Looking to upgrade from a Panasonic RF-3100. Just got off of an

considering a R-75 w/ DSP from Universal. Something that has always
been gnawing at me was the use of an HF transceiver for shortwaver
reception. There is routinely a large inventory of used HF receivers
available about my area; mostly HF nets/clubs and the like. Actual
HF/shortwave/comm's receivers are hard to come by here.

Are any of these used receivers notable in performance/feature set for
shortwave reception?

thanks

HF transceivers work fine for shortwave reception, and the older ones
typically may be just as cheap or cheaper than similar
receiver-only's. They do lack the sync detector, if that is important
to you. Also, make sure they have an AM filter of 6 khz or more for AM
listening -- a 2 or 3 khz SSB filter isn't wide enough for decent AM
sound fidelity.

Otherwise, for tabletop receivers, the Japan Radio Company models are
pretty damned good; I have a 525 that's held up well and has a good
feature set (altho' it lacks the sync detector).

If you can locate it, the book "More Radio Receiver -- Chance or
Choice" by Rainer Lichte, or his earlier book, "Radio Receiver --
Chance or Choice" are excellent references about receivers sold during
the last 40 years or so.

While it may not have a sync detector, the AM detector is a correct
implementation of ECSS. (No, I'm not talking about using SSB mode.)

One of my few complaints about the 525 receiver is distant AM signals
fade in and out, and I understand a sync detector will alleviate that.

My thanks to all for your comments. The HF transceiver path looked
better and better (not so much for AM Rx as DX seeking). In the
pursuit of this, a notice passed my way of someone selling a NRD-525
in excellent condition. Discussed this with the seller (an active
comm's hobbiest) and this led to my purchase of the unit. Look
forward to this long overdue, major upgrade.


Good choice. And I'm sure you'll find it a significant upgrade from
your Panasonic RF-3100. If you're looking to chase the weak DX, then a
JRC receiver is hard to beat.

I am VERY pleased with my 525. It is the flagship of my collection...

Put up a good antenna and you'll be all set. The 525 takes either a
high impedance wire or a 50 ohm coax feed; actually, you can attach
both and switch between the two. Good dx-ing...

Congratulations on the purchase. Let us know how you like NRD-525 and
what stations you pick up on it.

For One and All,

Any truth to the claim that the NRD-525
is a very good AM/MW DX Radio ?

I understand the stock audio is muffled somewhat.

For those interested, Kiwa offers an audio upgrade for the NRD-525:

The 525 audio supposedly has a little distortion, although it's never
bothered me.

The 525's stock filters are set at 6 khz and 3 khz. You can also
bypass the filters with the AUX switch, which gives about a 12 khz
bandwidth, and full-bodied audio for AM stations.

See if you can pick up Vietnam on your Shortwave Radio.Their music is
cool.I used to tote a shirtpocket AM transistor and listen to some
Vietnamese music in 1964 when I was in Vietnam.Or,you might find some
Vietnamese music on internet radio. www.radio-locator.com There is
a radio station (Cymru'r Byd) in Wales (Cardiff or Swansea) I sometimes
listen to.They play some nice music on the radio.I think from midnight
to about 6:00 AM or 7:00 AM their time zone,they are off the air.

I have been using my Yaesu FT-840 for over 7 years for SWL listening. I have added the 6 khz filter and also use it with an old Info-Tech 600 demodulator for SELCAL and RTTY. works great.
