Allow me add my name the list of people thanking you for VK2US-1.
Thank you.<br>
<br>
With regard to the capability of the FM828, I'm sure many of you
have seen me recommend the humble FM828 on many occasions, and
with good reason. The radio might require a pair of decent
crystals at a cost of about $70 but you can get the radio for
free, or maybe $20. For less than $100 you have a radio that is
almost bullet proof. <br>
<br>
The FM828 rx has a respectably narrow front-end that was never
intended to extract the last 0.1uV from the ether. It will do,
typically, 0.3uV for 12dB SINAD (the spec says 0.35uV for 12dB
SINAD), however, and return that performance under very hostile
circumstances. Ask yourself if you want a 0.1uV rx that clams up
to maybe many uV (or blocks completely) under harsh conditions, or
a rx that hears 0.3uV 24/7. Standing current of the 828 is also
respectably low, around 250mA when muted. If you take low level
audio and keep the volume control wound right back the standing
current doesn't change when a signal is received. The FM828 tx is
continuously rated at full power (25W) and the unit will work over
the range 10-16v. Try that with your Yaecomwood! <br>
<br>
The rx in the Philips FM814 base station is directly from the
FM828 mobile. Yep, Philips engineered a damn good radio with the
FM828 and, that was around 1978.<br>

<div>Thank you for hosting the digi for the last 10+ years - it
has been fundamental to the APRS network in Sydney - in fact a
large chunk of NSW! For those that are unaware, the coverage of
this digi is/was phenomenal with direct paths out to Orange,
Canberra and along the coast to Newcastle and beyond Wollongong.</div>
<div><br>
</div>
<div>As one of the installers of this digi I'm still blown away by
how well a humble FM828A mobile rig with no external filters
handled the intense RF environment of the CBD, being a stone's
throw from GPT and Centerpoint - the two largest comms sites
bristling with pagers.</div>
<div>The original installation was an FM92, however the high noise
floor rendered the digi useless, it couldn't hear anything
beyond about 5km from the site - swapped with the 828 and never
looked back.</div>
<div><br>
</div>
<div>It will be sad to see this digi close, but, life goes on :-).</div>
