Great product, great service. Time Owned: 6 to 12 months.
From a Vendor's site:

"Our friend and colleague Neil Hecht passed away on August 19th, 2015. His family and AADE were his life. His wife and sons have our sincere condolences and best wishes. They ask for your patience while they determine the future of AADE." is currently down, and this is likely the reason. Hopefully arrangements will be made to continue the availability of Neil's outstanding lineup of ham accessories.

I ran the cables directly to the pins of the tubes.Ran the cables to the unit,powered up and had 21st technology in about 30 minutes.My Collins KWM-2 now tunes frequencies to +/- 10 hz.

On the Collins KWM-2 Time Owned: 0 to 3 months.
Unit works perfectly on the Collins KWM-2. If you use the tube covers, be sure to install the 3 jumpers inside the unit, otherwise it won't work.

I didn't care for running the RCA Jack cables from outside the KWM2 all the way to the tube cover circuit boards, so I installed two female RCA jacks on the back of the KWM2 and ran the cables to the rear of those jacks for the BFO and HFO functions.

There is still room for the K5GNA fan upgrade in the KWM-2, if you loosen the V-11 tube cover sheet metal screw and pivot the circuit board vertical instead of horizontal, the circuit board will fit between V16 and V15 allowing plenty of room for the fans.

I really wanted to do the direct wire to pins 9 of each tube in lieu of the tube covers, but didn't care for doing micro-surgery to the KWM-2.

There's no need to refer to the KWM-2 dial any more.

Stood behind the product Time Owned: 0 to 3 months.
Regarding a general purpose programmable DFD2 kit for dual conversion receiver.

- I was notified by Neil promptly after ordering that the kit shipped.
- The kit was received promptly
- The kit was missing several resistors and caps. After notifying Neil, replacements were received just 2 days later.
- My DFD2 would indicate LSB when should have been USB and vice-versa. This was not a defect of the DFD2 - rather the architecture of the RX I installed it in.

Neil then sent me a re-programmed PIC so that the DFD2 displayed sidebands correctly in my RX at NO CHARGE, again received 2 days after notifying him.

AADE's DFD2 product now does what it should and AADE supported me until it did.

Works Great!! Time Owned: 0 to 3 months.
Just bought the DFD2-520 LCD readout for my TS-520S via the AADE web site. WOW - great communications & super fast shipping. The unit brings my TS520S into modern times. Reads out down to 10 Hz. (ie... 3.870.00Mhz) - DEAD accurate too (I checked against my lab equipment)! Automatically reads the ENTIRE frequency (yes even the Mhz.) AND automatically reads out the mode. OUTSTANDING PRODUCT!!

On a Drake . . . Time Owned: more than 12 months.
I've used one of these on a Drake R4B for a few years now, and am very satisfied. Good product.

Excellent Time Owned: more than 12 months.
I have owned one for over 2 years and use it on my SB-102, and HW-101 Heathkits, and have installed them on other SB and HW series Heathkits. I cannot find any fault with them as if it was sold as a Heathkit for use with the series. I did use the SB-650 installation procedures with minor modification due to loading of the AADE to the HFO, BFO, and VFO. It is sure Great to have frequency readout to use with these rigs to use along with the analog dial. 73's N0CGF Dennis

Great value for money Time Owned: more than 12 months.
Neil's (AADE) Digital Frequency Displays combine ease of use with excellent quality parts and workmanship. Very well designed, stable and reliable, they provide efficient frequency measurement solutions for very little money.
