Hello Matt. Great video showing the internal filters. I was reading a receiver review from N9EWO on the NRD. He mentioned that a Surplus Sales of Nebraska concern occasionally has filters. Good hunting with Great audio! Randy-Illinois
It's a communications receiver, and was really never targeted at people that wanted to listen to broadcasts - IMO, if you want to do that, the 525 is a much better fit. The fact that you can get options like a RTTY decoder, VBT and ISB operation for this radio makes it really clear who the actual target market was. The 535 I have was sold as surplus by the Japanese embassy, so I guess we can work out at least one group of people that were using it.
