[TenTec] Reasons to buy an OM7 instead of an Eagle

Well Rick as you know, I have both on the desk.

The Eagle receiver is somewhat better.  How much well with the optional 
filters in the Omni VII and both used for CW, I perceive one would find it 
necessary to have both radios and the ability to switch between the two to 
discern much if any difference.  Sherwood Engineering has the Eagle Dynamic 
range Narrow spaced measured at 90 dB while the Omni VII is measured at 80 
dB.  Rob also stated that most hams will find the 80 dB performance most 
adequate.

However, per Sherwood Engineering Receiver report, the Noise floor on the 
Omni VII is -130 & -140 dBm while the noise floor on the Eagle is -124 
& -132 dBm.

The display on the Omni VII is much easier to see and read plus it gives 
more information and one can see the S meter  {Rick}.

The S meter on the Omni VII goes to 60 dB over S-9 while the S meter on the 
Eagle goes to 30 dB over S-9.

The S meter on the Eagle shows only signal strength and SWR.  The S meter on 
the Omni VII shows signal strength and is user selectable between PWR out 
and SWR.

The Eagle has dual concentric knobs for AF gain and RF gain and another set 
for PBT and BW.  The Omni VII has one knob that has a momentary push in to 
toggle between the two functions.

The Omni VII had separate RIT and XIT buttons and displays. The Eagle had 
only a RIT function which is difficult to read the value on the display.

The Omni VII has a CW spot function.  The Eagle does not.

The Eagle has a hardware Noise Blanker.   The Omni VII has a firmware Noise 
Blanker.

The Eagle DSP BW works nicely down to 100 Hz while the Omni VII DSP BW only 
goes to 200 Hz.  For both radios, any optional filters automatically switch 
in the RX path as the respective BW is selected.

The Omni VII RX BW is adjustable up to 12 KHz standard.  The Eagle BW 
adjustable up to the widest roofing filter installed.

The MENU on the Omni  VII is accessed by a MENU button on the front panel. 
The Eagle Config Menu must start with the power off, hold down FNC and then 
turn power on.

The KEY jack on the Omni VII is on the front and is a 1/4" TRS connector. 
The KEY jack on the Eagle is on the rear and is a 1/8" TRS connector.

The EXT SPKR jack on the Omni VII is on the rear and is a 1/4" TR connector. 
The EXT SPKR jack on the Eagle is on the rear and is a 1/8" T R connector.

The Omni  VII has a dedicated button for TUNE and PWR while the Eagle one 
must use the FNC before accessing the PWR function.

The Eagle is controlled externally via USB communications port.  The Omni 
VII is controlled externally by a RS-232 port.

The Omni VII has a direct internet connection.  The Eagle does not offer 
this feature.

The Omni VII offers two ANT port plus a separate RX ANT port.  The Eagle 
only offers a single ANT port.

The Omni VII offers direct frequency entry.  The Eagle does not have direct 
frequency entry.

The Omni VII can switch direct to any band with the push of a button.  The 
Eagle must cycle through several bands to get to the others.

The ATU is much faster to resolve a match with the Omni VII.  The Eagle 
takes a bit longer to resolve a match. Both radios ATU will match a 10:1 SWR 
or better.

The Eagle is about 1/4 the size of the Omni VII




I could do three or four  pages of this stuff.  How much more do you want or 
need?    Best bet, just download both manuals from the Tentec website and 
read them.
