So, while TSH tells you how responsive your thyroid gland is to thyroid hormone it doesn't give information on your free thyroid hormone levels. This rise in TSH is almost always seen as an early and sensitive marker for thyroid dysfunction! This process is how your brain and your thyroid gland regulate thyroid hormones in your blood.Īs thyroid hormones drop your TSH will rise to compensate to tell your gland to produce more. If your TSH is elevated this means your brain is trying to increase the 'stimulus' to your thyroid gland in an attempt to compensate for decreased thyroid hormone (1). Its job is to act on your thyroid gland (in your neck) to tell your thyroid to produce more thyroid hormone. TSH (also known as thyroid stimulating hormone) is a hormone that is produced by the pituitary gland. In order to understand this concept, you have to understand how TSH functions in your body.

That might help to be prepared when installing the first RFX.The first thing you should know is that having a high TSH, even if accompanied by a normal T4, is never a normal sign.Ī high TSH is a marker that the connection between your brain and your thyroid may not be functioning at 100%. In USA these amplifiers are very popular and on the internet you can find many videos and reviews.

It is necessarily to have good technical knowledge to install RFX types. The RFX85HD is your choice for 10 meter radio repairs and upgrades when all your replacing is the final transistor or no transistors.īoth RFX85 units feature the new fan-ready heatsink design and variable bias controls for better tuning on SSB radio installations. The RFX85HD circuit includes only the final amplifier stage and low pass filter which makes for a much quicker and easier installation.

The RFX85 is your choice for 10 meter radio repairs and upgrades that require replacing the radio’s driver and final amplification stages. The RFX85 Circuit includes driver stage, final amplifer stage and low pass filter. There are now 2 RFX85 Choices: the Standard RFX85 and the New RFX85HD High Drive. However, it is recommended to attach it to the transceiver’s PCB because some transceivers come equipped with antenna warning systems, or other circuits, that are on ancillary boards between the recommended connection point and the antenna connector. * It is possible to attach the RF OUT coax directly to the antenna connector. G) The incoming receive signal is sampled from C14 and connected to the receive strip of the transceiver through the RFX75’s coaxial cable marked RX OUT.

This is sent to the S-meter detection circuit in the transceiver through the yellow wire.į) The final RF output signal of the RFX75 is sent back to the radio through the RF OUT coaxial cable where it is connected with the transceiver’s antenna connector *. The RFX75 mounts to the back of most transceivers with little or no modification to the transceiver’s chassis.ī) Once installed, the transmitted RF signal from the output of the transceiver’s driver stage (or pre-driver stage) is sent to the RFX75 via the coaxial cable marked RF IN.Ĭ) The driver signal is then amplified through the RFX75‘s ERF2030 (FET1) and then again through the ERF7530 (FET2).ĭ) The amplified signal from the ERF7530 passes through the RFX75’s efficient low pass filter.Į) A small portion of the signal is sampled through C19 and rectified through D3 and D4. THEORY OF OPERATION OF POWERBAND TYPES, DESCRIPTION OF RFX75:Ī) The RFX75 replaces the transceiver’s final amplifier stage and low pass filter section. Most installations will see 75 – 100 watts PEP output power. The output power of the RFX75 varies depending on the transceiver that it is installed on. The RFX75 features the latest Power MOSFET technology and a built in S-meter detection circuit.

The RFX75 is a RF final output stage and low pass filter designed as a replacement and/or upgrade for most 10-meter amateur transceivers. RFX75 is an Amplifier, 75 – 100 Watt PEP Output Power, RF Final Output Stage and Low Pass Filter, Designed as a replacement and/or upgrade for most 10 meter amateur transceivers.

Under the name POWERBAND, the company PALOMAR in USA sells a line ofĤ types of high power replacement final amplifier sections with high performance low pass filter for 10 meter amateur transceivers.Īfter RFX75 and RFX150 they now introduce the RFX85 and RFX85HD.
