Once the tube is mounted, mark the tube pin configuration onto the breadboard keep in mind that the datasheets list the pinout as a bottom-view of the tube. I neglected to remember this, and as a result wired the tube pins backwards.Again, you will need a high-quality splitter cable that has a frequency range within your interests. To split the signal, connect the splitter to the adapter and plug the adapters into each antenna. Then, connect the radio to the adapter using the SL 239 connector. This will split the signal between the two antennas and allow the radio to ...

Attach the audio amplifier to your crystal radio. Slide the battery cover off the back of the amplifier (in the direction of the arrow), and install a 9 V battery. Replace the back cover.

Any antenna that is less than 1/2 wavelength long and less than 1/2 wavelength high will start to loose efficiency when shortened or lowered. (1/4 wave verticals must also be at least 1/4 wavelength long and have an almost perfect ground plane). So for HF frequencies if you want to go a similar route you should look into magnetic loop antennas.David, WA7JHZ has designed and assembled this neat 2.6 MHz high-pass filter (HPF) for use with SDRs.

I've noticed recently how much improved my shortwave reception is with the 15-foot wire antenna that came with my radio (although I still don't pick up much), so I figured it would be a good idea to build a longer antenna of some sort. I did a bit of research on the wiki and such, and came up with this page.through radio equipment dealers or online. It is also available in many sizes and grades, which can be confusing. For the shortwave listener or Amateur HF operator, a good cable to use is called “RG-8x”. Unless you are transmitting using an amplifier, or working at VHF frequencies, this cable is more than sufficient for runs up to 150'.Figure 1.
