Be prepared and able to communicate in case of emergency with the largest selection at eBay.com. 80m Direct Conversion Receiver - SP3CCT I had one occasion of lockup with this sample of the H-501x. The antenna input circuit (RF front end) is simplistic, I did not use an RF pre-amp (LNA) or even more elaborate LPF / BPF filters and even so it is possible to get good radio receptions. Rather than using the reset hole, I decided to remove one of the two 18650 batteries, which of course reset the receiver. Low frequencies will have a higher gain than a high-frequency band, such as 1-18 MHz will have a high gain of about 20 dB and the gain will be reduced to around 14dB when using a 30MHz frequency.
