Very Revealing  Time owned: 0 to 3 months
I purchased the Splatter View components. After careful adjustment of the oscilloscope and calibration; it showed me that I have been pushing the linear amp way beyond its capabilities of a nice fully modulated signal. Great for AM and SSB. The 'scope is the only way to REALLY see the absolute PEAK ENVELOPE POWER from the amp. And straight lines in the trapezoid trace. You must follow directions for connecting the units to your station.

IMHO "Required" for Station monitoring..  Time owned: 0 to 3 months
Recently I purchased two Tektronix scopes (2215A & 2213A) for my multi-station build.. Looking at what is available on the market and seeing that commercially built samplers were available, I contacted Tyler at CleanRF. After a short time and a very productive conversation I ordered the RF-S2K (2KW Variable RF Sampler & Demodulator system) which is now connected to my Tek 2215A.

I'm now able to see exactly what the signal quality was at position #1 with my IC-7600 and ACOM 600S Linear during transmission. I was able to see visually the PEP envelope and various wave forms of my signal.

After receiving the samplers a few days later, I was able for the first time to really see what my station was doing and they helped me identify some incorrect settings that required tweaking. The quality of my transmitted signal is far better now since the samplers were added.

The CleanRF system works.. Connected to your equipment then to your oscilloscope, it gives you a clear picture of what your station's transmitting and what the wave forms look like..

For my position #2, I've also recently purchased a RF-SM Station Monitor from Tyler so I could monitor my non-linear IC-7000 connected to my Tek 2213A. Again, I now have the ability to monitor my outgoing signal and both have helped me keep an active eye on my signals and equipment overall...

If you're considering using an oscilloscope to do serious monitoring of your station, then don't hesitate to contact Tyler at CleanRF Systems. The website is packed with information and the products are top notch.. Well worth the price and the piece of mind they bring.....

Feel free to check out my QRZ page and scroll down to see the units monitoring my equipment..

A "Must-Have"  Time owned: 0 to 3 months
Works great, just as advertised. I have the RF-AM1K model with the variable AM audio and RF out + scope trigger ports. Very professional workmanship. Using a splitter/combiner, I can send the sample RF out to my Tek scope, AND my Hammarlund HQ-170C receiver. The 170 has an RF control that lets me use it even with my 400 watt Swan 700 rigs. So I can not only SEE my SSB output, but I can HEAR it as well. Tyler mentioned that these units were not intended for that use, but I had to give it a try and it works! And of course the scope trigger and AM audio functions work perfectly also. I'm glad I bought one!

Model RF-S2K  Time owned: 0 to 3 months
Works as advertised. Had a problem with a cable on delivery and Tyler made it more than right, and quickly. He certainly stands behind his product.

Great product, well made, reasonably priced  Time owned: more than 12 months
As an amateur radio operator it is our duty to insure the transmitted signal is clean and pure. Initially I used both of the samplers (RF-S5K & RF-D) to provide Splatter View trapezoid monitoring using my oscilloscope. When I first installed the samplers and set my scope to provide the Splatter View, I was surprised how non linear I was operating using my standard tune up procedure. Using the Splatter View monitor it is very easy for me to insure the transmitted signal is pure and clean.

I have found two additional benefits using CleanRF products.

1) AM Audio Monitoring: The AM audio demodulator provides me with a quick easy read on my actual transmitted audio. I use the RF-Ds TRS audio out to drive my computer sound card / mixer. With a simple mouse click, I can monitor my AM transmitted audio in real time with a frequency response of 10 Hz to 16 kHz.
2) PureSignal IMD Reduction: I use the RF-S5Ks BNC output for Splatter View monitoring and to provide post amplifier RF sampling to my ANAN100 SDR transceiver. The RF sample is used by PureSignal IMD reduction software. PureSignal is a technology currently being used with the Apache Labs ANAN SDR transceivers and OpenHPSDR mRX to dramatically reduce IMD. Google PureSignal for more information.

Great product; well built and WORKS!  Time owned: 0 to 3 months
Great product. Works great and provides the best way to monitor your actual RF output. Giving several ways to view your signal and to detect any problems such as an over driven PA and IMD issues. Fantastic PEP power monitor. Perfect for all voice and digital modes. Would highly recommend this fine product to all hams. NOte: With older scopes such as the Tek 7603 you can get the best X Y display for a trapezooidial dispalyby removing the horizontal module and replaceing it with a vertical module. The RF goes to the V and audio to H.

Works well  Time owned: 0 to 3 months
An RF sampler is a must if you use an O-Scope, spectrum analyzer, frequency counter, etc. with high output signals. This one does the job and even has a variable output pot which is a bit unusual and rather helpful. I was pleasantly surprised to find that my order included cables as well as a coax adaptor. I was also impressed that before the product was shipped, I received an email inquiry about my intended use to assure the product would meet my needs. After I detailed my intended use, an additional output BNC fitting was added at no additional cost! What a quality company.

Model - Variable RF-SM  Time owned: 0 to 3 months
Love this product, best support from (Tyler)owner of the company. The product performed exactly as described. Would recommend this product and will purchase more equipment in the future.

RF-AM excellent product.  Time owned: 0 to 3 months
I held off purchasing one of these units for some time because of comments about the price. Should have bought it sooner! Great product and well worth the money for several reasons. First, with the external trigger out the scope no longer dances all over the place. Locks right on. The demodulated audio output to the headphones is first-rate. The unit is solidly built. Also, Tyler was very helpful and communicated promptly via phone and email. I would recommend CleanRF's products.

A Necessity for adjusting Modulation  Time owned: 0 to 3 months
Very well built and a nice addition to the shack. With a scope and the sampler inline you can monitor your modulation and adjust for clean transmissions.. As far as price is concerned, after spending money to setup a nice shack why would you skimp on (quality) test equipment that keeps your transmissions sounding great, and in speck.
