Thanks Ben for the new cores!

73, Kevin NZ1I

I've got an old RxTx 6.3 that I've got some real uses for now (it had been shelved for a while). I will be setting it up to work only on 10m. Does anyone have the transmit and receive piggyback boards (amp and filters) that I could get?

I don't have the means to roll my own, and I'm on a very limited fixed income. If I can find the boards, it will put a really decent radio online again.

Thanks!

Mike,

I did try this

I got stuck with programming my (fake?) Trinket but obviously it worked for the author:-)

I think I am going to try this. I've learned the AVR toolchain, played with the Si5351 library by NT7S.
The change looks doable so far - just rip out the PLL parameter calculation for Si570 and replace with different ones for Si5351A.
But I am sure there are gotchas on the way.
One thing I don't want to learn is Windows programming for the control software (cfgsr-setup). But it would be nice to have at least some functionality of it, like burning the initial frequency to EEPROM.

Maybe somebody did this conversion already, or at least tried? Any tips?

Their are now Lite kits available on softrockrx.com
great panadapter.

Most Softrock information is in the files, 6.1 /g/softrock40/files/%27A3%20RXTXv6.1%20files

Dear all:
A friend gave me a bag with the components of an old SoftRock RXTXv6.1 kit, but the CD inside is unreadable. Would any of you have, by chance, the contents of this CD so that I can have a shot at building the transceiver?
Thank you very much!

I just had my Ensemble RXTX II change its operation behavior. I did hear a popping noise and then the frequency band displayed on the SDR software was compressed to a small portion of the displayed band width. It should have been 96KHz for my computer sound card and software settings. Attached is a png image screen shot taken when Quisk software was running with the Softrock RXTX. Even though the displayed band width was small, I could hear some SSB transmissions (though distorted) coming through.

Has anyone seen this behavior and what is the cause and any remedy?


Sorry, the screen shot would not attach to this message.

Thanks all for the help!

RXTX kits are now in stock!
Quantities are limited, But I will try to keep them in stock from here forward.

PM me your mailing address and I'll put one in first class mail for you.
I bought the latest batch from kits and parts, it's hard to beat their prices and service.
Have you read the instructions at ?
They have some links there also for winding the coils, watch your wire sizes, several of the kits have 2 different wire sizes.

You can order them from kitsandparts unless you're looking for a single one.

Hi Folks,

I am building a RX Ensemble LF and while winding T-02 I broke the Core. I
had it in a vise for winding but crushed it.

So if anyone has a Binocular Core BN-43-2402 , Please let me know.

I have not yet looked to Mouser etc.

Also, if anyone has any Hints for winding this 7T/3T bifilar inductor that
would help too!

Thanks and 73, Kevin NZ1I

Got your message. Seems to be working. Gotta say as an aside, I enjoy the
softrock v6.3.

Hi Alan

Finally got the Ensemble RX fixed. Used PE0FKO v15.15 (latest), no issues so it seems backwards compatible with v15.12.

Built a Ponyprog serial programmer and used avrdude v7 on Linux Mint 19.3 to programme the ATTiny85.

All seems to work fine. The sensitivity is a few dB down on 10m, but can see the band noise from the G5RV so no problem.

Thanks for the support.

In excellent condition and working order. Comes in KM5H enclosure. $75 plus shipping. Email is OK in QRZ.

Oh Good.

I do not understand this. What is the "filter value" and the "band value"? Should I be using 15.12 or 15.13 on this Ensemble RX Mk I?

Nick

My quick guess is that it concerns custom band selection, not normally used for most Softrocks but available for other builds.
CGFSR is used for other projects.
Just use the last release. Was that 15.15?

Nice to see that pe0fko.nl is up and running again - thanks Fred.

About ready to program the ATTiny85. The old one was running Version 15.12 of Fred's firmware.

This page



talks about a bug in 15.12 that was fixed in 15.13...

"Version 15.12 uses the filter crossover table to select the frequency band, for every frequency band (0..3) the filter number (0..3) used can specified. Only by a bug in the software, the output lines are not put in the requested filter value but the band value. The bug is now fixed (by changing a #ifdef to #if statement in DeviceSi570.c). "

I do not understand this. What is the "filter value" and the "band value"? Should I be using 15.12 or 15.13 on this Ensemble RX Mk I?

Nick

PS: It seems that there is no advantage in using 15.14 or 15.15 for this radio.

If anyone knows of where building support documents still might be found

Brian,

Robbie's site is still up

And schematics are in our files, /g/softrock40/files most have transferred safely from Yahoo.
