"We bought a duplexer DPRE4-6-2m (low temperature drift) from IK- Telecom for our local 2m hamradio repeater which is mandatory also in an emergency situation for our region.
IK offered us fabric tuning to desire frequency free of charge. Everything was ready very quickly including fine tuning and delivery to our address.
All progress was updated on almost daily communication.
Duplexer has a nice design, performances and is not heavy and easy to transport to mountains too.
We highly recommend duplexer from IK-Telecom for hamradio and profi communication."

"Hello,
here is a picture of the diplexer during installation this afternoon.
Then we test it with a QSO (communication) on the UHF band and another on the VHF band. No issue on any band ! 👌🙏 bravo 👏 ! Fine business as we say usually !
Thanks for your great product quality !"

"Hi,
The filter has been in use for 2 days now and the difference
is noticeable.
Maritime mobile with 5w noise-free over the repeater, the repeater itself was end of the scale there.
There are places where they also get noise-free over the repeater with the walkie-talkie.
The purchase was certainly not a bad buy, good work done guys !
The power that i am using to the filter is the same as before, 40w.
Oh , and the maritime mobile was 70km away ."

Success stories:
Duplexer received today and I have to say it was very well packed. It's now installed on the repeater and is a huge improvement on what we had before, so very pleased with it. Take a look at gb3rw.uk for photos of it in use.

Tuesday, i have well received the duplexer on 145.600 MHz. I have measured the parameters and found an insertion loss in the two ways of about 1.3 dB. The Duplexer is installed on the repeater of the region of ‘La Louvière’ 50 Km south of Brussels and 30 Km North of the France border. It works very well. The repeater ON0LLV works with a duplexer DPRE4-6UL (round), bought to LAM-communication at the rally of Rosmalen in Nederland many years ago. Thanks for your actions to fix the problems. The radioclub of la Louvière organize the biggest rally of Belgium and France end of September (Sunday 29th in 2013). More then 2300 visitors that come from Belgium but also a lot of France. I your company, LAM communication or other company want to come in our rally, it’s with pleasure that I give a free place and a low price hostelling. Best regards

I have recently purchased and installed a DPRV4-6 S/no.390720 for a new repeater system to replace an existing system which is 30 plus years old and not operationally satisfactory.
The duplexer is beautifully constructed and operation is 100%.I installed it in a new QTH for the Inverness Repeater group (BIRG) atop an 18 meter tower located 393 metre above sea level, results are fantastic albeit a 15Watt drop through the duplexer. Radiation from the antenna is 25 Watts fed from a Hytera RD985 via the duplexer.
Grid locator is IO77RM.
Congratulations on manufacturing an excellent piece of equipment.
Regards, Ken MM0GKB
