ANAN-7000DLE MKII vs ANAN-7000DLE.
What is the difference?
Thanks

If you are looking at the "no PC" version, there is almost no difference at all.

The cooling is supposed to be better in the MKII.

The MKII's also have a step attenuator after the DAC and therefore offer slightly better IMD performance.

Finally, there were versions of the MKII that offered an internal PC.

Both devices contain the same SDR board, both also have the 16bit DAC + step attenuator

Re: Warning for 7000DLE MKII owners

Just noticed a 7000DLE MkII that sold on qrz.com. It has a black face and ethernet port on the front panel. I have a 7000DLE MkII but it has a brushed aluminum face and the ethernet port is on the rear panel.
I did not know that there are 2 different versions of this radio. Does anyone know what else is different between these two versions beside front panel finish and location of ethernet port?

Tnx de Arnie W8DU

Arnie,

If you had looked at the Apache website, https://apache-labs.com/al-products/105 ... ition.html, you would see that Apache is claiming three "improvements":

1. Rugged Aluminium Extruded chassis for excellent thermal dissipation and Rx/Tx isolation.
2. PA board improvements for higher duty cycle, 100% ICAS duty cycle supported.
3. Tx Signal generation redesigned to improve SNR at low power levels.

The first two are primarily mechanical in nature.

The third one involves the placement of a step attenuator on the PA board that receives the signal from the DAC. This way the DAC can run at nearly maximum output all the time and only be adjusted over a range of +/-1dB, while the step attenuator does the heavy lifting of adjusting the gross drive level. All prior designs require the DAC output to be adjusted over the full range of drive levels.

However, that last change had been cut in during the production of the original version of 7000DLE MKII, so there is very little functional or performance difference between the black and silver versions.

73,

Scott
