radio carries the UPD2824 , can be modded for more channels if the chip is changed or a expo type board is used (otherwise you can forget it ) , the radio is very simalar to many other radios , sames as the Uniden PC 244 . Uniden PC-122 , Cobra 146GTL , TRC-465 , AR-144 , PRO-640e , and a hand full of others , these radios in my parts were always known for there loud sounding audio qualities on AM and all worked very well on SSB , I think they are much better receiving radios on the SSB side of things. The other good side of many of these radios was that they added mic gains to them , many of the radios DID NOT have mic gains on them .......Why ? I'll never know. All in all , all are decent radios usually picked up on Ebay for about 40 to 50 shipped , compared to what you can get for that new , (and that aint much) these radios are a steal at those prices !!
