Not a fan of that case style, but wonder what they did to get to these 2 listed improvements:

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.

I don't like the larger size either, but I suppose anything that assists with heat management is good. I've been playing a "shell game" on my desktop, trying to figure out placement that works while not disrupting present operating ergonomics.

Concerning points 2 & 3, see Ahbi's reply from the Apache mail list:

"So far as the improvements in the hardware are concerned:

"1. Bigger heatsink
2. Changed components of the PA LPF and SWR bridge for higher duty cycle, ie the radio is more rugged now.
3. The Tx chain now controls power using a digital step attenuator and the DAC is now always driven 100%, this results in higher SNR at low power levels."

Take a look at the Apache Labs website this morning.
The old style 7000DLE is no longer in the product lineup.
It was still there as late as Saturday, when I last looked.

Wonder if there is a mod path to update older boards, or is it not significant enough? I only run my 7000 @ 30W to drive my amp anyways.

Hopefully there will be PIN diode switching available in the next future..... 8-)

The PIN diode T/R switching circuit is easily implemented. However, to do it right means upconverting +12V DC to over 100V so the receive PIN diodes can be reverse-biased during transmit. Otherwise, a high SWR at the RF output port (e.g., accidental open or short) will cause the receive PINs to conduct during transmit, therby exposing the front-end to transnit power. High speed SWR circuits together with an incandescent lamp on the Rx input can help but it's no substitute for high reverse bias V on the Rx diodes.

Bottom line: it's not as easy as replacing a relay with a handful of PIN diodes and chokes.

Abhi, I have been trying to but a 7000 MK2 with the free shipping offer but the shipping charge still appears in the cart . I've emailed support but no reply so far.
