Great Service - Outstanding Product, None Better !  Time owned: 6 to 12 months
I called PAR filters expecting to leave a message, but to my surprise Dale picked up the phone. I have 3 high powered FM stations that was causing all my Wideband Receivers to overload in the Air Band and 2 Meter frequencies, causing intermod, and a rise in the noise floor of my radios. Dale was able to make a custom filter to NOTCH the 3 FM stations that were causing all the problems. As soon as I attached the filter to my radio, the noise floor dramatically dropped on the Air Band and 2 Meters. Sensitivity was outstanding. This filter gave me the hobby back for these bands. I cannot thank Dale enough. I learned a lot just in a 10 minute conversation. Price was very reasonable, and the filter was on it's way to me in 24 hours. It does not get any better.

VHF SYM-162HT  Time owned: 0 to 3 months
Added another PAR Electronics filter to the collection.

I've been traveling a route lately that is rich in NWS transmitters...good for weather notifications, bad for scanners. I got to try the filter out this past week and it's completely resolved all my phantom NWS signals in the VHF band (mixed in with pagers, DMR and all sorts of other things at times).

I also swept it and the sweep almost perfectly matches the sweep supplied with the unit.

And a thanks to Dale as I ordered this right before Christmas and he was able to build it, send it out and have it arrive in exactly 1 week. And he kept me updated via email as well.

Can Hear Again!  Time owned: 0 to 3 months
The VHF Symmetrical Intermod Filter is an excellent
way to regain the use of spectrum otherwise blocked by excessively strong paging transmitters. Mine is tuned to 152.8 MHz, and does a fine job. There is absolutely no sign of the offending signals on the two meter band now. Highly recommended for those of us afflicted by this situation.

VHF High Pass Filter  Time owned: 0 to 3 months
I was having trouble with my 2 meter radio overloading the receiver on my TV. I called Dale who took the time to explain why my situation was causing this and what could be done. As a new ham this was tremendously helpful! He designed a filter for me and between utilizing it and his other suggestions my problem is gone! He is a great guy and will work with you to solve your problem! I highly recommend him!

Awsome Experience!  Time owned: 0 to 3 months
I called PAR looking to purchase an FM Notch Filter, Dale was so kind, he assisted me in ordering a custom made FM notch for the frequencies that were the most trouble. The service and attention to detail are second to none. I would without a doubt suggest contacting PAR for all your needs, a great group to deal with. Dale was out of town and still communicated with me to ensure I received what I was looking for, it just doesn't get any better than that.

Thank you Dale for a great product as well as your attention to your customers!

Worth EVERY penny!  Time owned: 0 to 3 months
About five minutes into VHFSYM152HT post-install monitoring, I knew the money I sent Dale was well spent. My filter is placed on the input side of a Stridsberg MCA204M multicoupler sharing a Comet GP-15 antenna that is exclusively used for receive only in the VHF and UHF public safety ranges. Suffice to say this filter is kicking the offending paging system's butt! I was getting killed by a strong paging system on 152.600 which was mixing with a local NOAA weather broadcast at 162.550 and dumping out in the 165-170 MHz range on my Uniden BCD996XT. I enjoy unattended searching, logging, and audio recording using ProScan software in that band for signals and prior to this filter it was nearly impossible to do so. Problem solved! Also, looking at the signal via my Airspy SDR it is clearly significantly attenuated, no more images and aliases from it showing up on screen. Without the filter the signal peaked right at around 0 db, with the filter inline it was knocked down to the area of -40 db as advertised, and any aliases or images from it that appeared all over the FFT were gone.

I'm not sure what delayed me in buying one of these gems, but I am certainly glad I did. As mentioned elsewhere in these reviews, communication with Dale is a pleasure; questions are promptly answered in a knowledgeable and friendly manner. I have bought other items from Dale in the past and this customer friendly approach is always consistent.

I'm extremely pleased and I would not hesitate to recommend this filter to anyone having a similar problem. Talk about $$ well spent!

Product works great and good customer service  Time owned: 0 to 3 months
The purchase of a VHFSYM162HT scanner filter was well worth the money. I live close to a NWS tower and my regency scanner was useless from 151Mhz to 160Mhz with 162.55Mhz on every frequency. The VHFSYM162HT filter works great!!! A 134.25 frequency was overloading my bearcat scanners and the image was on 155.85Mhz. I ordered a custom filter notched at 134.25Mhz and once again the product worked very well!!! Dale makes a high quality product that works and customer service is A+++.

Absolutely stunning product and customer service  Time owned: 0 to 3 months
My review follows the many written before it.

Almost instantaneous email response, with an almost as quick diagnosis. We quickly determined that an existing Par filter design could be easily tweaked and fit my requirements.

I have a mobile digital scanner in my vehicle. Whenever I transmit on an adjacent VHF ham radio, it completely wipes out not only the VHF public safety stuff, but also the 800mhz digital traffic.

Par built me up a filter with the specific connectors I needed and shipped it out in a couple days.

I just got the filter and WOW!! What an excellent product. It comes in a well built enclosure perfect for the mobile environment.

I can now use the ham rig while using the scanner.

Excellent service and product.

152mhz and 158mhz  Time owned: 0 to 3 months
Great Job over there at Par. My intermod is gone from 152.48mhz and 157.74 MHz perfect tuning and im able to receive in the 151-152 range and 153-156.5 range where I had nothing but intermod pager sounds.. Par tuned these right on the money...
I highly recommend both the VHFSYM152HT AND THE VHFSYM158HT... these have cut out 2 of my 3 offending frequencies completely... I will be buying their FM trap to kill out a local fm broadcast station for npr in the very near future.
Thanks also for the 20 or so emails back and forth with all the help.. Will recommend...

PAR SCANNER INTERMOD FILTER  Time owned: 0 to 3 months
After years of inactivity, I decided to dust off a couple old scanners, and plug them in. Not finding a lot of clear activity, I installed a Diamond Discone Antenna atop a pushup pole ( put it about 35 feet up); only to discover that my ole scanner was picking up a NOAA weather broadcast that is transmitting just a mile or so from me on almost every frequency I programmed. In attempting to determine the reason for this I turned to the internet.

It was within that research that I found and the positive reviews on Dale Parfitt and his company, Par Electronics. Hoping Id correctly identified my problem, I sent them and e-mail explaining it; to which I got a very prompt and polite reply indicating they could build a SCANNER INTERMOD FILTER that would likely remedy my problem. I ordered said filter, and within a few days received a very well built filter, that instantly solved my issue! I highly recommend this company and their products, and will certainly keep them in mind for any amateur radio/scanner needs in the future!
