Welcome to the RMR net today, with snow on the way, and the wind up.. again.
I will be using my temp antenna, that is 20 foot at the apex, and hopefully be able to
use relays too.
Drop by, say hi.


Have a great day,

Meeting Saturday

David Bixler <qrp@...>
 

Hello folks:

This is your reminder that the February 4SQRP luncheon gathering will be this upcoming Saturday, the 16th, at the Country Kitchen in downtown Seneca, MO. Lunch will be at 11:00 AM.

There are directions to the Country Kitchen on the 4SQRP web site at: http://www.4sqrp.com/CountryCupboard.html

The WX forecast says that Saturday will be cooler, but no rain or snow predicted. The yellow daffodils are blooming at my QTH so spring is getting close!

This message is being sent to both the old and new email reflectors, so you may get two copies of the message.

Dave,
  I've had a little trouble with my truck.  I replaced what the shop said was a bad battery, but it seems to be still running a little rough.  I think we'll stay near town until I'm convinced that's all it was. 
  We'll try to make it next month.  Say hello to everyone for us!
  Hope to see you soon.

Thanks Scott, sri I missed posting that.
 
The launch crew is planning a 9AM CST launch, wx permitting. A nice day is predicted so I'll begin listening abt 8:30A.

Tks to everybody who replied both on and off list to my T/R Switching query. Overall, it looks like the Magic Box is the way to go. I can experiment and expand from there.

Subject: T/R Switching

As a recent joiner of 4SQRP, I'm looking forward to getting back into building my own stuff. The NS-40 seems to be a popular and well designed rig, and my plan is to use my FT-857 for the RX side. Otherwise, the 857 is my day-to-day rig, and I have to protect it. (For QRP use, I drop the drive down and measure the output on an external wattmeter.)
 
So here's a newbie query from an old time ham (me!) who should know the answer but doesn't: What is everyone else who uses separate TX and RX units doing to mute their RXs when the TXs are doing their thing? A rule of thumb was given me a few days ago that there must be at least 40 dB attenuation to protect the RX front end, but that's also going to depend on what the TX power is to start with.
 
My old Hallicrafters RXs could handle a bit of a pop at QRP levels when I did manual switching. I'm a bit leery however about subjecting the "newfangled" 857 to similar treatment. I never had a Dow key which would've done nicely for the boat anchors, but - assuming I could put my hands on one - would a Dow key with its mechanical relay have fast enough response time to protect the 857's front end?
 
What other alternatives are currently in play?
 
Tks/73,
 
Jim, ND9M / VQ9JC

The launch took place at 9AM CST as planned. The CW beacon is working well I
have it at abt 569 on 14.323.5. The GPS isnt working at this point in the
flight, so there is no tracking available. If it gains a lock tracking will be
availabe on this web page

IHAB Beacon

WA0ITP
 

I'm posting this so you dont spend continue to look for the IHAB9 Beacon on
14.323.

The launch was at 1500z and the beacon worked well until 1553z when it developed
a chirp, then it failed at 1615z.

The ballooon is expected to land near Burlington, IA, but without ground
tracking or the beacon, recovery is doubtful. It is hoped that someone will
find it and call Marshall's phone number to report the discovery.

Thanx for listening. There will be more launches this summer.

I ordered a three-band transmitter-receiver kit from Doug KI6DS that mounts a small printed circuit board to a mother board using a 16-pin right-angled connector strip.  Unfortunately, the board mounting holes are too small for the spade-shaped pins in the connector strip.  I tried drilling out the holes, but succeeded only in displacing a few solder islands.  The Mouser catalogue does not offer any connectors that have round pins.

Short of spending infinite amounts of time filing the spade pins down to a round shape, I would appreciate any suggestions, or sources of round-pin connector strips.

Re: Fw: Mechanical problem

Unfortunately, the hole through cladding connects the top of the board to the bottom of the board, in three cases.
Those in particular are critical to have continuity. The others not so much just from the board to the display board.
The pins in question fit into the holes with a careful and firm effort, providing a modicum of phyisical strength to the
display board, and firmly keeping it in place, without relying entirely on physically weak solder to hold it in place.
  Depending on which holes have been drilled, repairs may be done with no additional damage to the board, by adding
#30 silver coated wire from top to bottom through the holes that require it, and placing the connectors in place, soldering them
very well. BE attentive to the way the connectors must be placed, or it won't fit the case, when completed.
  After the display is in place, an ohmmeter may be a very good friend, to insure connectivity is accomplished.
 
Good Luck,

Have a great day,

Re: Fw: Mechanical problem

I have used an IC mount for an 8 pin chip before and cut it up into 8 different pieces. I soldered the pin end to the board then could mount the desired device into the pins. This is also useful for parts that you may want to be able to exchange in the future for experiments or changing freq. or functions. I end up destroying a few in the process but it is an inexpensive way to do this. Here is an of a part to cut up: http://www.newark.com/multicomp/2227mc-18-03-08-f1/connector-dip-socket-18way-pc-board/dp/98K7083
