***SOLD*** CleanRF Systems Splatter View

***SOLD***More shack cleaning! I have a CleanRF Systems' Splatter View 2K for sale. The Splatter View samples RF at the input and output of your legal limit amp and allows quick and easy determination of your amp's linearity - don't we wish everybody used one of these? This consists of two separate units (about 3" x 2" x 2") and functions as the old "station monitors" did. Used with your oscilloscope, you can check amp linearity with the traditional trapezoidal scope pattern, and more. My units are pristine and from a non-smoking environment.

See www.cleanRF.com (my version is the RF-D and the RF-S2K RF samplers - OK to 2,000 Watts) and read what the three eHam reviewers said about it:

*** 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.

*** The CleanRF RF Demodulators and RF Samplers work as advertized and are an excellent value for anyone needing precise monitoring of their RF envelope or amplifier linearity.
While the inside components are basic, they are high quality and are the exact values needed to properly calibrate for the power being used.
Yes, you could build your own RF sampler or RF demodulator and save a few bucks, but for those who want to just plug and play, these units are very simple to install. By time you purchased all of the parts (case, components, cables, and adapters needed), the time and cost to build one yourself starts to add up.
I have owned my "Splatter View" for over two years, trouble free, and have found it an indispensible part of my RF monitoring, knowing what's going on at every instant.
As far as I'm concerned, every serious ham should have the ability to properly monitor their RF signals, and these units make it simple to do so when used in conjunction with a good oscilloscope.

*** Any amp, if not adjusted properly, can be capable of casuing splatter. The Splatter View enables you to adjust your amplifier so that it is in fact linear. The Splatter View consists of two boxes. The coax from your rig goes to one box and from there goes to your amp imput. The output of your amp goes to the other box, and from there goes to your antenna or antenna tuner. The output of each box goes to scope input. Splatter View makes it ultra-easy to peak your amp and at the same time maintain a perfect trapezoid pattern. The reason I give it a 5 is that it works perfectly, is a no-brainer to install, and absolutely guarantees that you are able to operate knowing that you are not splattering. The units are of highest quality construction and work easily as advertised. I know of nothing comparable on the market at this time.

Reason for sale: Because of using the Splatter View system, I now know exactly how to to set my amp for linearity, and this system is surplus to my needs at this time. The package consists of the RF-D and RF-S2K RF samplers, two 6' BNC-BNC cable (each unit connects to your scope), documentation and other notes from my file. I paid $215 for it in 2013 and am pricing it to sell at $100 + shipping from Southern CA. PayPal or personal check OK.
