RMRc 2200z 14.0625 and 2245 - 7.0625

Dale Putnam
 

Your handy (maybe) dandy (not so much) NCS is still working with a temp antenna, so bear with me, while we all practice 
our cw skills. I'll match your speed, and you get to talk about... well.. what ever you want to talk about.
And, listen to everyone else check in too.. then I will go back thru the list.. to get each of your comments.
Another way to say it.. check in.. then stand by and listen to the rest get checked in.. then listen to all the comments,
until NCS calls you.. then make your comments at your own speed. 
  IS this different? Yes... it is, and if you want to tag in comments about one of the other stations comments.. feel 
free to do so.. that is what it is all about.
  See you at 2200z

AND.. at 2245 or so, I will call the RMRc on 7.0625  and we'll do it again.
 See you this afternoon!!

Have a great day,

I will contact this gentleman - he's in my neck of the woods.  Honestly, if he's planning to test with us in Iola, I'm surprised I have not already heard from him - since I coordinate the testing sessions for the club here.

Greetings Larry,

I am a green ham and actually I just ordered my first rig a ICOM IC-735 with the PS-55 power supply.  Now in my shack I am set up; I have a 40' tower with a 25' Solaracon CB antenna that goes to my "rci."   I am confused on what would be a good multi band antenna that I can homebrew.

I am in Garnett, KS; in two weeks I will be testing in Iola, KS.

Need advice from everyone please.

LCD and Bezel Installation Notes.

WA0ITP
 

For me, a freqency display has become almost a neccessity. No better way to get
that than to install an LCD. However it's always been a challenge to make them
look nice. Usually I just cut a hole in the panel, stick the face of the LCD
thru it. That's not very attractive and our projects deserve better treatment of
this very important feature.

Long time friend and super builder Dave Rogers, WB4CHK, came to the rescue with
some explicit and well thought out notes on LCD and Bezel installation. I
originally posted them on the AT Sprint reflector, and now have uploaded them
for all to use when needed www.wa0itp.com/lcd_installation.html

Turns out that it's quite easy to accomplish. I had a mental block thinking the
LCD protruded throught the bezel opening, it doesn't. The bezel's only function
is to cover the edges of the hole in the panel, the LCD fits behind it. Dave's
notes make that clear. You can also link to the page from my Tips, Tricks, info
page. http://www.wa0itp.com/tipstricksinfo.html

Hi Everyone,

I couldn’t remember if this link had been posted on the WBR receiver.  One of my friends, Serge Bertuzzo loves his and has a ton of fun with it.  http://arp75.free.fr/PortailARP/file/2011/n1byt%20_wbr.pdf  The original article is also in the August issue of QST if you prefer to download that off the ARRL site. 

 

A few years ago some might remember me having a few tube regens at Ozarkcon using the 1625 tubes configured for space charge.  Using “space charge” allows the tube (aka value) to be operated at very low/safe voltages like 12 volts for both filament and plate.  Not sure why there is not more write ups on space charge on the internet, but most of the old timers have heard of it. 

 

The performance of the 1625 is stunning!  Once you get a station tuned in, it is like there is a lock for the carrier.  I forget why this happens, but I sure noticed it.  This sure draws in the young folks that have never seen a real tube before.

 

Here is the basic design for the 1625 tube.  http://makearadio.com/tube/1625-allwave.php  This is a great site for those wanting to homebrew with tubes.  Like the QRPers, Dave has a ton of fun making these radios!!  The Bogen transformer is still available, so don’t let that keep you from making this cool rig.  I use a powered speaker instead of the high impedance headset.  Like everything in ham radio kingdom, some think using anything less than a real high impedance WWII headset is sacrile gious!  I prefer to give my earlobes a rest, hi.

 

BTW, for the new hams the 1625 is just a 12 volt version of the famous 807. 

 

Have fun and 73 de w5jay/jay..




Re: Regenerative receiver thoughts

Bill Cromwell
 

Hi Shawn,

I'm posting my reply to the list as there are probably others interested. Tubes, especially receiving tubes, are plentiful and quite often cheap. However, I have paid an average of seventy five cents each for tubes at hamfests and on eBay after considering postage and after the defective ones were removed. Some batches cost me a little more. Some a little less. Now..I can buy bipolar transistors by the dozens for that dollar! FETS not much more. Integrated circuits are a bit more. RF power costs a little more and serious RF power costs even more whether in vacuum tubes or transistors.

A big consideration playing with vacuum tubes is the higher voltage involved. Touching the wrong thing at the wrong time "under the hood" will at least get your attention! The voltages there could kill you. The more lethal risks are associated with transmitters (much higher voltages involved). Being bitten by a "modest" receiver power supply can cause damage if not death. You won't like it one bit. Some of us learned the safety rules first thing and live by them. Things like insulated floor mats and keeping one hand in a pocket while working on live circuits. Procedures like connecting the meter with power off and then then standing clear while applying power for the reading. Things hams would never waste time on working with a handful of transistors and a puny nine volt battery. Probably that has saved the "tube guys" a lot of transistor smoke as the same safety processes are much safer for the parts, too. Something anybody should consider before playing with tubes. Learn the safety rules, use them, and you will find quite a bit of enjoyment. Having pointed at this I can add that tubes in receiving applications can be operated with much lower voltages and some of the "battery tube" heaters use less power than a flashlight bulb.

Tubes have a built-in operational overhead that transistors do not have. The tube heaters, the pretty glowing part, can use as much power as some entire QRP rigs! Those do nothing but make heat and a pretty little light. The heat is *required* but to get any useful work from the tube you must apply even more power. Tube efficiency is never going to win against transistors doing the same job. Not ever. Tubes may have some advantages in some functions and they are much more robust if subjected to overloads for longer periods than transistors. Nobody ever lost a vacuum tube RF amp in the front end of his receiver due to static!

I encourage anybody and everybody to build there own gear. One of the fundamental things about homebrewing that doesn't get much press is "use what you have". You can get a basket full of transistors pretty dern cheap. You may already have a big pile of them. That also applies to skills. If you already know how to use transistors (or tubes) and you already have some of them then that is what you should use. Build it, tweak it, get it on the air. Then brag or even gloat <evil grin>.

A final comment about the regenrx list. Yes, there are more tube enthusiasts there than solid state enthusiasts. If more solid state enthusiasts joined up that balance would change <hint, hint>. Those people would be welcome.

Bill,
Thank you for your bringing together any gap in understanding one of each other. My experience with tubes began when I was a kid. (born in yr. 55). Maybe I was hiding behind the TV, (black and white), but I would be attracted to the glowing tubes of different sizes. I also, learned to wiggle the ones not on - and the tv would work, once again! There were tube testers in practically every store. That was always fun to take a bag of various, shine underneath the dust, dead tubes-to the store, with my parent, hoping to bring the television back home, back to life again. Here is my mis-notion; That tubes were finally replaced with "something else", and the old tv just had to go, for it had become too difficult to find any of what you needed to gain a last gasp of breath out of a dying glow on things. I still like the glow of a tube, the only reason I have not ventured that way, as a rf collector, is I didn't want to pursue, (as far as time management), learning about tubes, thinking that they are in low supply, and difficult to find. That's how little I know, and I am hoping now to find out from you, --if the tubes one needs for today's hobby are live and well? Thanks, Shawn. kf7yff

"building something without experimenting is just solder practice"

Hi Jerry,

I think this is a misperception on your part. The misperception may stem
form some factual details. Regens are what might be called "retro".
Vacuum tubes are what might be called "retro". Hams who are interested
in those things are interested in things that are "retro". That interest
shows clearly. I hope that is not considered "discouraging". I have not
seen anybody discourage another from using solid state designs in regens
or associated circuits.

The only cautionary statements have been along the line of not
unplugging vacuum tunes and trying to install transistors - especially
bipolar transistors - directly into the vacuum tube circuits. FETs work
best when abused in that manner and even those need some adjustments.
That shouldn't be a surprise if you consider that just changing to a
different tube type will probably need some tweaks, and sometimes even
for a different tube of the same type. That shouldn't be discouraging at
all. After all -

"building something without experimenting is just solder practice"

<grin>


If you look at the files and photos sections of regenrx (and the
overflow in regenrx2) you see a lot of solid state regen projects.
Another message in this thread references the Wein Bridge Receiver, aka
WBR, and that has been discussed and documented in the files and photos
section. By the way, WBR is solid state. So have regen receivers
inspired by Kitchen and his solid state designs. More than a few others.
A statement that solid state designs are discouraged there seems
unfounded. Even if more than half ARE vacuum tube designs. There is just

Hi Jerry,

I think this is a misperception on your part. The misperception may stem
form some factual details. Regens are what might be called "retro".
Vacuum tubes are what might be called "retro". Hams who are interested
in those things are interested in things that are "retro". That interest
shows clearly. I hope that is not considered "discouraging". I have not
seen anybody discourage another from using solid state designs in regens
or associated circuits.

The only cautionary statements have been along the line of not
unplugging vacuum tunes and trying to install transistors - especially
bipolar transistors - directly into the vacuum tube circuits. FETs work
best when abused in that manner and even those need some adjustments.
That shouldn't be a surprise if you consider that just changing to a
different tube type will probably need some tweaks, and sometimes even
for a different tube of the same type. That shouldn't be discouraging at
all. After all -

"building something without experimenting is just solder practice"



If you look at the files and photos sections of regenrx (and the
overflow in regenrx2) you see a lot of solid state regen projects.
Another message in this thread references the Wein Bridge Receiver, aka
WBR, and that has been discussed and documented in the files and photos
section. By the way, WBR is solid state. So have regen receivers
inspired by Kitchen and his solid state designs. More than a few others.
A statement that solid state designs are discouraged there seems
unfounded. Even if more than half ARE vacuum tube designs. There is just
no way around the efficiency advantage transistors have over vacuum
tubes. The mere presence of vacuum tube designs should not be discouraging.

Finally, there are some hams who are more comfortable with vacuum tubes
and do NOT know what to do with transistors - or are inclined in that

Bill,
     Thank you for your bringing together any gap in understanding one of each other. My experience with tubes began when I was a kid. (born in yr. 55). Maybe I was hiding behind the TV, (black and white), but I would be attracted to the glowing tubes of different sizes. I also, learned to wiggle the ones not on - and the tv would work, once again! There were tube testers in practically every store. That was always fun to take a bag of various, shine underneath the dust, dead tubes-to the store, with my parent, hoping to bring the television back home, back to life again. Here is my mis-notion; That tubes were finally replaced with "something else", and the old tv just had to go, for it had become too difficult to find any of what you needed to gain a last gasp of breath out of a dying glow on things. I still like the glow of a tube, the only reason I have not ventured that way, as a rf collector, is I didn't want to pursue, (as far as time management),  learning about tubes, thinking that they are in low supply, and difficult to find. That's how little I know, and I am hoping now to find out from you, --if the tubes one needs for today's hobby are live and well? Thanks, Shawn. kf7yff
