Excellent Time Owned: 0 to 3 months.
I live in Cleveland, Ohio and WTAM 1100 AM can be trouble with harmonics and otherwise on HF. I bought this filter to do as reviews have stated and is doing it's job well. The product is made industrial proof. Thanks to Dale for your time in manufacturing a great product.

Solid Gold! Time Owned: 0 to 3 months.
Call sign is K4KPT. I live on the side of a hill which is great for radio. Unfortunately down in the valley below, there are two AM broadcast transmitters, one tower I can see from the back yard. This was not an issue until I started using an inexpensive SDR as a band scope in Linux. Did some research and the PAR product was preferred since its cut off would allow listening on 160 M with little or no loss. Most cut off at 2.3 MHz. Universal Radio had just sold their last one when I called. Called over to PAR Electronics and they were out too. Went ahead and ordered it. Well Dale did some magic and mine arrived 2 days later!

This filter is solid gold. If it works this well on a bottom end SDR, I can only imagine how well it would work on a better one. Build quality was just as described - very nice. Bottom line is, any receiver without dedicated band pass/front end filters like a TS-590, is going to need extra filtering being this close to AM B'cast transmitter.

Very Impressed Time Owned: 0 to 3 months.
I recently purchased the BCST-HPF filter to reduce some front end overload problems created by powerful AM stations in the Boston area. The result - stunning. The filter really brought the SDRplay RSP2pro rcvr to life while eliminatiing a lot of other noise. Great product!

Wow Time Owned: 3 to 6 months.
I have always been pleased with PAR products but this BC filter stands out and makes a big difference in a number of circumstances for me.

I find a very low insertion loss and appreciate the nice tiny package size. Portable radios with lesser front ends coupled to a sensitive antenna create overload and images when influenced by high power AM stations in metro areas.
This filter eliminates these issues and images for me even in presence of a flame thrower AM station.

With my SDR direct sampling receivers this can also make a difference in the overall noise floor if you are going for weak signals, I simply leave the filter in inline a large percentage of the time, even for weak DX.

I especially like the enable disable switch for instant comparisons. Well over 50Db reduction of AM powerhouse signals for me in most conditions,

Thank You for a find product Dale. I will be purchasing a second I like it so much.

BCST-LPF Used for DXing non-directional aeronautical beacons. Time Owned: 0 to 3 months.
Quick receipt of filter. Nicely packaged. Greatly reduces broadcast band QRN below 500 kHz. Has low insertion loss (0.11 db at 300 kHz. Nicely constructed and has bypass toggle. A nice feature for working higher frequencies. It's a keeper.

Exactly what was needed Time Owned: 0 to 3 months.
I noticed that I was having RFI issues with my SDRplay that I wasn't experiencing with my Icom R75. Local AM stations showing up where they should not be in the shortwave bands was my biggest complaint. Adding the PAR Electronics BCST-HPF to my set-up has removed those issues completely. Would not hesitate in recommending the HPF to anyone. Dale Parfitt makes an exceptional product.

Very happy customer Time Owned: 0 to 3 months.
I purchased one of Par Electronics AM broadcast high-pass filters in order to solve overload issues with my CommRadio CR-1. The CR-1 was suffering from broadcast overload in a bad way: I was hearing talk radio conversations on WWV at 5 and 10 MHz instead of the normal, soothing tick-tock that I expected.

The HPF arrived promptly arrived neatly packed in a small box. Fit and finish were excellent. The HPF is a small box, about the size of two packs of cigarettes machined of shiny aluminum. The model I ordered had two SO-239 connectors (Dale will ship you one with other connectors, such as BNC, if you order direct from him). There is a handy switch used to take the filter out of the circuit.

I installed the filter and tuned the CR-1 to WWL on 870 KHz, a 50 KW powerhouse that barges in on almost every other frequency I try to tune. Switching in the HPF brought the signal down from S9+50 to S9, a 50 dB improvement. Audio disappeared, as did the intermod that was making my radio unusable.

I can’t recommend this filter, or Dale, highly enough. If you have broadcast interference, or own a CR-1 radio, you should visit Dale’s site right away.

Excellent Equipment! Time Owned: 0 to 3 months.
I received the BCST-LPF in a timely manner. It is the Long-wave version of the BCB filter. I enjoy DX'ing and logging Non Directional Beacons from around 130 to 530KHz.

I have two broadcast stations near me, one to the east two miles away, and one to the south that just happens to be exactly two miles away. I hear both on the same frequency and can not hear anything else!

Testing on around 180KHz in the day time it cuts them completely out, which allows the very weak NDB's to be heard.
The real improvement is at night when propagation brings the weak ones in I've been missing.
The BCST-LPF is well made and the service from Dale at Par Electronics was excellent.

Wipes out BCB Overload Time Owned: 0 to 3 months.
Living in the LA basin, I thought I had to accept the front end overload and interference from the numerous broadcast stations, one as close as 5 miles from my home. However, using the BCST-HPF filter that problem is a thing of the past.

I do not have the test equipment to verify the specifications of this filter, but I will say this: I chose one of the stronger stations in the LA area, and engaged the filter, (it has a convenient activate / bypass switch) it was like I had disconnected the antenna. Gone, nada, nil.

Connected in-line with my beverage system, I'll never have to worry about BCB interference on "Top Band" again.

Thanks Dale for another fine product.

Zap that MW interference! Time Owned: 3 to 6 months.
After encountering occasional MW interference here in the S.W. USA, especially nighttime broadcasts from Mexican AM stations, I decided I needed a high-pass medium-wave filter for my old single-conversion Halli S-40. I thought about building one, but had no toroid forms around. Looking around, and seeing that PAR Electronics made one, I simply ordered a BCST-HPF from them, as I've had good experiences with their products and service.

The HP filter does exactly it says it will do and effectively blocks AM signals across a broad range of the SW bands. So far it's worked effectively down to about 2500 mhz, I haven't yet tested it any lower. It was especially useful on the 31, 41, and 49 meter bands. Uses a good metal housing with S0239 input/outputs and a useful bypass switch, and the toroids are nice quality. I even use it on my Kaito KA-2100 portable.

I would guess that most users of these filters are hams, but actually, any SWL'er with a portable who's added an external wire antenna w/coax feed and now finds AM interference and/or images all over his set ought to try this filter out. It will definitely zap that AM BCB interference, but good!
