I think MFJ makes an antenna for apartments.  It uses a counterpoise.
Check eham.net for reviews.

Currently Tech class, about to take general test. Call is KM5MFP.

Antenna needs are 2m/70cm but want to get prepared for other bands.

You can try a magnetic loop antenna. I just bought one (ML 40 HP) and am
using it on 20m from inside the house. Spoke to Estonia, poland, italy
etc... from the netherlands using 5 watt, SSB on 20m

This is the one I have:G4TPH - ML 40 HP

Hi

New to the list. Currently have an FT817 and love it! Mostly use hombrew
wire antennas.

When I got started the FT897 was too much and since then, things have
changed.

So am now looking to upgrade. The question is really an FT897 or FT450D
since there is no shortage of 2m/70cm gear here. ;-)

Will search the archives for previous answers. Seems like the familiarity
with the menus and functions on the 817 scales up easily to the 897. And I
do take my 817 portable which should continue post upgrade.

73 and thanks in advance for all the information!

HI,

The Eh antenna, hummm?
See the site PY1AHD...and yahoo video, test about this antenna...
He have Loop magnetic, this antenna is small but is very good.
I used in field operation, is really good. with 5w I covered about 2000km.
I was in beach, long island... Iwas two qso´s in 18 e 14mhz.
See the yahoo and the site and draw your own conclusions ...

All:

I agree the magnetic loop may be a good way to go. Anything that keeps
the entire antenna system outside or as much away from apartment wiring
and devices is going to help get more signal out, minimize noise into
the antenna from the apartment, and limit interference with devices in
the apartment.

As to the EH antenna... Please do some reading on this antenna before
you think about trying one. Here's a Yahoo group with some good
information on the claims made.

http://groups.yahoo.com/group/ehantenna/

Despite the developer's claims, the only way the EH antenna works is by
using feed-line radiation. This is not what you want for an apartment
antenna. If you try to choke off those common-mode currents on the
transmission line the antenna will not work so it's not a good candidate
(for any use IMHO).

If the packaging for being more portable, or other modes on 2m and 440 isn't
desired you'll probably want the FT-450D. More modern IF DSP filtering from
their larger rigs.

I was making the same decision last year and went with the 897 ( The
Kenwood TS-480 was on the short list as well ).   I did not have a 2M or
440 base here and had no 2M or 440 SSB / CW capability - that
was a major factor with the 897 purchase - that and the ability to use
the internal
batteries or power supply - I have a higher expectation of portability
and ruggedness
from the 897D.

I liked the internal antenna tuner on the 450 but from what I read it
was inadequate
for the antennas that I use as it has a very limited range.

The 450 is MUCH easier to do the wideband mod on than the 897 if you want
to open up 60 M 0 but thats one channel, and its not available yet.

Net - after 5 months of very frequent use I am very pleased with the
FT897D.  I use all bands from 160 - 440 and all modes.  ( SSB, CW, AM,
FM, PSK, RTTY, JT65 etc. ) .  It took me a few days  to get used to the
menus .  I also run Ham Radio Deluxe for rig control and that interfaces
well but honestly I do not 'need' HRD to be effective with the radio -
but it does simplify things when I am tweaking settings.

Hello! Regarding the newer dsp technology, I agree.  Also, the 450D has the
built-in tuner, which is a nice bonus, and its bigger display is very nice. 
However, I must add that I spoke with the Yaesu rep at a recent DX convention
and he said that the 897D can come very close to rivaling the 450D's receive
capabilites when the Collins filters are installed.

I have a ground-mounted GAP Challenger here. It’s quiet because it is deaf!
My homebrew 135 ft long OCF dipole with a 6/1 balun  outperforms the Gap in most
cases  on all bands up to 10 meters and most certainly outperforms the GAP as an
NVIS antenna on 80 meters (haven’t used it as an NVIS antenna on 40 and 30
meters).
If you want a good vertical, use a 41 to 43 ft high antenna with lots of radials
and a remote tuner at the base of the antenna. Even then, the antenna won’t be
a good NVIS radiator for local nets.

Cheers, Deme, VE7CRT.

Hi Barry - my 897D also does this occasionally. originally i thought it was RF
due to a loop antenna I was experimenting with - but in recent months I have
used a nice resonant dipole - which is driven through the LDG 897 Plus AT, and
includes a LDG 1:1 balun. So I don't think its RF . . . This morning it reset
again. It loses all memory - fortunately I have the whole damm thing backed up
on FTBasicMMO. Another problem my radio has is its deaf on VHF and UHF - or
almost deaf. I was advised to replace a small diode on the motherboard - but the
supplier was not able to do this due to its small size. I haven't found anyone
else able to do this either - and sending it back to Yaesu isn't an option due
to cost. So it remains a dumb HF set for me! Together with the reset problem I
am now looking for something new! Let me know if you crack this one!

I think it was a loose PL259 connection.

All is fine now.  (Knock on wood).

Hi,
I just fired up the 897 and found it stuck where I last left it. The band
switches and mode switches don't seem to function. It also won't transmit. Any
ideas?  Thanks, Peter K7TRZ

Before resetting the radio, try a few simple things first...

It might be that a CW key or some other plug in accessory (even the Mic) is
holding the radio in transmit mode when turned on. Turn off the radio and then
the power supply. unplug everything but the antenna and power supply from the
radio and turn the power supply and then the radio back on.

If the radio comes up ok then plug in the mic, still OK? then plug accessories
one at a time and see if the radio is OK...

If the problem persists then it could be that the cabling from the inside of the
front panel to the main body is messed up and needs to be reseated... or a radio
reset may be in order.

Personally, I would try other options before resetting the radio....  If the
problem still persists then it may be time to send the radio in for repair.

Hello Fellow hams,

Sorry I'm just lazy looking out the previous mail I just wanted to know
what types of cable do I need to connect to the Ham radio deluxe program,
  is it the CAT cable or the data cable?
I found in the ebay
USB programming CAT cable Yaesu FT-817ND FT-857D FT-897D FT-100D RADIO

The right cable is the cat to din. The best one I have found is from Hro.com
with the programming software. I spent a lot of money buy cables from ebay and
other sites and none of them worked just as the "free" programming software did
not talk to the radio.

I think you need an Antenna Tuner

Shon,

My YL and I use a Chameleon V12 for portable work, it comes with a 9:1 balun
and yes, it does require a tuner. Used it as a base antenna for a couple of
weeks last year while we moved our antennas away from the house as well, have
had excellent results with the Chameleon when attached to 15 ft mast using a 5ft
tripod. We also added two more radials for a total of six. Results not so great
if not that high up and also not great if radials not grounded properly.

The GAP Eagle we use at our QTH does not require a tuner, great antenna for us
for 40 - 10 meters.

Hi, Thanks again everyone for all the help I can't thank you enough. Has anyone
used the CHAMELEON V11 or the CHAMELEON V12? I was looking at those one also but
I think you need an Antenna Tuner

Thanks

I have not used the V11or V12 but I do use the V1 and Hybrid systems and both
are excellent performers.  Yes, the Chameleon antennas do require the use of a
tuner.
   Keep an eye on Chameleon as they are developing base station accessories for
the antennas.
I do not work for them but am a believer.

Now that the rules for the 60m band changes have been formalized, has there been
any word from Yaesu on firmware updates to the FT-897D?  I really have no desire
to wideband my radio and hope they will be able to update it support the changes
to 60m.
