Perfect for changing conditions!

Time owned: 3 to 6 months

The mistake I made.... I should have ordered the parts to allow monitoring two antenna feeds (both transmit antennas for my K3). I'll be adding the kit soon, and rest a little easier.
As a believer in resonate antennas, and not using "antenna tuners" and cumbersome matching devices that I'd have to keep an eye on... This little bugger squeals like a stuck pig if my SWR goes out of whack (if I want it to, which I set for 2:1 SWR). I don't know if the RAIN is affecting my antennas, if my big verticals fall over, or squirrel downs one of my horizontals... but it gives me instant visual/audible warning something is amiss!
Rather than keep hitting the "TUNE" button on the radio, and assume everything's OK - when the weather's not, I can get a good ACCURATE visual picture of what's going on, without flipping dials, turning knobs and staring at a skinny little moving needle (it also shows PEAKS).
While is looks like a luxury addition to a shack, my LP-100 is right there, giving me really fast feedback on my Linear's performance. Kinda like a computer or cell phone - once you have one, you can't imagine ever being without one.
We bought it as a kit.... my KIDS put it together. I sent it to Larry to calibrate (Monday), and much to my surprise - he had it back to me on Thursday ... the same week..!
WOW! Yeah, it's worth the extra $ for something that works seamless with any radio.

Outstanding product

I am very pleased with the LP 100A and the fantastic support, with any question I found Larry to get back to me in a very prompt fashion. I ordered the LP 100A as a kit and the manual was very straight forward and easy to understand. The illustrations were very well done I was also pleased to find out that for the final calibration I could send it down to Larry and have him take care of it. I wanted to have a good SWR and watt meter and with the LP 100A I got an outstanding one. This meter does a whole lot more to which I have to learn and take advantage of. Fantastic product Larry and excellent support.

Work of art

Larry has done a tremendous service to the amateur community by building this product. After researching 3 different similar products all with in $10 of the same price the LP-100a won hands down. Larry is a pleasure to work with and surely doesn't mind answering emails on Christmas eve.
A very fine Watt metter, SWR meter, antenna analyser, etc. Can't wait to what's next.

Versatile and Outstanding
|

This instrument is pretty unique in the market, with lab grade precision, and vector readings in addition to the usual reflected power and SWR displays. The bar graph displays react much faster than any analogue meter could, and a real time peak reading gives you a pretty good indication how "stiff" your power supply is. Combine this with the protection against high SWR for your amplifier, and this device, even though it's not inexpensive, may pay for itself. It certainly is worth every penny.

No Nonsense Meter
|
Time owned: 0 to 3 months

I like most have had the usual watt and SWR meters built by MFJ, Drake etc... Well this is surely nothing like you have ever used before. The accuracy of this meter is unbelievable. It is extremely easy to use and quite a good looking meter as well. Aesthetics play a big role for me in addition to function. This meter has it all, It is very sharp looking and works very well. I received the meter from Larry programmed already with my call sign which i thought was just a little bit of attention to small details. He could have just shipped it but he added my call which to me also shows he turned it on to verify it worked before shipping.
I am very happy with my decision to go with the LP vs the other meters simply because the features and adaptability this meter offered vs some of the others. I recently had an issue and called Larry because I thought it might have been the meter. Well it turns out it was not which was a relief to me but Larry really assisted me in testing the problem and continued to work with me even after finding out the meter was not the problem. He did not jump ship when he realized his product was not the issue he continued to assist. Anyhow, I am very happy with my decision. The product and customer service are Bar None.

Excellant Shack Accessory
|
Time owned: 6 to 12 months

I use the LP100A RF watt meter every time I tune up the rig. It is infinitely more accurate than any other single or dual meter analog SWR bridge. It allows me to adjust my antenna tuner to a nearly perfect 1.0:1 match every time. I highly recommend this product as a valuable addition to any ham shack. Be sure to have good quality dummy loads on hand to perform accurate calibrations after construction. (Or send it to the manufacturer for free calibration.) A free Windows application download allows a display on your computer monitor.

Outstanding and Versitile
|

I put off buying one of these since I already had an AIM4170 for impedance measurements, but I'm glad I finally bought one. I built the kit version and have two remote sensors, both the "standard" HF 3KW units. There are several optional sensors available. It is a fairly quick build, but probably not best for the beginning builder. Instructions are complete and clear with lots of photos. I did my own calibration since I had some standards for comparison. The calibration process is fairly long and detailed, but if you take it one step at a time and pay attention you will be rewarded with an amazingly accurate meter. Both of my sensors, the AIM 4170 and a power standard all agree within 3% over the complete HF frequency range. SWR accuracy is similar. Larry offers a free calibration service also.
This is a nice looking and nifty unit to use. I run two different antennas on the two output ports on the K3, and the auto-sensing feature with two sensors gives me a constant readout of SWR and power as I switch between the antennas. Crisp, legible display. The direct power measurement mode is slick and quite handy around the shack for measurement of power levels in dbm. For example, I used it recently to quantify the power being dumped into my K9AY RX antenna on various bands from my Xmit antennas.
You won't go wrong with this one - highly recommended!

The best of all - bar none! I have 3 units now!
|
Time owned: more than 12 months

I got all my LP-100(A)s as kits but Telepost offeres factory build and calibrated units as well! The kit is of very high quality and a fun project to build.
The resulting meter is an accurate and feature packed lab grade instrument! I had an Array Solutions Powermaster which was OK but not nearly feature rich as LP-100 so I sold it. The LP-100A is not a simople Wattmeter - it goes beyond what one would expect from a digital wattmeter - it shows complex impedans, R,X and Phase Angle, compression, etc. It has a very high level of customizations and ergonomics features. The meter can be used in dual coupler configuration 1 control head, 2 power sensors. Larry, N8LP offers absolutely excellent cutsommer support. I have not touched my Bird 43 since I started using the LP-100s. My two newer units are LP-100A - Larry is constantly working on the firmware and software (yes, it has a virtual control panel via RS232 interface)

Best power & SWR meter ever!
|
Time owned: 0 to 3 months

This unit put all other Power & SWR meters in the scrap bin.
I highly reccomend this equipment to all of us.
And as W6VZV said in an earlier statement. N8LP/Telepost had programmed my callsign into the screensaver as a nice little courtesy.

It's a superbly designed and outfitted kit. Excellent quality and design throughout. It does everything it is advertised to do. I will be taking Telepost, Inc up on their offer of free calibration.
The building time of 8 hours is probably a bit aggressive. I have about 11 hours into mine and I took the time to double check everything. I could probably build a second one in 8 hours.
This makes all other consumer level power and SWR meters obsolete.
