Cricket 80a for sale

Martin
 

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.

 

Thanks,

Martin

Johnny AD0BQ,

Thanks for the comeback. Hope we QSO.

We are in a sunspot nadir like I've never experienced.
I've been active long enough to remember some real halcyon DX days.

QRP rig FS

Paul Goemans
 

Hello all,
  I am thinning the herd here. Selling my fairly rare S & S Engineering TAC 1 (40 meter) monoband transceiver. A groundbreaking QRP rig design in 1995; a PLL synthesized rotary encoder knob tuned transceiver with an LCD display, rugged aluminum case. I connected it up this morning, heard a CQ, one call, a QSO! Puts out about 4 watts on a gel cell battery, probably 5 watts with a 13.8 volt power supply. Complete with original construction/ operation manual and (optional) internal iambic keyer board. I am not the builder. So there are a straight key jack and an iambic key jack on the back panel! Keyer control pushbutton also on the back panel. Tune knob is used to change keyer settings. Tuning rates 1 kHz and 100 Hz, RIT, narrow AF CW filter. Shipped to US address for $160 PayPal or money order. A fun rig!

Dear All,

Been reading the (blog) mail. 
Most interesting. Most helpful..

Enjoyed FB "Hilltopper 20" QSOs over the weekend with ...

W3NP    WV
W3PP    PA
AA0AI    IA

My regular antenna is an all band doublet, window wire fed, oriented East/West.

Getting ready for portable operation I did QSO with AA0AI(IA) using a mobile antenna and counterpoise.
He was calling "CQ 'AS'" but was kind enough to come back to my "CA" call.
I won't do this again. Got to live with myself.


Best of luck with Ozarkcon QRP Convention April 5-6, 2019 in Branson, MO.
Will follow at a distance this year with hopes of attending next time around.

Glad I found you guys and gals,

Fellow members:

I have the following for sale and am traveling down I-44 Thursday from St Louis to Wichita Falls so I could deliver down that corridor. First is a Heathkit HW-101 with power supply speaker and microphone. Second is a Hy-Gain tri-bander. Both are in good shape. I would like $350 for both. Please text me at 8067891378 or email me at richard.dickerson@...

Hilltopper mods - 'how to get them'

Dave Benson
 

gang-

As my original post mentioned, fixes 1) and 2) are free for the asking.

Please contact me directly for these:   davek1swl at gmail.com
-----------------------
The price for all three is $7 via Paypal (A check's fine too)  The big difference is the need for a padded mailer, po$tage and Paypal fee- those alone add up to $5.

For this flavor:  Paypal to my e-mail address above.
-----------------------

I'll be able to ship later this week- I've just reordered parts

VK3YE 716 Receiver

Curt
 

I am listening on 40M CW with receiver built from VK3YE circuit Dec 2017. It uses 2 transistors, a 386 audio chip, 716 resonator, three diodes for the "varactor", three potentiometers,  and a home etched circuit board.  After finally putting it into a box, have been listening with it.  For something so simple, ( and cheap ) the performance is amazing, stable and sensitive.  Tunes 7.028-7.070.  Started here http://home.alphalink.com.au/~parkerp/projects/projresrx.htm

Calling all Stompers,

Pull on those QRP Boots and get set for this annual fun event.

Check it out at:

https://sites.google.com/site/pnwqrpgroup/sasquatch-stomp

Remember the re-birth rule and do remember that QSOs with non-stompers count
too. For those, use the RST numbers you received in place of a Sasquatch
number.

Hope to work you in the Stomp.

Re: Hilltopper Mods

Dave -

I would also like to make the mods you list. In addition, I would also like to have another pushbutton switch. I will gladly pay you for all parts, including shipping.

Tnx, Paul, AI4EE

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.

Re: Dummy Load Antenna

n5ib_2
 

About two years back I made an OzarkCon QSO Party dummy load out of NiChrome wire. Measured off enough to have a DC resistance of 50 ohms, which was about 50 inches for some fine gauge stuff I had here. It formed into a loop about 17" in diameter, using some polyethylene tubing to define the shape. Since the RF resistance would be somewhat higher I re-measured the formed loop with an antenna analyzer and trimmed for close to 50 ohms resistive part at 7 MHz. The loop, of course, has some inductance, and it took about 200 pF in parallel to tune out that reactance.

Some small PVC pipe and fittings to make a suitable stand and it was ready to QSO. Alas, I had so much fun chatting and visiting that I didn't put it on the air for more than a few minutes.

If you don't have any NiChrome you could achieve a similar effect by stringing a few resistors end-to-end in series, maybe with some wire between them to space them out enough for a loop a foot or so in diameter.

Jim, N5IB

PS... also check out in this group's Files section "Quick HF DF Loop.pdf " uploaded Feb 9 of 2017, as an idea for the oscillator hunt.
Re: Dummy Load Antenna

Dwayne R <masterdr@...>
 

that isn't a dummy load. . that is a full fledged antenna. . .
The 50 ohm is used to insure a impedance match to the transmitter.

you can do the same thing with very large loops. . .. measuring the
resistance of the wire per 100 feet, and building an antenna that is
long enough to equate to 50 ohms. . . .

No tuner needed. . .

My
interpretation is that one end of the zip cord is soldered

ft.  One end is then connected to the BNC ground and the
other to the resistive load.  Is this interpretation
correct?
Thanks for your help.
