Tom K0AMD,

For me the mini60 has been a most helpful addition to my "test bench".
Some years ago I built a 30 Meter station - Xmtr/Rcvr - based on circuits drawn from ARRL's "Solid State Design, for the Radio Amateur" by the venerable Wes Hayward, W7ZOI and Doug DeMaw, W1FB.
My most advanced piece of test gear at that time was the Heath Kit  solid state dip meter. 

I find the mini60 helpful for a variety of purposes not least for adjusting my antenna(s) to minimum SWR at their feed points. After that I use a tuner to match the coax/balanced line at the xmtr output. 
The mini60 battery life doesn't seem great. Just be mindful to have it fully charged before you "climb the ladder".


(While on this subject I have a question. I can adjust my antenna (trim the length/experiment with counterpoise length and positioning) to achieve quite acceptable SWR levels of 2:1 or lower. Using my tuner at the rig I can lower the SWR to 1:1. Signals sound stronger when I bypass the tuner but is that due to noise and not signal levels. Sometimes my power output reads higher than when I bypass the tuner to the antenna directly.)  When does it matter and when does it not matter when/if I bypass the tuner. Why?)


So much sophisticated yet reasonably priced tools are available these days. I own a Tektronix 2430 scope which I purchased a few years ago for "cheap" on e-Bay. I haven't found the time yet to fire it up. Looking through the adds for modern day test gear (at reasonable prices new) I've wondered if it would be worth breaking out the old 2430. Why not go for a current and quite possibly more accurate and with many more "bells and whistles" test "appliance"? 

There is a lot to be said (not everything mind you) for simplicity. QRP operation is a prime example. It allows us to get down and dirty with the fundamentals of the art and science of radio. That's why I will attempt to get my 2430 up and running. Even if I fail I'll still have learned a lot in the process. Maybe the mini60 has been out there long enough now to make them widely/cheaply available used. If you've never used an antenna analyzer before, this could be your opportunity. I haven't even used many of my mini60 features yet including interfacing with a computer. 

These are just one ham's personal opinions. Goals not imperatives. Ham Radio is a river broad and deep. We stand on the shoulders of giants whomever we are and regardless of our expertise.

I've had more than passing success working back East /Mid-West/South-East/ and North to Alaska using my all bander doublet.

I have an original SS-40 Receiver, NS-40 with a 4sqrp VXO switch selectable in the same case and the Magic Box which I am ready to part with. I haven’t used them for some time but am confident they still work. Each are built into their own case which I fabricated from sheet metal from a microwave cover and computer side covers! They look pretty good if I have to say so myself.

Subject: [4SQRP] Hilltopper Mods

Folks-

Here are several easy mods to improve Hilltopper performance. They address audio levels and quality.

1)   'Loud sidetone':

The value of R8  (now 22k) can be increased to 47K to 100K.  (This change has been posted before, but it's worth including in this summary )

2) 'Low audio'  

The values of R5 (150K) and C22 (470 pF) may be changed to 330K and 220 pF respectively.  This yields a gain increase of 6 dB without affecting that stage's rolloff characteristic.

These two components are in 'tight quarters'- between U3 and the pushbutton switch.  Cutting one or both component leads and tacking the new components on the underside of the board makes the change much easier. 

 But wait- there's more!......

As some of you have noted, there's a 'screech' on loud CW signals- it necessitates riding the gain control. I evaluated samples of a more robust op-amp-  the NJM4556AD.

3) Replacing the NE5532P with that new device eliminates the screech. You'll hear some distortion when limiting occurs, but it's much less objectionable than the NE5532's rude noises. Its 'limiting' threshold is also about 6 dB higher than the present device.  The net result of this change, combined with 2) above,  is 6 dB more audio without the rudities (that's a word!).

Note that if you increase the gain without replacing the IC, you'll find yourself riding the gain control more often
------------------------------------------------
Here's the deal:

If you'd like parts for fixes 1) and 2), simply send me your address and I'll drop them in the mail to you.

I can provide the NJM4556AD as well, but I'd need to charge for it at my cost.  Most of that is postage- nearly $4 for a 'non-flat' mailing these days.   This part is also readily available through Digikey and Mouser.

I’ve got a Cricket 80a with marking, © 2017 that I bought a couple years. It’s all built up. Transmitter works. Receiver works for about a second after power or key up and then fades. It is probably something simple but for the life of me I can’t find it.

 

Everything is there except the key arm which I stole to use in another setting. The one with the key jack on it is mounted.

 

If someone is interested in it make me a modest offer and I’ll likely accept.

Yes, Ozarkcon is a lot of fun - I really look forward to it.

Maybe you can try to work the K0N station they set up at the hotel.
