Problem loading jic file - Not a valid sof file error

[Jim Smith]

Glenn,  

Did you download it in the correct format?  See "Problem loading jic file in JTAG Programmer" thread starting 26/2/15.  Seems it's possible to download the file in the wrong format, even though it says its a *.jic.  I've fallen down this hole also.

Graeme suggested that a new .jic file is required for this Tx out version.

I now have 'Hermes_Lite_TxDAC_CVC8_73.jic'     [i have a cv8 with the 'c8n' suffix & 73Mhz osc]

However, using Quartus, I cannot program the CV8. 

 I get an error when trying to load the .jic file "not valid SOF file"

any ideas?

Some test results in Tx mode.

Using the OPA 2674,  PowerSDR with drive at 100%. T2, 4t bi-filar on BN43-2402 core. 12V supply.

Has anybody else tested this?   I wasn't expecting low power on lower bands like this.

OBSERVATION OF v1.42 RF PCB:

the mounting hols are in a different place to V1.32 pcb.
Can't plug it in and fit the screws.

Thanks Graeme, 

I just wound mine up on BN43 core.. I used 0.2mm wire which is a bit tight, but do-able.  (smaller guage wire is hard to get here))

 The centre tap hole in the PCB would be better, if it was same size as the other holes also.

Here is the info in the frontend.html file in github

Build Option: Transformers

Transformer T1 is an 8:1 Z with the low impedance side towards the SMA. You can use a commercial part MABA-010143-FLUX18. Or you can wind your own by following the directions for the 1.2 board. Transformer T2 is a 1:1 wound on a BN-43-2402 core, four turns bifilar. It can carry half a Watt and there is no good commercial substitute. It provides good performance from 1.8 to 29.7 MHz. If you have only BN-61-2402 cores, try to wind 11 turns, or as many as you can manage. For lower frequencies like the new 630 meter band, you will need a transformer designed for lower frequencies.

typo, should be T1 in this line below, of course

Somewhere, this info for T2  is embedded in all the many posts, but so far I cannot find it again....I think its important we all build the same, if using homebrew.

Unfortunately they (BOM) are no help for homebrew for T1.    They give a makers part or 'homebrew'

For T2 I found 4turns bifilar on BN43-2402

See frontend/v1.42/frontend.html for the transformers.  Or the bom frontend/v1.42/frontend.csv.

Thanks Jim.

Yes its very easy to download what 'seems' to be a jics file as the extension and name look like one, but instead of right clicking to save such a file, one has to click on the file name which brings up a new page in Github.
THEN click the RAW button to download what is about a 2Mb file. (not a 46kb !)

Its so easy to do the wrong thing here especially if one does not fully understand Github, like me......
