Over 200 members! Cool...

Pretty good considering the radio hasn't been released yet in the US.
Bet that number will really climb once the radio is out in the US and
the rest of the world.

Yaesu FL-110 and Kenwood TL-120 both should work reasonably
well. They were designed for the JA 10 watt era rigs but
the FT-817 should drive either to close to full output
(and leave a bit of headroom.)

Subject: [FT817] Amp for FT-817?
Date: Fri, 27 Oct 2000 19:51:20 -0400

Not trying to dis QRP, but if I wanted to run an amp with this rig down in
the HF frequencies, does anyone have any idea what we'd run? A CB amp was
suggested to me, but I can't find any that are less than around 150A...was
thinking more like 50A.

Double hearsay, from another list...anyone know anything about this?

Oh... and by the way, I just read a report that one of the early FT-
817 units in use by a ham smoked and nearly burst into flames due to
a shorted bifilar DC input choke (no fuse!).

Hello Fellow QRP'ers

Just a new member checking in. This FT817 does look like an interesting rig.
Being a QRP rig, I imagine most U.S. users would be operating CW with it.
This brings me to ask, does anyone know more about the selectivity of the
receiver? If there are provisions for filters and are they the standard
yeasu filters? Last question will this rig drive my Henry K2
linear????????? Just Kiddin!!

Regards
KE7MU Brad

Hi had a bit of time to have a bit more of a look at the cct.
1) whats the 2m intermod like. It looks like it would be worse then the
VX-5. as there is no special 2m band pass filter. Either that or 2m is
excellent but out of bad RX completely shot!
2) looks like NiCd pack is detected automatically and trickle charged at
about 12mA or if you use your own cells you can manually select charge from
the menu (or I supose fast charge the NiCd pack) at 120mA.
3) looks like the unit is Linear or antenna tuner compatible as the
CAT/LINEAR plug on the back has a line that goes low on TX, a TX tune line
and Band Data as well as 13.8 current limitted (10 Ohm res) and the
programing serial lines TX/RX.
4) there is no data line from the mike so they are using a generic DTMF
chip in the Mic to generate DTMF tones. With only the 3 user programable
buttons available for controlling the radio. That is unless of course the
radio decodes the DTMF tones to operate certain functions which is possible
I supose.

Well hope that helps if anybody is interested.
Cheers
Eric.

Folks...

Took a look late last nite at the various schematics uploaded to the
files section - specifically, the controller. [It's in the file
FRONTschematic.pdf, IIRC.]

The CPU here is a high-integration "all-in-one" controller that has
quite a nice little CPU inside - besides ROM, RAM and peripherals.
It's part of Hitachi's H8S (actually, H8S/2000) series. The part # is
HD64F2345FA, meaning it's a -2345 variant architecture, with flash
memory ("F") in a 100-pin ("A") SMD package. The Hitachi website is:



Drill down to find the .PDF file for this controller. I did a quick
perusal (I've seen H8 stuff before; Yaesu seems to like it; my VX5
and VX150 have smaller 8bit H8s on 'em) but this is a quick,
approximate rundown...

This very capable 16/32 bit CPU can be clocked up to 20MHz. It has
128KB flash ROM, 4KB RAM, 6 x 16bit timers, 2 x 8 bit timers, 8
channels of 10bit ADC, 2ch 8bit DAC, something akin to a DMA
controller, and 2 multimode serial channels. Various memory ranges
can be configured to be of differing bus widths. There's some
smartcard support features too. Not all of these features are used
on the FT817 - for example, no external memory-mapped peripherals are
used. Other chips (PLL, DDS, etc.) are controlled via fast serial
data transfers - even "user memory" for settings, freq memories, etc.
is stored in an external serial EEPROM (24C64).

A quick read indicates this CPU apparently has a small fixed factory
boot ROM space so that its (empty) flash can be programmed via a
serial port. It can also be programmed/verified as a freestanding
chip on a chip writer (it's a 27F101). I note *no* ROM code
protection features [other than some anti-go-wild stuff, there's no
code-lock or encryption]. Thus it appears the code can be somehow
dumped and analyzed & tweaked, worst case requiring de/re-soldering
of the chip. I did NOT immediately see a graceful way for code to be
dumped out of the flash ROM to the outside world while still soldered
to the controller board. There *may* be some way the code can be
dumped from this chip without desoldering it and reading it on a
burner; I will have to look into it. [It is likely this code is
mostly written using compiled C. Speaking from quite a bit of
reverse-engineering experience, reading disassembled C is sometimes
much harder than reading human-written assembly code; we humans think
somewhat alike, and not much like a compiler ;-).]

There's probably quite a few "hidden" features, modes, etc. here we
should find out about and that the more brave amongst us may wanna
tweak. After all, I am indeed a charter member of the International
Association of Warranty Violators :-P

Doesen't SOUND as good? How about won't work at all. Not only do the
electret elements present an impedence mismatch, but they also require a
bias voltage which Yaesu allmode rigs do not supply.

This Japanese page has some good internal pictures of the rig.
If this info already posted here apologies for spam.

I have a few questions about the new FT-817.

1. What is the specification for frequency stability for the standard
reference oscillator?

2. Is the optional high stability oscillator a "plug-in" change or does it
involve screwing around doing some soldering?

3. I saw one large slot for a plug in filter. Is there only an option for
one additional filter or two, one for SSB and anther for CW?

4. Does it look like there maybe room to install one of the Inrad high
performance crystal filters inside?

5. Is there a line on one of the jacks on the back which can be used for an
external amplifier keying line?

6. Is there a headset/boom-mic which can be used with this rig?

7. Can NiMH batteries be used in place of the NiCAD battery pack?

8. Any known TX/RX mods? If so does it screw up any of the automatic options
such as auto repeater shift etc. like on the 847?

9. Is there a "hidden" alignment menu, like the 847 has, which lets TX
power, RX gain etc. settings be changed?

Will any of the existing ADMS programing software work with the
FT-817?

Hi all,
Hope this hasn't been covered before..
Anyone know if it will work with any of the autotuners, ie, ATAS-100 or
FC-20?
Thanks

Hi. Does anyone know about vinyl or ( preferred ) tough leather cases? I
absolutely insist on all my portables being sheathed. They had a terrific
thick hard leather case for the original FT-x90 series ( 290, 790, 690 ).

Hi Bill,

I went to the Universal Radio website and it states the MH-36E8J
is the optional DTMF mic. Don't know if this is the definite
answer. Whether or not your MH-36 that came with the FT-1500 will
fit/work is a question for Yaesu or the curious (like myself). I
hope it would. Check it out at:



The options and prices are listed at the bottom of the page...
