Question 1

Am i reading correctly that this should not be used with ham it up as it will overheat?...trying to reduce the noise in my shortwave reception

Accepted Answer

I have been using a Nooelec NESDR SMArTee XTR SDR - Premium RTL-SDR w/ Extended Tuning Range, Aluminum Enclosure, Bias Tee, with the Ham It Up Plus with no problems.  The Bias Tee, with it being enabled all time means that you cannot have an input which has a DC short circuit, such as a folded dipole, and this is a pain.  I have also used the same one as in the query without issue, but am using that with Bias Tee powered 2m linear amplifier.

Question 2

I bought the hamit up from you last week. the sdr part is getting red hot after 5mns. cannot use it because of heat.

It may be because you're using the SMArTee dongle and not the  Nooelec NESDR SMArt .
the smartee version supplies up to 200ma to power preamps..it cannot be switched off.
 If the HAMitup presents a loop i/p the smartee will try to give the full 200ma and get hot.
Nooelec supply the Nooelec NESDR SMArt in their bundle with the hamitup.
Check the i/p of the Hamitup with a meter , if it shows close to short cct thats the problem.

Question 3

Are there any drawbacks to this smartee model compared to the basic smart? i have a smartee but want a second. wondering if any benefit to just smart?

Accepted Answer

No, the circuit design of SMArTee v2 and SMArt v4 are effectively the same.  The difference is this has the bias tee (DC injector) circuit.  It was designed to not affect performance over the frequency capability of the device, and does not--even in sensitive lab tests.  If you don't mind the few extra quid you are generally better off with another SMArTee.  The only exception I can think of is if you want to use an antenna that represents as zero ohm to the SDR (very rare).  You cannot use that type of antenna with the SMArTee but can with the SMArt.

Thanks for your support!

Question 4

Will this work on an android tablet using an otg cable usb adapter

Accepted Answer

Yes, the NESDR is compatible with Android, provided you install the correct drivers as per our Installation Guide. However, the processing power in a tablet is lower than on a PC, so you may see some performance issues depending on your application and the required software.
