CROSSBAND-REPEATER-FUNKTION
Wenn die Taste "RPT" = 6 waehrend
des Einschaltens gedrueckt wird, ist die Repeater-Funktion geschaltet, d.h.
Signale aus dem MAIN-BAND werden in das SUB-BAND und umgekehrt uebertragen. (2-m
nach 70-cm und umgekehrt). Hierbei wird die Ausgangsleistung automatisch auf LOW
gesetzt. Die CTCSS-Funktion wird eingeschaltet (kann nachtraeglich, wie im
Handbuch beschrieben, geaendert werden).
Kommen Signale im "SUB-BAND" an,
werden sie im "MAIN-BAND" ausgestrahlt und umgekehrt. Es sind hierbei die
Bestimmungen ueber REPEATER zu beachten.
Nach dem Ausschalten des
Geraetes ist die "Repeater-Funktion" geloescht und muesste wieder neu gestartet
werden.
Wird beim Einschalten des Geraetes die Taste "REV" (CLOCK)
gedrueckt gehalten, so werden nur alle empfangenen Sendungen auf dem "SUB-BAND"
in das "MAIN-BAND" umgesetzt.
Die CTCSS-Funktion und die
LOW-POWER-Steuerung koennen hier selbstverstaendlich auch nachtraeglich
geaendert werden.
IN JEDEM FALL wird beim Ausschalten des Geraetes die
CROSSBAND-REPEATER-Funktion geloescht. Sie muss also immer wieder NEU in der
oben angefuehrten Weise aufgerufen werden.

Umbau der Yaesu FT-530 für Packet Radio Betrieb mit 9600
Baud
Hallo 9k6-Freaks und sonstige OMs die es
interessiert...
Heute ist es mir gelungen, nach langem Studium des
Schaltplanes meinen TRX für 9k6 umzubauen. Um anderen die Mühe zu ersparen,
beschreibe ich es...
Man nimmt den Batteriekasten, Akku oder die
Abdeckplatte ab und schraubt die 4 Schrauben, die die Bodenplatte halten heraus
und nimmt die Platte mit den Kontakten vorsichtig heraus (ACHTUNG
Folienkabel!!!).
Es wird eine Platine sichtbar, vielmehr deren
Rückseite.
Man sieht dort 4 Reihen mit Lötpunkten, die jeweils von rechts
nach links gehen. Hier sind die Anschlüsse zu machen, jetzt nur keine
Panik.
Jetzt sind Mathematiker gefragt, es gehts ums zählen der Pins !
(HI)
Schlachtplan (Handy von unten gesehen):
+-----------------------+
| O |
| O ........... +------+|
| O ........... | ||
| O 15 11 +------+|
| ...|.|..... |
| ........... |
+-----------------------+
Die Punkte sollen die Pinreihen darstellen. Zwei Pins sind durch Striche
ersetzt
und die Zahlen 11 und 15 drangeschrieben. Das sind unsere
Kandidaten:
An Pin 11 wird das Empfangssignal fürs TNC abgegriffen und an
Pin 15 wird die Sende-NF eingespeist.
Anschlußplan für Masse und PTT:
+--------+
| |----=---
| |----=---/
+--------+ | |
Masse +---2kÛ---PTT
Der Masseanschluß und die Verbindung der PTT geschieht über die
2,5mm-Klinken- buchse an der Oberseite des TRX (eigentlich für externes Mic
gedacht). Die PTT wird über einen 2 Kiloohm-Widerstand an die Spitze des
Klinkensteckers gelötet. Die Masse wie immer an den anderen Anschluß des
Steckers.
Wie man die Kabelanschlüsse der Unterseite aus dem Gerät
herausführt, weiß ich nicht (liegt bei mir noch offen rum,HI), aber vielleicht
hat ja einer 'ne GUTE Idee. Wäre nett wenn ich von der "GUTEN" Idee etwas
erfahren würde. Es würde mich sehr freuen!!!!
Ich übernehme KEINERLEI
Haftung für entstehende Schäden, aber ich stehe für weitere Auskünfte oder
Nachfragen gern bereit!

19-07-1998 Expanded frequency range up to
950 MHz
Hi, this message is for those who have done the pad 13
mod to the FT-530.
This sequence permits putting a 500 mhz or higher freq in
a memory channel.
Example:
To enter a freq of 506.8375 make sure you
are in the uhf band.
- Press 'FM'
- Press 'STEP'
- Rotate dial to select 12.5 step
- Press 'STEP'
- Enter 800.00
- Press 'FM'
- Press '/' MHz
799.00 Will show on the display. Turn the dial (top
right-rubber duck on left) counter clockwise. The display will decrease in 1
MHz steps. If you pause for more than 2 seconds it will revert to a decrease
of KHz steps. To get back to MHz steps just press 'FM' then press '/' MHz.
Continue till 507.00 shows on the display. Pause for 3sec. Turn dial counter
clockwise and the freq will decrease in KHz steps. Turn till 506.8375 shows on
the display.
- Press 'FM' for 3 sec. The memory channel number will be flashing.
- Turn dial to select memory channel
- When channel is selected press 'FM'. The freq is entered in that memory
ch. back to MHz steps just press 'FM' then press '/' MHz. Continue till 507.00
shows on the display. Pause for 3sec. Turn dial counter clockwise and the freq
will decrease in KHz steps. Turn till 506.8375 shows on the display.
If you go pass the freq you cannot turn the dial clockwise to go up
freq. If you do so the display reverts to 300 MHz and you must start at
#5.
Helpful hint example: 506.8375 is now in memory channel 5. Press 'MR'
and select channel 5. 506.8375 Is now on the display. Pressing 'MR' again will
normally let you (>>>> shows under channel number) tune up or down
in freq. Now on these over 500 MHz freq you can only tune down (counter
clockwise). Tune up (clockwise) and display go to 300.xx MHz. Press 'MR' and the
correct memory channel freq is displayed again. The PLL on my unit will not lock
above 507.6 MHz on another FT-530 it will lock over 508.4. Pressing the push to
talk will display an error on the display and if the PLL will not hold the freq
display will flash. 800-950 is the upper range of my unit and receives fb. Any
other mods or key inputs please send to WA3YZL @WB3JOE. PA.USA 73 Paul

19-07-1998 Yaesu FT530 AM
receive
Hello,
There seems to be a difference in the way
the AM receive on my new Yaesu FT530 works compared to that of the instruction
booklet.
The instruction booklet says that if you enable AM receive (key
sequence: FM, Set/0, FM, PRI/VFO) that it affects "the entire VHF receiver". Yet
I am finding that I seem to be able to store the mode along with the frequency
in the memory channels and then scan a mix of AM and FM frequencies. It also
seems that one can set both VHF VFO's to one of AM or FM.
I am curious if
anyone can add to the explanation on how AM receive works on this fine radio? I
would guess the design engineers made an enhancement to the firmware after the
documentation was completed...

You
can store the "MODE" in memory.
Setting the unit to AM can be done on either
VFO.
Setting the unit to AM will preclude you from receiving 2M FM.
As
for how it's done... from what I heard (I never bothered to check) they run the
signal through the S-Meter diode to demodulate AM.

19-07-1998 Extended
range for FT-530 New models
Here is the summary of a mod that
I've put together from talking to people on the phone, radio, and email for the
Yaesu FT-530. It is a very simple mod and it allows extended RX &
TX.
This mod only applies to the newer models of the 530. I don't know what
serial number implies the newer model, but my 530's serial number begins with
4J381xxx and was purchased in June 1995.
- take off the battery pack from the bottom of the radio.
- unscrew the four screws on the bottom to release the bottom plate.
- after you open the plate, you'll see a green wire on the right side of the
radio (if you hold it with the front panel on top).
- simply cut this green wire and use some electrical tape to prevent it from
touching other parts of the radio.
- replace the bottom plate and screw it back in.
- attach the battery
- hold both the up & down Mhz arrow buttons and press the power button
at the same time. this will enable to the mod. It is like a toggle, if you do
it again, it will disable to the mod.
- Now you should have rx 110-180, 300-500, 800-950, and tx 130-180, 400-480.
Note:
this mod will reset your radio and all memories will be
erased.
Here is a second mod you can do to get more rx.
- On the 70cm band, program your radio's lower (L) and upper (U) memory
limits to 300 and 950.
- Turn to the Lower memory channel.
- Press MR once and you should see a four tiny little arrows right below the
channel number.
- Once you see these little arrows, you can enter any frequency from 300-950
Mhz directly on the keypad.
You can also store these new rx
frequencies in memory if you like. Note: Although you can enter 800-950 Mhz into
the radio, I have not heard anything in this range. It is rumored that the
components to receive on this band is no longer made in the
FT530.
Disclaimer: Perform these mods at your own risk. They are not
guaranteed to work on your radio. And remember not to transmit out of
band!!!

18-12-1998 FT-530 Extended RX/TX Mod
Update
March 19, 1995
By KA0RNY
Hi
everybody.
This update is for those of you who have been unsuccessful
with the extended RX/TX mod on the Yaesu FT-530. I tried unsuccessfully twice to
perform the mod previously. I decided to give it a try again using a tip from a
Yaesu Service Technician. The Tech I talked to said the mod should work, but
that the reset sequence might need to be performed twice. Viola! It
worked!
Before you dig into your radio be sure you have a good copy of
the mod sheet. The one I'd recommend is ft530.mod which can be gotten off the
Internet via FTP at oak.oakland.edu in the pub/hamradio/mods/yaesu directory.
There are several other mod files for the FT-530 as well as other radios. If you
don't have Internet access you may retrieve this file via REQDIR in the MODS
directory on my home BBS, KB5TBQ.#NCOK.OK.USA.NOAM or any other packet BBS that
keeps mod files.
Now that you have the mod info, perform it as
instructed. If you have a very new FT-530, then it's possible that all you'll
need to do is remove the four screws holding the battery mounting plate to the
radio. Looking toward the back of the radio on the opposite side of the latch
you might see a small green wire tucked under the white paper insulator. In two
FT-530s here in town that are newer than mine, the wire exists and is all that
needs to be cut for extended RX/TX. The wire ends are soldered to each side of
Pad 13 so no unsoldering is required. For extended RX only with TX limited to
ham bands, the small 0ê surface mount chip resistor, Pad 15, needs to be removed
also. If your rig is an older model, then you'll need to unsolder Pad 13. I had
excellent results using a manual solder sucker to remove the solder bridge. A
good set of eyes or a magnifying glass may need to be employed to be sure that
all the solder bridge is removed. The mod won't work if any contact exists
between each side of Pad 13.
As the mod sheet instructs, be sure that all
power has been removed from the radio, I even pulled the lithium battery (you
did remember to make a list of ALL your programmed memories didn't you?). Slip
the battery back on and power up the radio while holding both arrow buttons
down. Now twist the dial knob counter-clockwise. If the frequency will drop
below 430 MHz, go no further as the mod should be successful. You may want to
press F/M then Down Arrow and tune in 1 MHz steps downward. Check to see that
you can tune to 300 MHz and that it wraps around to 500 MHz. If you twist the
dial knob and you wrap around to 450 MHz, reset the radio again by turning it on
while pressing the arrow buttons.
After you've reset the radio and
activated the extended features, check to be sure that your frequency step size
and repeater shifts are correct. Now you can enjoy reprogramming your radio
again! I haven't found any features that have been disabled by performing the
mod. Automatic Repeater Shift is preserved, unlike the mobile units. Also my rig
tunes in the 900 MHz range which is quite useful to me since I can monitor a 930
MHz data system that I maintain. It also appears to monitor the entire 902 to
928 MHz band which should be a boon to generating interest in the 33 cm band.
All you need to do is punch a frequency from the keypad. From there you can tune
up or down with either the arrow keys or the dial knob. Also, you can store any
of these frequencies in memory, tune or scan them as any other
memories.
I really enjoy the added dimension the extended features give
the FT-530. Being able to use one radio to receive so many different frequencies
makes it a real Handy Talkie.

22-08-1999 Yaesu FT-530, Tune Any Freq.
EASILY Between 110 and 950 inclusive
On a hardware modified for
extended recieve and transmit ft-530, you may, without having the difficulty of
popping out of range when tuning upward, tune absolutely any freqency between
110 and 950 mhz (although mine only locks between 748-950, 520-300,
183-110.
This is a big improvement over entering 800 in a vfo and tuning
down only with the knob.
- Enter 110 in the "L" memmory channel on the UHF side of the rig.
- Enter 950 in the "H" memmory channel on the UHF side of the rig.
- Be sure that neither "L" nor "H" channels are marked as skip channels.
- In memmory mode tune the "H" channel.
- Press MR to get the little adjustment lines ---
- Enter the freq. of your choice, ANY FREQ. BETWEEN 110 AND 950
MHZ.
Note: you can only do this once, if you need to enter
another freq, you must exit and enter memmory mode.
There you go. The
VHF side of the rig tunes over a larger VHF range and same for the UHF side of
the rig. You can use the xfer (9) button to transfer a freq to the VHF side to
the rig will lock (for example tuning 181.000)
Good luck and
enjoy.
