Now they are target-rich with signals that just may be discernible with a $14 gadget piece of equipment. When this converter was designed, those bands, and the new-fangled digital modes that now fill them, did not exist. I couldn't help but wonder - is it possible to receive 630m and/or 2200m signals with such a simple and low-cost device?

Although the cut-off frequency of the input filter to the converter is just above 300 kHz, the manual for the converter describes how to determine the values of the L and C components to change the filter's characteristics. Until today, when K0OD and AA2UK forward biased a few neurons in my memory when discussing ways to receive signals on the two new (in the US) ham bands. I put it away and forgot that I even had it. I built the kit and remember hearing noises, squeaks and other emanations from the ether, but, as is sometimes the case with this blog, little intelligence could be discerned. Then (and surprisingly, still now) Jackson Harbor Press offered a very inexpensive kit that converts 100-450 kHz up to the 30-meter band. Years ago - maybe 20 - I had hopes of experimenting in the 'lowfer' band of 160-190 kHz. If you've tried receiving signals on the new 630 meter band but have heard little or no activity, there is an easy and surprisingly inexpensive solution - and last night's testing proved it to be a very effective solution as well. Does your main station rig lack sensitivity on frequencies below 160 meters? Most do due to filtering designed to prevent QRM from the AM broadcast band.
