but noisy RF wise
Wireless Ethernet is $12.00 in hardware and pretty quiet
Hardwired Ethernet is $15.00 in hardware and quiet if precautions are
followed.

Folks...

Good news...

AOR (the scanner people who also make spectrum displays and DDS VFOs
for Collins gear) have a nifty new widget on the market: the TDR370
"Multimedia Terminal" that does PSK31, RTTY, (no CW) etc. and offers
audio DSP filtering. Built-in LCD display.

See

This device only requires some computing device to run a dumb
terminal program, meaning that a Palm device, which really doesn't
have enough MIPS for PSK31, can be used as the "user interface".

In many ways, though, this is like many other Japanese products out
there that show their designers are clever but a bit "unclear on the
concept": the TDR370 can *read* PSK31, RTTY, etc and display it on
its LCD - grrrrreat! But to *send* PSK31 one needs to connect a
external computing box running a terminal program of some sort. It
would've been tricky-nifty for them to put a PC keyboard port on this
box so it was a standalone unit, no other engine (PC, PalmPilot,
etc.) necessary.

Perhaps there's still a chance for this to be done right: a little
8051/PIC/6805 could translate PC keyboard commands to ASCII serial
(if no menus were in the way) and then we'd have a complete solution.

Folks...

Just had to add this as reading the comment (appended below) drove
me outta lurk mode... No, no, no, no. Please, O Lord, no! No USB on
radios. Keep it plain serial. Put a level converter in the radio
(MAX232, etc.) - or make room for it as an "internal optional
accessory" so that a "lumpy" (i.e., anaconda swallowing a pig) cable
isn't needed.

The advantage of a serial interface is that *any* computing engine
(even microcontrollers) has a serial port - plus or minus a level
converter. If a PC does not have a serial port [I find that hard to
believe; maybe the connector just wasn't brought out from the PCB,
but it'd be a chipset feature] one can be added on the PCMCIA, PCI or
even as an adapter on the USB bus (with appropriate driver). Serial
comms are easy to use, and it's easy to write very generic portable
programs for it.

Not everyone wants a true PC connected to their radio. And USB is
harder to deal with programatically (libraries, header files, etc.)
and it's going to be very RF noisy, esp if other devices are sharing
the bus on a hub. Radios just don't need high-bit-rate interfaces -
9600 or 38400bps serial is just fine.

Off my soapbox...

I'm surprised that so many people find this confusing. Just like any other
transceiver, you have the option to turn your narrow filter on or off (use
it or not as conditions dictate). Installing a filter does not turn it on,
it just makes it available. Use of the, "nar", mode is described on page

14

under, "Front Panel Controls and Switches".

Kind of clarifies THAT issue <G>

via Menu 38. NAR does nothing. I have both filters (but not in the
rig at the same time regrettably). The SSB filter is a 10-pole
Collins mechanical filter and is very nice. It is very flat over the
passband unlike the stock ceramic filter. Don't expect dramatic
changes like you observe with the CW filter. The SSB filter
effectively boosts the lows and highs (the stock filter rolls off the
highs and lows) and cuts off the very lows and highs that the stock
filter passes. To really appreciate the filter, I found that using
the SP-8 speaker makes a "big" difference. Although I have not had
time to get a audio review by the "178" group, initial reports are
that the audio is clearer, sounds some better, etc. Another result
of the flat passband it that the output is more constant in the PSK
mode as you move about the passband.

Sounds like you are the first one to really say the SSB filter is worth
anything. Maybe all of us ASSUMED since the specs were so close that the
reality would be ho-hum

You know, it seems so open inside the rig in that area ( from memory )...do
you think it would be possible to cram 2 in and somehow switch them?

I imagine you may have one-of-each in your 2 FT-817s?

I just picked up some additional Eagle Creek cases yesterday. Their
padded cases seem to be pretty good matches for the FT-817. There's a
little extra room around the sides for accessories, but I'll probably
just get another one for all of my accessories. The quarter sized case
is the one that's slightly bigger than the FT-817. The half sized case
is big enough for just about everything that you need, especially the
double sided one.

Best part is that the cases range from $10 to $20 and seem to be
extremely well made and have a lifetime guarantee.

Ed

I got my FT817 at Dayton and finally put it on the air yesterday
(6/2). Anyway, the rig sitting flat against a table just doesn't
work for me.....too hard to see the display and get at the buttons.

I was at ACE Hardware today and saw a 4 inch paint roller with a
matching size tray. If you turn the tray over, cut off the back half
plus remove the bubble or hump in the back you wind up with a nice
black, heavy vinyl, riser stand for the FT817. It is about 1.25
inches in the back and 1.75 inches in the front. The width is
perfect at about 5.25 inches where the rig sits and 6 inches at the
base where it meets the desk. I finshed off the cut edges with my
dremel tool and it looks pretty good but I think I will spray mine
with black enamel. The open tray cavity under the FT817 fits the
neat little yellow FT817 book from VE3AYR or Palm Paddles, etc.

Also, if you turn the finished tray over the 817 fits right inside of
it. This will be handy for carrying both inside of another bag or
pouch. I will use the Yaesu plastic bag or a bubble wrap bag on the
817 first though. The tray would add some protection for the rig
while traveling.

If interested the tray roller I purchased from ACE Hardware is called
the Speed Roller kit and has a UPC label code of 44359 00500. I'm
sure most paint trays for 4 in. rollers would be very similar.

Just thought I'd share for those interested.

First, WELCOME!

And thanks for the idea. If you have a digital camera ( doesn't everyone? )
please post a picture to the files section... maybe the carry case ideas
section?
