The sounds of distant stations from other 'countries' like Oregon, Idaho, and California was very exciting (at that time I didn't realise that there is a difference between countries and U.S. States -- I was very young at the time. In fact, the first time my parents took me to Oregon when I was 5 years old, I was expecting border customs!).
But I digress.
If you have read my previous MW DXing articles here on my blog, you already know I like to DX on the cheap!
I like to see what one can hear with a radio that is more or less consumer grade (as opposed to a Drake R8 or Icom R-75), with decent sound.
Although I use my GE Superadios and other DX portables a lot, I also use my Walkmen and DX-350's, usually with an external loop. DXing with such radios has a certain charm about it. I think it's the fuller sound you get through headphones. Then again, it's fun to DX on the cheap. And the fact that the Walkmen are so portable helps -- I also use them to listen to FM music in stereo, or AM sports talk, at work or when I'm out in the yard.
As most are probably aware, "Walkmen" radios / cassette players were a Sony invention in the late 1970's, and they became popular in the 80's when everybody had one. Sony wasn't the only manufacturer: nearly every popular Japanese and American radio maker had a "walkman" style player. I have an old Sanyo from the 1980's I got used at a thrift store years ago -- it has excellent FM and AM reception. AM is even DXable. I didn't get an actual Sony Walkman (with the actual "Walkman" logo on it) until I found that Goodwill thrift store -- which I previously mentioned -- several years ago.
The Sonys, however, work great.
I had previously bought a couple Sony headset radios new -- an SRF-59 and SRF-42 -- and I also have them pictured here, for reference, as they are better known. The SRF-59 is famous for AM and FM reception, and the Sony SRF-42 is well known as a good performer, and it also has AM Stereo, which is useless for stereo AM listening but useful for IDing stations on a crowded channel because the stations are in different places in the stereo spectrum.
This short article will concentrate on the three Walkmen I bought at Goodwill used: the Sony SRF-M78 Sports Walkman ($3 at Goodwill), the Sony WM-FX101 Walkman ($1 at Goodwill) and the Sony WM-FX241 Walkman ($2 at Goodwill).
All three of these are not 'DX machines', per se. But they are excellent performers considering the cost ($2-$3) and the fact that you couple them with a loop, you can hear DX on them quite well. Even without an external loop, you can hear DX stations and regional stations -- vital during emergencies.
Being able to hear regional AM radio stations is a good thing, especially during large emergencies, like a huge power outage or an earthquake. Walkman radios are vital for anyone's emergency kit, as most of them will bring in strong regional AM stations, when the local stations may not have power.
I'm sure similar radios to the one pictured in this blog post are still available at some thrift stores in the US and maybe overseas.
(I also found a Panasonic walkman and a GE walkman for sale at the thrift store. Both were good bargains -- the GE the better of those two. For the sake of simplicity, I'm concentrating more on the Sonys in this blog article.)
The Battery cover was also missing -- now it's Duct Tape. The radio is bright yellow like most 'sports' Walkmen, and it's water resistant, which means if you take it out in the rain it should still work without damage to the radio.
I don't know when it was first introduced. At first guess, I thought it came out during the 1990's some time, as it has the AM X-band on it (520-1700 khz on MW). According to the Sony manual, the SRF-M78 came out in 1996.
The SRF-M78 will DX reasonably well at night on the AM band -- I've taken it on night bike rides when I didn't have to worry about other traffic on the trail and have heard KFBK 1530 Sacramento with a readable signal. I also have heard KFBK at work in Seattle on this Sony.
The selectivity is decent enough that you can hear adjacent channel DX stations with a certain amount of splatter.
There is only bleedover on the strongest locals -- on a couple 50 KW stations and a closer 1 KW station. I'm guessing the reception is a bit similar to the SRF-M37W that a lot of MW DXers talk about online -- perhaps a bit less.
Where the SRF-M78 falters is above 1600 khz. Although the radio has the Top Band (or "X-band"), performance isn't good. It's almost like it was an afterthought. Even with an external loop it isn't that great on the X-band.
The Sony SRF-M78 has five presets on each band, AM and FM. They are very easy to program. Use the up or down tuning button, and tune in your station. Then press the 'Enter/Clock' button, then press the preset button where you want to store the station, and hold it until it beeps. That's it.
I use my Sony Sports Walkman sometimes while working in the yard, and sometimes while biking -- either at night, or on the local Trail. I keep the volume down while on my bike, and listen to AM only. Stereo FM seems to interfere with hearing nearby traffic and I want to stay safe. AM, being in mono only, doesn't limit what I hear that much.
Some online reviews mention that the volume control moves around on its own through contact with the armband. I haven't had that problem at all. Maybe the online reviewer was wearing the radio upside down.
This black Walkman is probably the best overall performer of my AM-FM-cassette Sony Walkmen.
You add a loop and it works very well. The selectivity is wide enough that the fidelity is terrific -- listen to an NFL football game you almost think you are there. There is more splatter on this radio than you'll get on the famous SRF-59 -- but you can add to the selectivity by moving this Walkman away from the loop. I heard maybe 15-20 new stations on this radio when I was DXing with it in 2012-13.
Unlike the SRF-M78, the WM-FX101 works well on the X-band.
But you won't get a ton of DX on it up there without a loop. I was able to receive a very weak XEPE 1700 (in Tecate, Mexico) the other night, and 1640 KDZR from Portland (200 km away) comes in without a loop when conditions are fair to good.
But overall on the X-band, signals are just mostly too weak to get readable DX, as they can be on any portable AM radio.
Compared to the famous Sony SRF-59, this Walkman is slightly less sensitive, but it will hear every station my SRF-59 hears -- just at slightly reduced quality. The selectivity is a bit wider, and the AGC isn't as tight, which is refreshing as the SRF-59's AGC is very tight. Overall, the sound of the WM-FX101 makes for a more pleasant listening experience while monitoring or DXing.
I'm certain all of these thrift-store Sony radios have the same Sony CXA1019 chip, which is a hot chip, and was very popular in Sony Walkmen and Dream Machine clock radios during the 1990's and 2000's. The main reducing factor in these Walkmen for AM reception is the loopstick antenna. I haven't been able to get any of these apart yet to see what the inside looks like. I'm guessing the loopsticks are equally small on all of these radios. But considering they are small, they have decent reception.
It works surprisingly well on the AM band, considering it's just a Walkman. It doesn't perform up to SRF-59 standards, but it is still a decent listening radio. Its X-band performance is as good as the rest of the AM band. It's slightly less sensitive than the analog tuned WM-FX101.
It has 40 presets -- I haven't used them all. There are 30 memory presets for FM, and 10 for AM. I have maybe 8 of the FM presets used -- all three rock stations I listen to (KVRQ, KFOO, and KISW) and the three pop stations in Seattle (KBKS, KPWR and KQMV), a news station and an NPR station. From the factory the presets are already set to various spots on the dial, which could be handy if you don't fill them all -- it would be sort of like jumping randomly to another part of the band.
The memories are easy to program: you press the "Enter" button once, scroll up and down the memory locations using the + or - key (plus or minus "Preset" keys, big grey ones just below the readout), and press the "Enter" key again.
The WM-FX241 will DX with an external loop, even on the X-band. It's slightly weaker than the FX101 on the X-band without the external loop, but it's miles better than the SRF-M78.
Compared to the WM-FX241, the earlier model WM-FX101 seems a bit more sensitive, and it has tighter AGC. But the WM-FX241 seems to have more usable selectivity. It's a toss up between the two. Both work well with my loops. Of course, the digital tuning on the 241 is handier to use.
Unfortunately, this radio doesn't have a way to adjust the MW channel step from 10 khz to 9 khz steps, or vice versa. If there is a method, it's either not documented or I just haven't been able to find the button sequence. For most Walkman users, this wouldn't be an issue. If you're traveling overseas a lot, you probably already have a radio capable of MW 10khz / 9 khz channel steps.
The WM-FX241's sound -- like the other two used Walkmen -- is excellent. This means it undoubtedly has a single ceramic filter, which is adequate for MW DXing if you pull the Walkman away from the loop a bit, but it also sounds good. And with a little wider response, it's easier to catch ID's. On FM, it sounds better than the SRF-M78, and a little clearer on fringe FM stations than the WM-FX101.
This radio has "mega bass", which scoops the sound on both FM and AM and is like a loudness boost. I haven't found it useful with regular Sony headphones, but I have a cheap pair of earbuds that are a bit on the thin side, sound-wise. The WM-FX241's "Mega-bass" button makes them sound better.
Online I've read mixed reviews about all three of these radios on their indoor FM reception. The problem seems to be when the user is inside a gym or an office building, and the headphone cable acting as an antenna can apparently alter FM reception if you move around. I haven't had any such problem, but most of my listening on these radios has been at home, at work, or outside.
I did a quick FM test using all three of these thrift store Walkmen. I used KFOO Tacoma, 102.9 Mhz (classic and alternative rock) as a target station, as it is a 'fringe' station here and some of my radios bring it in only in mono. Some of the cheaper clock radios don't bring it in at all.
The WM-FX241 had the edge in overall FM performance. It brought in 102.9 in clear stereo with slight fuzziness depending on how the headset cable was moved. But it was the best overall. The SRF-M78 brought it in in mono only, and a bit dicey at times. The WM-FX101 brought 102.9 in stereo, roughly equal to the 241. It took a bit to center it using the analog tuning. Like with the other two Walkmen, moving the headset cable altered the reception a bit, but both the 101 and 241 kept KFOO in stereo.
On a stronger station, 98.9 KVRQ (the rock station I wrote about several blog posts ago), the SRF-M78 has a bit wider stereo than the other two radios, with the WM-FX241 having a bit tighter bass response.
None of these three Walkmen are probably FM-DXer's, which is no big deal to me as I don't DX the FM band. The best sounding FM Walkman I have is the digitally tuned WM-FX241.
When the big one hits, we'll be on our own for a while. And in Seattle it's not just one 'big one' we need to worry about, it's both big ones: Seattle has its own fault which bisects the city, and it is supposedly set to go off sometime soon; and the Cascadia / Juan De Fuca subduction zone which is off the BC-Washington-Oregon coast is also set to go off any time now.
This is one reason the US government is concerned about AM radio's survival. In a severe emergency (like a Cascadia Earthquake), AM radio is one of the most dependable regional emergency broadcast tools.
This isn't just the opinion of a long distance AM radio aficionado. A recent Oregon and Washington government document called "Cascadia Rising" concluded that in event of a Cascadia Earthquake, AM radio may be the only emergency broadcast media available to hard hit Coastal and other areas:
"With AM radio's longer broadcast range, survivors with power, or those who attempt to listen in their vehicles, may be able to receive AM radio signals."
I'm sure some newer, off-brand headset radios work O.K. But not all are good for DXing or emergency situations. Of the newer headset and small, personal portables available, Sony and Sangean seem to offer the best quality for radios that are readily available today. In my view, you can't lose with a Sony or a Sangean.
Add a loop -- you're in business for MW DXing. And you can't beat the price -- either for a cheap DX radio, or for a preparedness radio you can sock away in an out-of-the-way, safe place with a couple spare sets of AA's or AAA's. Used Walkmen radios can't be beat for that!
