[Repeater-Builder] Astron RS-35M pass transistor Socket

2008-02-05 Thread Vince Staffo
My Astron RS-35M Power Supply has developed a problem with one of the
sockets used for the TO-3 Pass Transistors. The Astron supplied socket 
does not look like it is very good quality. Does anyone know of a 
better replacemnt socket that I could use? If so please provide part 
number and where to order if possible.

Thank You,

Hi Vince, cannot help you with the socket - maybe Newark or Mouser, or 
such.  I have seen folks actually solder to the leads on the pass 
transistor if all else fails.  73, Steve NU5D

[Repeater-Builder] Unknown board

Hi all, I posted 4 pics in the photo section of a board I got in a lot
of radio equipment that I purchased.  I have no idea what it is or
what its used for.  All I know is the 2 connectors on the left, the
top says TX and the bottom says RX, and the 3 pots on the right say
Hi, Lo and VCO.  I got 2 of them exactly alike, any help would be
appreciated.  If you have any more questions or want more pics let me
know. Thanks.



[Repeater-Builder] ARRL/TAPR Digital Communications Conference in Chicago Dates Announced

2008-02-05 Thread Mark Thompson
Dates for ARRL/TAPR Digital Communications Conference in Chicago Announced (Feb 
4, 2008) -- 

The Tucson Amateur Packet Radio Corporation (TAPR) has announced that the 2008 
ARRL/TAPR Digital Communications Conference will take place September 26-28 at 
the Holiday Inn Hotel in Elk Grove Village, Illinois, a suburb of Chicago, near 
O'Hare airport. 

The conference is an international forum for radio amateurs to meet, publish 
their work and present new ideas and techniques. Presenters and attendees will 
have the opportunity to exchange ideas and learn about recent hardware and 
software advances, theories, experimental results and practical applications. 
Forums will feature the latest developments in Amateur Radio digital 
communications, as well as demonstrations of emerging digital technology.

[Repeater-Builder] Community Repeater War Stories (the saga continues)

In an ideal world... in the real world everyone knows who the

That would be a number greater than 1.

Should be a type of feature or function programmed into both 
the radio and some of the better repeater tone panels. Normally 
never turned on at the user-radio end unless the radio shop is 
really paying attention at the time of (the radio) programming.

... or simply jamming the other user right off the frequency 
with a high powered radio.

Until the user wraps a bit of wire or paper clip around the mic 
grounding hang-up post/pin/connection.

Annoyed = "have a brain anyurism" or throw (at speeds greater than 
50mph) the mic against the wall.

Even using the LTR Trunking format with a single repeater is a 
much desired operation.

And for older legacy radio equipment without the capacity to 
operate with the trunking system format. Trunking radios cost 
a slight bit more money per radio versus some of the really low 
cost units we see flooding the market. 

Trunking works well and solves a number of long time pesky problems. 
There are a number of trunking radio data formats available but the 
most popular consumer public use format is the "LTR Trunking" 
format.

The XR2206 and 2211 chips are modulator/demodulator chips...  I used them to

My guess would be some sort of modem.

Re: [Repeater-Builder] Astron RS-35M pass transistor Socket

2008-02-05 Thread Dexter McIntyre W4DEX
The most reliable solution is to just break those flimsy socket pins off 
and solder the wires directly to the transistor leads.  I've had several 
supplies fail because of these type sockets.  I suspect the transistor 
may have failed because of the heat produced by the small contact area 
of the socket pins.  Never had a transistor failure after soldering.

Re: [Repeater-Builder] Re: Low-band MaraTrac Squelch Pots

2008-02-05 Thread Bob M.
After soldering a wire from point-A to point-B, I
thought I fixed the problem, but it persisted.

I scoped all the signals on J21 and found that the one
on pin 8 was going away. The connection from the audio
board, at the back of the pin-side of the connector,
to the logic board, and even the interconnect board,
was going open when the squelch failed. No detected
audio, no squelch operation.

The socket at pin 8 of J21 seems to be defective. It's
not gripping the pin coming in from the audio board. I
can put a resistor lead into any of the other holes
and feel the contact gripping the lead, but on pin 8
it just wobbles around.

I could replace the connector IF I had a part number
and IF Motorola still had one. It's an 18-pin female
dual row, right-angle, 0.100 inch type. I didn't find
one on Mouser, but did find a 2mm connector of the
right style.

The alternative is to solder a wire from the
interconnect board directly to the pin 8 of J21 on the
audio board. This would bypass the connector and
insure it never fails again, but removing the board
would require unsoldering the wire.

I didn't expect this kind of failure. I have a feeling
it was a defective part installed at the factory, and
if the radio never had the need for carrier squelch,
no one ever cared about it. Also, the connection would
be good once in a while, so it might have worked when
it left the factory and just decided to fail later in
life.
