Regarding: QST October 2015 Edition
Product: Apache Labs ANAN-100D
I take exception to your review in which you state that the Apache Labs ANAN series radio is based on the technology as the Flex Radio 6000 series.
I have no interest in FlexRadio System with the exception of being an end user of their technology; since the Flex-1000 days.
To compare an ANAN PDSR software radio to a Flex-6x00 SmartSDR radio is like comparing tube radio to a transistor radio.
To my understanding,PDSR development started under Flex radio CEO Gerald Youngblood K5SDR; your reviewed gives no credit to the developer.
Please let me quote from the Flex Forum: https://community.flexradio.com/flexradio
“The ANAN uses PowerSDR (TM - FlexRadio Systems). I personally started development of what later became PowerSDR in 1999. As a company FlexRadio invested for a dozen years in free development of PowerSDR which was later used by the open source community on the ANAN. Apache Labs has no internally paid software developers to my knowledge. It is all outside volunteer labor. We developed the diversity software used in the ANAN originally for the FLEX-5000 five or six years ago. The FLEX-6000 Series and SmartSDR is a long term and ever expanding platform.” K5SDR
Other things that was not broad out in your review:
“My biggest "gripe" with the Anan is the poor internal factory calibration. You need to use a calibrated signal source to calibrate the receive S meter. Also the transmit power calibration on the Anan is done at 100 watts. On some bands the power tracks sort of linear but on others such as 12 meters 100 watts is 89 watts out and when set to 10 watts I got 48 watts out!
The Flex on the other hand is factory calibrated and works fine right out of the box. Calibration is very linear right through the whole power range.” Dave wo2x
There were more complains about the ANAN radios that went un-noticed by you and others that reviewed your article before printing.
