Softrock Receiver

To be honest, I'm not even sure exactly which model of Softrock this is. I can tell you that it is one of the earliest ones and that it works just fine. I have the 20 meter and 40 meter plug-in modules for it, along with crystals for 14.060 MHz and 7.030 MHz.

NJQRP 4:1 Current Balun

This is built from the kit produced from NJQRP a little over 10 years ago. Never ended up using it much, but it should be good for up to 100 watts in the HF bands. The manual is here.

  1. How is the DG1022U working out. I don't know how recent your post was but it cant be too old as the little generator is relatively new.
    I am a hobbyist and I just got a new Rigol scope. Now I want to get a small function generator. I am 73 yrs old so I am wondering how complicated the instructions will be for me. I am just getting acquainted with the scope and I think I can figure it all out. I was pondering over the idea of a used Wavetek for a couple of hundred dollars or spend $400+ for a new Rigol. aybe you can give me a few pointers about the 1022U. I have a few old receivers here that I want to experiment with sweeping the IF's to --- Just learn how to do it, I guess.
    Anyway I enjoyed reading your post. I think it is more along my way of thinking. I read a negative review on an EE website and I think a "ham review" is more of what I was looking for.

  2. Phil,

    So far I'm happy with my purchase of the DG1022U. I've used the basic CW signal generation purposes, and it has done that job quite nicely. When set to -50 dBm and paired with my HP step attenuator rig, it can provide a signal down to about -130 dBm or so.

    I have briefly tried AM modulation, just to see that it works as expected. It's actually quite amazing that it gives you AM, FM, PSK, and FSK. Not to mention PWM and other pulse-train type signals. And I haven't even touched the actual arbitrary waveform generation yet.

    There is been some concern expressed to me that since the unit is based on DDS technology, the spurious emissions might be problematic. Now that I have the DSA815, I plan on checking out how the spurs look on integer MHz frequencies, which tend to be problems in DDS systems.

    It also has a built-in 200 MHz frequency counter, which is quite handy. If you pair that with the USB connectivity, you have an automated oscillator stability measurement system.

    If you want to sweep circuits, it does have a sweep setting and a sync output, which you could pair with an oscilloscope or a spectrum analyzer without a tracking generator.

    Like I said, I have no complaints at this point, but I haven't really put it through its paces yet.
