Hi Doc,
Go to lnrprecision home page, then "trancievers" then scrool down to "FX-4", that link works and takes you here:
It is on the back burner for now in lieu of the much improved LD-5 due out this year.

Re: RF signal routing through an amplifier

Chuck Carpenter
 

Jim,

In the Topper amplifier that I did, I used an RF activated relay T/R switch to bypass the amplifier in receive mode.

One way is to use a relay or pin-diode switch to
reroute the receive signal when in receive mode.

While looking at various kit web sites, I was curious about RF amplifiers and QRP transceiver applications. As in a transceiver with a watt or less and the option of a little more transmit power is desired.

My specific question: If the input to an rf amplifier is from the antenna output of a transceiver, when in receive mode, how does the received signal make it through the amp inbound to the transceiver?

I can visualize the application when a transmitter/amplifier combination is used with a separate receiver and either a manual or automatic antenna switch routes the signal path, but when the switching is internal to a transceiver, I just can't figure out how the transmitted and received signal can move both directions through the amp.

I'll probably be embarrassed by the answers, but just curious.

Re: Monday Night Checkins

I was having computer issues and didn't find the frequency you used until after the net was over. 

Personally I prefer to keep the net at 7:30 since that gives me time to finish supper, clean off the table, get the kids settled down, etc. before playing radio.

Hi Jeremy,

I was listening at 7.282 or so, but didn't hear much of anything going on. Just
a  weak round table up about 7.287 or so, and something at 7.278 or so.
I didn't tune down any farther than that, as I had missed your last post about a 
lower freq. 

Will be at work next week, so will try again in about 2 weeks.   
I really need to get my "pig remote" hooked up to the KX3 and then I could
try to check in on the android phone app. while on break at work.
One of these days I'll get that running and have some fun from work....

If you need (or want) the capability of Photoshop, but are not a professional in a photo related field, try GIMP - it is a multi-platform photo editor with most all the capabilities of Photoshop.  Open Source and at no cost.

If you already have access to PhotoShop, it is fine for doing simple
jobs like those. But you might not want to go out and buy it unless
you really need it's full (and considerable) functionality. I don't
know if they still offer it as a standalone product you load onto your
computer, but if they do, it's probably still quite a few hundred
dollars. (I remember years ago when it was somewhere in the vicinity
of a thousand dollars.)

A much more affordable program is PhotoShop Elements, something that I
used at a previous job. It costs a lot less, somewhere over a hundred
dollars, and is quite capable. I used to call it "PhotoShop Lite" but
it still does a great deal, and probably more than you'd ever need at
home.

It is apparently the successor to the very old Adobe PhotoDeluxe Home
Edition, something I still have on my computer and use from time to
time. Although quite old, PhotoDeluxe Home is still very good for a
lot of those simpler functions and does a lot more. I've seen it
bundled with scanners and such a very long time ago, and it may still
be available in some places (used, of course). Very old but still good
if you can find it very cheaply. And there are some good prices on
eBay for older versions of PhotoShop and PhotoShop Elements.

A lot of the Adobe photo products are available on a subscription
basis, but that quickly runs into a lot of money if you use it for
more than a month or three.

Finally, here's a freeware product many of you probably know about,
IrfanView. You can download it from:

www.irfanview.com

It really does a lot, and it's free for noncommercial use. They do
accept donations, suggesting 10 Euros. (It's about the same for each
seat if you pay for a license for commercial use.) I used it so much
and found it so useful that I made the suggested donation years ago,
but you don't have to.

In case you're wondering about the name of the program, Irfan is the
guy's first name. Born in Bosnia, he currently lives in Austria. If
you already have it, you might want to check what version you have and
maybe upgrade. The latest is 4.38.

Re: drawing program.....

David Donaldson
 

Another free possibility is a program called GIMP. You can google it and you'll find it on Sourceforge. It is an open source program and it is totally free. It is used extensively in the Linux community and it does almost everything that Photoshop can do. It is available for PC and works quite well. I used it extensively in the past.

Sorry if it was mentioned earlier in the thread.

Hey all!

 

We have some rain passing thru town this evening – no thunder or lightning yet, but who knows what will happen, so I will most likely *NOT* call the sideband net this evening.  If there’s any of you out there who want to jump in and call it, please feel free!

The Four State QRP Sideband net meets every Monday night at 7:30pm Central Time.

 

NCS is WQ5RP, with Jeremy, NQ0M as control operator from Beautiful Downtown Iola, KS.

 

Frequency is 7.285 MHz, QSYing down as needed to avoid traffic.  Check QRPSpots for the actual frequency of the net!

 

I will hopefully be trying out a new antenna this week, so we’ll see if people hear me any better this time around.  New antenna is a 54-foot random-wire end-fed with a matching network, then coax to the shack.  If I don’t have decent luck with this attempt, I might just spring for a PAR end-fed 40m antenna!

 

Hope to hear you guys tomorrow night!
