Don't see many posts and I enjoy reading them. Seems that the forum has been abandoned.

Not abandoned. I check it every day. Most of our fraternity seem to post on Dave's site these days. Over there one can include pictures.

After putting a huge effort into my previous post (re: PDF) and receiving no replies or interest, it was subsequently deleted.

I check quite frequently also. I just have not been very "radio active" lately.

Here's something interesting. QST recently ran an article in their vintage radio section about the IP-501 shipboard double tuned regen/xtal set. It can be switched to either detector type. An very interesting link was provided in the article on the 501 and related types:

The circuit diagram is visually busy, but once you boil it down to basics it is not so complicated.

Thanks for responding. I do have questions now and then and I am guessing that I will have to post them here. You see, I have been "banned" from "the radio board". No reason as of yet for this.

OK enough of that....

The question I have is that I would like to know if one can use melted solder to mount galena crystals. If I remember correctly, it will destroy the galena or something to that effect.

Senior, I've been banned permanently also and have not the faintest idea for this. I would imagine that we will eventually find out the reason. TRB has been hacked recently, so maybe they are banning all to straighten the problem.

Well, thanks for the info, That could be very well be the reason.

SW

It was the reason!

That seems to be the general opinion.
Adding a small bit of mercury from a old thermometer and tin foil will lower the melting temp a bit. I have not noticed problems with non resin solder but I wait until the the top starts to skim over before pressing the crystal in holding it with a copper alligator clip. (end wrapped good to insulate the heat from my fingers)
If you can find it Plumber's lead has a lower melting temp.
Homebrew woods metal (70 degrees):
2 parts Lead (327 degrees)
1 part tin
4 parts bismuth
1 part cadmium
Look for old topics here. Low melting point materials bought at gun shops and on line have been mentioned a couple times.

I seem to be able to view the radio board while not logged in with the new format.
Can you watch the posts now?

What are the commercial galena crystals mounted in?

Are they prohibitively expensive? I would purchase rather than deal with mercury or hunt all around for stuff.

Test.

Test.

OK, here's the message I just got from posting "Test":

Server object error 'ASP 0177 : 800401f3'

Server.CreateObject Failed

/rapntap/post_info.asp, line 92

800401f3

The way around this is not to go "back" in any way, but to go into the Rap N Tap site from the beginning and click through to this thread.

Posts are being made OK despite the message. Or at least for me so far everything is posting the first time and I just go the long way around back in to here.

But in doing this test I just found out you cannot edit one of your posts. It drops whatever you try to post.

Hi Friends,
On my forum we did a major upgrade of the software. Inasmuch as the admins had no experience with the new features, we did some things that turned out wrong. First of all, let me state that no member was intentionally banned. We were banning spammers, but unfortunately some IP addresses matched our members.

But we found a good way to keep the spam out, and the members in. If anyone finds themselves still banned, please go to my radios website and send me an e-mail. As you know, I have been very dedicated to my forum and would not want to make anyone unhappy ever.

Sorry for posting here about another board, but I want to make sure that everyone is as happy as they can be.
