Good Morning All,

I have fifteen Version 4.0 SoftRock40 partial kits available for experimenters.

The kit includes the v4.0 PCB, the six integrated circuits required in the v4.0 circuit and two 2N3904 transistors. Also included with the kit will be print outs of the V4.0 schematic and top/bottom PCB copper. Might be just the kit you need to try the SoftRock40 on some other band or in some other application.

The cost of each kit will be $14 which includes the postage cost to mail the kit to your QTH. (USA/Canada or Europe)

Send me an e-mail if you would like one or more kits.

Thanks and 73,

Very sorry if you missed out on one of the SoftRock40 partial kits but
they are all spoken for at this point.

Thanks for your interest.

Subject: [softrock40] Battery power IS better. Photos prove it.

Apparently, my last message on this got lost in the server somehwere.

I have uploaded two new photos to the N1RX folder that show the
difference between powering the SoftRock from the USB port vs using
a battery powered supply.

Both photos show the central noise spike from an SR-40 connected to
a dipole antenna. The only difference between the two photos are the
source of power. In the first, the SR-40 is powered by the USB port,
using the standard Q1 power conditioner. In the second, the SAME SR-
40 is now powered by a 78L05 voltage regulator, driven by a battery.
Notice the difference in the width of the central noise spike.

Better performance from the SR-40 can be obtained by running from a
power source OTHER than the USB port on the computer. Battery power
is best. For details on how to modify the SoftRock to use non-
computer power, see the other photos in the N1RX folder.

Good Morning everyone.

I have posted two more photos to the N1RX folder. These show
the "noise spike" at the center frequency of a SoftRock-40. One
shows the spectra obtained when the SR-40 is powered in the original
fashion, from the USB port of the computer. This uses the original
Q1 power filter circuit. The second photo shows the EXACT SAME SR-
40, powered by bringing in external 5v, derived from a battery
supply, using a 78L05 regulator.

In both cases, the radio is operating on 40M, connected to a dipole
antenna. The only change between the two was to unplug the card from
the USB port, and connect the external power source using a couple
of clip leads. It is clear that better performance can be obtained
by using a seperate source of power for the SoftRock.

For details on how to modify the SoftRock for non-computer power,
see the appropriate photos in the N1RX folder.

SoftRock-40 round 2 kits in the mail

George Heron N2APB
 

Our kitting team lead reports that 270 of the SoftRock-40 Kits for Round 2 are now in the mail. The remaining
130 are waiting on the final semiconductor sub-bag of parts coming from the kitter, expected any day, and we'll
likely ship the last of the kits later this week.

Thanks for everyone's patience on our scramble to get this second round of kits out - what a great little
receiver with great big results!

Hi Kees,
?
At the moment I want to see if the partial kits, PCB plus the ICs, will sell as I liquidate my excess kit supplies.? If I have PCBs left over at the end, I will contact you and we can determine a price for only the PCBs.

Thanks for your interest.

SoftRock: 30m Crystals now restocked.

Bruce Beford
 

Hello everyone. I have been able to aquire a large quantity of the 40.500Mhz
fundamental-mode crystals required to move the SoftRock-40 to 30 meters.
After completely selling out of the original 100 I had, I was able to obtain
several hundred more. This means that there are now enough for ALL SoftRock
owners (including those with pre-AmQRP kits) to have on-hand a crystal or
two for 30m. Due to the large quantity purchased, I am able to maintain the
same price. (just recouping some of the expenses.) If you are interested,
you may order using the instructions below. PayPal, or a check to my address
listed at QRZ.com is OK. Just drop me an email if you are sending payment
through the mail, so I can reserve crystals for you.

73, Bruce, N1RX

Subject: SoftRock40 on 30M- Success! Crystals available now.


Hello all.

I have successfully converted a SoftRock40 for use on 30M. Two capacitors
need to be changed from their original values, and a new oscillator crystal
installed. Capacitors C6 and C7 (ver. 4.0 designators) are changed from
their original 100pF to 33pF. The crystal is changed from its original
28.224 to 40.500 Mhz. The original crystal still works with the new
capacitor values (in two units here). (I had tried this before, and didn't
think it worked, but my experiment was flawed. It is working now.)

I have available a quantity of the 40.500 Mhz crystals required. These allow
nearly full coverage of the Amateur 30M band with the SoftRock receiver. As
I announced earlier, I am making these available to all. The price for US
delivery is $2.00 for one crystal, $1.50 each for quantities of two or more.
For foreign addresses (including Canada) the price is $2.50 for one, $2.00
each for two and up. You may send payment via PayPal to
bruce.beford@... I will fill orders on a first-come, first served
basis.

Any questions? Email me direct, and I'll answer as best I can.

Interesting 40m frequencies

Re: SR-40 Software Compiler for free

Someone chose for some reason to use .Net and that is tied to the *crappy* OS. Also that software may have not been mature enough for serious use when they had to make a decision. Now that it's made it's very time consuming to switch.

Myself I'm a Delphi fan, that is available for Window and Linux(Kylix), but not for the Mac which is BSD on Power PC chips.

There is a Free C# runtime/development environment called mono.
