New kits arrived

It took a while, but I now have "a few" kits to build.

Some SoftRock II kits, different bands, each can be made directly for 160,80,40,30 or 20m, all components in the kit. Some SMD soldering necessary, but should be possible, even with my eyes.

Some "Funkamateur" single frequency kits, among those a 10.7MHz kit to connect to my VHF-UHF RX (R7000, possibly AR-8600).
Two kits for 9MHz, one will be modified for use on 10MHz

the other 9MHz might be made "wideband", so a multitude of LO signals could be used, possibly a Si570 synthesizer or the DDS60 kit

Two lower band kits, to be decided

The FA wideband SDR TRX, will need a PA and a programmable LO, not yet ordered. Covering 1.7 - 30 MHz with preselection, so seems quite usable.

The "standard" 1W PA could probably easily be replaced by a home made solution, but I will see if I do not get to order the standard one at some stage. The local oscillator, the so-called FA-SY may be the way to go for full band coverage. A housing is also available, I may order that one, too.

Update :
The FA-SY oscillator has been ordered, along with a housing fit for the FA-SDR TRX
More Update :
The FA-SY kit and the housing have arrived

Lots of kits to build, not too much time, so let us see what comes up here.

The intention is to use some of the fixed frequency stuff for simultaneous WSPR and QRSS monitoring.

Idea Box : Long Wave SDR

I found those 4.224 Crystal oscillators (ex equipment) on eBay .

Divide 4224 by 32 (first 8 and then make the quadrature signals), and the LO frequency ends up on 132 kHz. Not bad for a 136 kHz SDR.

80m SDR, p2

More solder smoke released, only missing the ICs and the oscillator - I am going to leave out the oscillator and make a local oscillator input, making a switchable Local oscillator possible.

Now for some more reading.

Building SDR for 80m

Today I received the kit from the magazine "Funkamateur" with all necessary parts to build a "single frequency SDR", similar to the SoftRock, along with a few other components for my constructions.

Like for Joachim, one resistor had a 1000 times larger value than the one needed. No problem, since I had one of the correct value.

Some solder smoke generated, not quite finished yet, but it is time for some reading.

Back to some radio stuff

I have been away for about a week and I am back from the holidays. My spare FT-817is now here and will be set up for WSPR/QRSS and other experiments, while soldering.

I know there is some stuff waiting for me, eg. a "single frequency oscillator" SDR kit like the softrock design, that I will solder as soon as it is here.

I do have quite a bit to read in the next month, so the radio activity will be somewhat limited. I will have to solder a bit between th words ;)
