<p>Dear colleagues,</p>
<p>This is the sky frequency coverage for the IRAM 30M 3mm Receiver:</p>
<p>LSB (73 - 97) GHz</p>
<p>USB(89 - 117)GHz</p>
<p>These numbers are the center of the 4GHz IF bands, so the real
most outer limits in sky are +-2 GHz (71 - 99)LSB and (87 -
119)USB.</p>
<p>More details can be found in the link:<a
href="http://www.iram.es/IRAMES/mainWiki/EmirforAstronomers">
http://www.iram.es/IRAMES/mainWiki/EmirforAstronomers</a></p>
<p>The LO step size depends on the resolution of the reference
synthe used x the factor of the phase loop. Typically 100Hz to
1KHz.</p>
<p>Best regards,</p>
<p>Salvador<br>
</p>

Dear colleagues,
<div class=""><br class="">
</div>
<div class="">for planning VLBI spectral line observations with
the GMVA I would like to ask you for an update of the</div>
<div class="">3mm IF and tuning capabilities of your station.</div>
<div class=""><br class="">
</div>
<div class="">Please provide feedback of:</div>
<div class="">- frequency range covered in the 3mm band</div>
<div class="">- sideband restrictions (e.g. only USB)</div>
<div class="">- tuning capabilities (LO step sizes etc.)</div>
<div class=""><br class="">
</div>
<div class="">@VLBA: please ignore this request. The current
capabilities were already discussed with W.Brisken.</div>
<div class=""><br class="">
</div>
<div class="">Many thanks,</div>
